How to train

1 As well as Accelerating the training method of free landing, which is often saidAFF

This training is a licensed coach grab the students when parachuting and show certain skills.Because students wear their own parachutes, he must receive ground training of emergency procedures and landing procedures.AFF Training usually includes several hours of ground training, and the first jump can usually be completed on the same day.

Student and twoUSPa Aff The coach leaves the plane together and falls freely together 30 to 50 Second, the specific depends on the jump height, usually 10000 to 13000 foot.The coach maintains the control of the student's seat Belt to provide air guidance and assist in stability when necessary.Student 4000 Open your parachute and land on the landing area. AFF Training requires more teaching staff to participate, so it is a relatively expensive method in various methods.

2 As well as Stable line training method

The stable wire is a cable or webbing. One end is fixed on the parachute and the other end is fixed on some parts of the aircraft. It is used to expand or partial parachute when the student leaves the plane.Teachers will not jump with students in these two methods.

Static training and the first jump can usually be completed on the same day.Students jumped out of the plane while the parachute started.Usually3500 Jump out, and then the students operate the parachute to the landing area.spend Usually compareAFF Low 100 DollarEssence

3 As well as Double Umbrella Training Method

Most parachute bases use double umbrella teaching methods to guide students to gradually switch to single -person skydiving.The coach operates a parachute and shares a parachute with students.The training time is shorter than the student's independent operation.traintime Usually less than30 minute.

Students and coaches are connected to the same parachute and pass by together30-50 The free fall of the second depends on the level of skydiving, usually in 10000-13000 foot.They use a single but larger parachute and have a dual control handle.Spend more than AFF The training method is cheap 100 US dollars.

What to pay attention

1, Listen carefully

Now the popular double skydiving, which brings convenience to users who experience parachuting. You only need to listen carefully before the training, and remember that the movement and knowledge points of the coach said.You just need to appreciate the beauty, it's okay to have a concave shapeEssence

2, Stable mood

Many people experienced the first time and are more or less nervous. It may be that their own psychological construction is too strong. It is recommended that you try not to set too much psychological limitations. Try to use the method that suits you.Essence

3, Believe in coach with you

The coaches of these skydiving bases are thousands of skydiving experience for thousands or even tens of thousands of times, so I believe your coach, if you have any uneasiness or anxiety, and fear, you can tell youEssence

4, Like one"banana" Same

When parachuting, your body should imitate the shape of the banana. When you are in half, this means that your head is tilted backwards. Looking at the horizon in front of you, the back of the arch, the arms extend to the sides comfortably, the soles of the shoe sole, the soles of the shoeShould be directed to the skyEssence

5. Parachute preparation

1 . Try to wear casual comfort as much as possible, do not wear too many buttons;

2 . Girls should not wear shoes with heels, mainly sports shoes and casual shoes;

3 . The parachuting is greatly affected by the weather. It is recommended to advance in advance2-7 To make an appointment, communicate well with customer service;

4 . For safety reasons, the electronic products and necklaces, rings and other jewelry cannot be worn in their hands.

Basic action of skydiving

The basic action of parachuting is to accept qi, take breathing correctly, relies on both ears to analyze the airflow, and then adjust the various parts of the body, make the body in a balanced state, know how to keep the umbrella, open the umbrella, the main umbrella in time, and quickly analyze the analysis.50 In the rice range, the airflow snail, control your main umbrella according to the airflow, and finally the key: understand the correct timing of the main umbrella cutting and a side umbrella.therefore Novices are afraid of out of the cabin,, Old hands are afraid of landing,, This is the best description of the skydiving exercise.

one,BabiesHow to choose a size

1. In terms of size, the most important thing is to use the length of the baby and the bust as the specification of the size, and should not be selected according to the age of the baby.Because the baby grows rapidly, the height changes, and the pure cotton texture generally has a shrinkage rate of 3 to 5%. Therefore, pay attention to buying as much as possible when you buy.5 cm tall and not more than 10 cm.

2. General jumpsuit pants can be opened for convenience to change diapers.Therefore, you should pay attention to the style when choosing your baby's pants, and try to choose to wear and take off.It is best to wear linked underwear at night, so that the navel can not be cold.

3. There are more and more fiber clothes on the market. Chemical fiber belongs to chemical products and is likely to cause Skin allergic reactions. Therefore, when buying clothes for children, we must insist on buying breathable, dissipated, and moisturizing pure cotton fabrics.And cotton clothes have good hygroscopicity, which is in line with the characteristics of the baby's prone to sweating.

2. How to wear a baby's body clothes

Generally speaking, if the baby is still young and you need to use diapers, then wearing jumpsuits is also a better choice.It is better to wear your baby's underwear underwear, which is not only healthier and more comfortable for the baby.When the baby is too young, there is no waist and a large belly. If you wear a split with pants, it is easy to hold the baby's belly if it is too tight.

1. First open the one -piece clothes button, lay it on the bed, and then put the baby on the jacket.

2. Then first wear the sleeves on one side, and then wear the other side. Pay attention not to hurt the baby's arm.

3. Finally, wear your legs, and then buckle the buttons.

Third, how to change the jacketdiapers

1. For the baby of the young moon, you can put the baby in a higher place, unbutton the liquor of the clothes, push the clothes to the baby's back, and then replace it.

2. If the coat is with pants, you need to pull the baby's leg out of the pants first, and then replace it.

3. The baby who is a little bigger can stand directly and unlock the buttons of his clothes for replacement.

4. For the connective jacket of the gear, you only need to open all the buttons to easily change the diapers for the baby.

5. If the weather is hot, you can take off your baby's jacket directly and replace diapers.

[GPS Technology] The main key technology of GPS chip is the three generations of GPS chips 9 major knowledge

With the development of science and technology, the development of GPS navigation is increasingly worth looking forward to, and the development of the core technology of GPS chip is the most worthy of our concern.In the process of the development of GPS chips, "miniaturization" has always been an important development direction, which has led the GPS chipset to reduce power consumption and reduce volume.The system can provide detailed and accurate positioning information and traffic information, which can easily achieve the CPS satellite navigation function.

In recent years, due to the increase in chip manufacturers and providing integrity solutions, module manufacturers are more likely to develop integrated products. Therefore, a large number of manufacturers have invested in the production of receiver products.The effect of helping the GPS boom has also caused the price of GPS chips with the highest cost of GPS machine costs, and the GPS chip used to provide consumer electronics products has also begun to show their figures. In addition, chip manufacturers have gradually improved their performance performanceTherefore, the chip positioning ability has gradually closer.Under this trend, how GPS chip products win the affirmation of buyers, and have become the key factor in competing with each GPS chip in the market.

Speaking of the main key technologies of GPS chips, this includes responsible signal processing -base frequency (Baseband) and receiving signal -RF (RF).Since the GPS signal frequency (1575.42MHz) comes from a high altitude of 20,000 kilometers from the ground, the signal is very unstable, so the antenna receiving signal has been enlarged, filtered noise, frequency reduction, and sampling (RFFRORONT END) after the antenna receiving signal, and then passes throughAfter RF, the signal enters the base frequency processing section, and the digital signal sampled in the previous paragraph is calculated and output to facilitate the use of user interfaces. Among them, the GPS Baseband DSP chip is the core component, which is responsible for processing the address signal.

Based on the above, the two parts of RF and the base frequency include micro -processor Microprocessar, low noise amplifier (LNA), digital ections, RF Section, antenna Ele -Ment.), Output into several important components of the drive (GPI andDrivers) and the PRO -CESSOR PERIPHERALS.The integration of various GPS chip solutions on the market makes the GPS chip market is facing great variables.The first is "miniaturization". Looking back at the development history of GPS chips in recent years, with the combination of GPS and other products, and emphasizing that the volume of the terminal product is light and short, the GPS chip direction of the system single chipization of the system is an inevitable trend.At present, manufacturers can divide radio frequency or base frequency single chips for GPS single -chipization, and integrate more functionality.In the RF chip part, many manufacturers have integrated amplifier, filter, frequency reduction, frequency synthesizer and oscillator;Flash), power management time clock, etc.

Therefore, we see that the size of the GPS chip has gradually narrowed, and the GPS chip has developed from a dual module to a single module. In the future, GPS equipment products will become more and more vigorous, and chip demand will become greater.In addition, GPS chips will also face customer -based demand. In the past, most GPS chips were in the automotive market.At present, GPS chip applications have begun to be used in mobile phones and PDAs, or special personal carrying devices, such as the tracker for the elderly and children.The GPS chip may also be integrated with other functions, such as Bluetooth, USB, etc.Therefore, more and more customized modules designed for special applications will also be increasing.At present, most of the global investment in GPS chip development is mostly with foreign manufacturers, such as Sirf, Ti, XEMICS, FreeScalc, STM and other large manufacturers have launched GPS chips. Among them, Sirf is the world's largest GPS chip manufacturer. The product line is quite complete and can provide a full range of series.Solution product.

GPSKnowledge descriptionGPS"Three -generation chip" knowledge

Recently, in GPS products, the so -called "three -generation chips" are often mentioned.However, neither merchants and users have clearly explained and understand, and even misleading and misunderstanding.Exchange your own experience and views with you.

1. GPS chip: There are currently three main chips on the international (common/more popular) GPS module (common/more popular) GPS module (common/more popular) GPS module (OEM board).

(1) American SIRF (SIRF)

(2) Sony (Sony Ericsson/Sony Ericsson) chip

(3) Swiss Nenem NEMERIX chip

2. The core of the third -generation chip:

The chip hardware is similar, but internal software plays a main role.The so -called core technology of the three generations is only to improve the software algorithm on the basis of the 2nd generation. It is like the formula for calculating the acceleration/speed in the primary and high school physics classes, but in the university's higher mathematics, the number of guides and points in the university to calculate the same acceleration/The physical problems (algorithms) of speed are different. The time used is very different. It reflects the difference between middle school and university, just like the 2nd and 3rd generations.The second is that the hardware also provides quality standards.

3. The main function of the three -generation chip software:

3 generations of chip software improvement upgrade: (1) Algorithm improvement improves the stars/positioning speed time.(2) Improve anti -interference performance, signal -to -noise ratio, and receive effective star numbers through software filters.(3) Some chip implementation software DR trace (rotation) calculation, improving anti -high -rise buildings, shade, underpass cover and tunnel function.(4) soft channel search, search to increase the number of channels for visual satellites (12-24), and can continue to position when personnel, vehicles, uphill, and posture changes, airplanes, and Ship star calendars changes.

4. Three -generation chip hardware improvement:

(1) The power consumption of the chip is reduced and the volume is reduced (compared with the 2nd generation).

(2) Improve anti -interference capacity, full shielding or dual chip separation.

5. GPS module and product:

gpsgpsEven wires, connectors, etc. look irrelevant components).

6, antenna is an important factor:

GPS antennas must be used in common GPS products such as handheld, PDA, Bluetooth, G-MOUSE, etc., regardless of active, passive, or even omniscient antenna, more than a dozen performance indicators, angle (except for 1600 maximum full antenna), DB of amplifiers, impedance range, material, anti-interference ability and module matching determine the performance of the entire product, and even 2-3 antennas (above and bottom) on the aircraft.position.In other words, the 3 -generation module is very good, and the antenna may not match the 2nd generation products.

7, number of channels:

Three stars are two-dimensional, 4 stars are three-dimensional positioning. This is the basic principle of GPS. We use 11-12 pieces on the ground (because the antenna is 160 degrees angle).) You can collect a few more (must be omnidirectional or more or more antennas), but it also takes 3-4 of the 3-4 signal and the nearest effective satellite for calculation positioning.Four channel positioning, a channel quickly search for all visual satellites, and compared with 4 of the effective stars, it is replaced by one of them, so that 4 strongest signal satellites are maintained.Therefore, the higher the passage, the better, the generally 12 are enough. What 16, 18, 20, 24 ... are soft channels, which reflect the number of visible satellites that can be searched for viewing satellites. It has no practical significance.

8. Induction (DB number):

The degree of induction of GPS receiving signal (-150-195DB) The standards of each manufacturer are not uniform, some are modules, some are modules contain antenna, some are the average, some are peaks (maximum value).Everyone's actual environment (electric field, magnetic field, high-voltage, microwave, geomagnetic ...) is very different. Therefore, the difference between this indicator is 3-5DB, which is not related to the order of order, but it is probably a approximate reference.

9. The obvious advantages of third -generation products (actual effects):

As long as the user needs to understand the specific technical indicators of the three -generation chip, it is more important to observe whether there is the following characteristics.

(1) Fast positioning time: Regardless of the cold start, Wen Qi, and the heat, the re-capture time is almost 5-30 seconds (compared to the second generation). In fact, most users are not worse than these ten seconds.

(2) High sensitivity: that is, in high -rise buildings, shade, underpass, cover files, Suidong, windows, cars, and even under the chassis of the car, you can quickly position more than 4 satellites.It is often said that it can be positioned a bit (single -star positioning), that is, "Give some Sunshine".

(3) Anti -interference performance: high -voltage lines, electric fields, magnetic fields, high -speed dynamics, microwaves, mobile phones, can still work properly in the environment of frequency interference.

(4) Low power consumption and power saving: reduce power consumption, and even have sleep state (static does not work), which can save power and improve product standby time.

(5) Small volume, good performance and price comparison: small volume and light weight. This is the needs and development trend of society, which can expand more application scope and field.In fact, the price of the three-generation chip should be the same as the second generation, or even lower, but the function is much improved. T-38 (16 channels, 3rd generations) 200-300 yuan/block.

Hide fun

The blue sky, the white snow, when the sun is spreading, this is a gift from the world to us!Snowboard -an ordinary Tool, but the key to opening this gift, so that we can enjoy the fun of skiing! Make your body immersed in the tempting blue sky and white snow, galloping horizontally on the snow, and rushing along the snow channel, feeling the wind through the side, as if tore the air.Release ourselves as much as you can, feel the speed that the speed brings us, the passion is released from the heart to the body, and the energy bursts from the body to nature.Such temptation, even if a person who doesn't like to move no matter how quiet no reason does not like it.Speed and passion, this is the charm of skiing!

Best of skiing

1. Flexible body & strengthen balance ability

skiing is a systemic exercise that allows the nervous system to be fully exercised and improved.While bringing us speed enjoyment, we also have a good exercise ability, coordination ability and flexibility.The essence of skiing is to master the process of balance and find the balance point in the switching of the center of gravity, so as to make beautiful movements.This enhancement of this balance cannot be obtained from Running and playing.The closeness to the balance is coordination ability.Only by fully coordinating each part of the whole body can the best balance effect in the taxi.Ski is almost all the joints of the human body, neck, hand, wrist, elbow, arms, shoulders, waist, legs, knees, ankles, etc., which can play a better exercise role and activate a stiff body.Make the body's flexibility.

2. Burning fat

skiing, like Running and swimming, is also an aerobic exercise, which can enhance cardiopulmonary function.Ski requires strong lung capacity and good cardiovascular system support, especially in high -speed exercise, cardiopulmonary function will be better improved.At the same time, the cold air in the ski resort will test the body's oxygen transportation system, which exercises the ability of cardiovascular shrinkage in virtual.According to the test, a normal Ski person consumed 734 calories an hour, which is equivalent to Running 9.5 kilometers of exercise in 1 hour.Therefore, the effect of skiing on fat burning and consumption is quite significant.

3. Treatment of "winter fatigue chain reaction"

The temperature in winter is low, and there are fewer Outdoor (Weibo) campaign, which makes a considerable number of people choose to be indoors.There are fewer outdoor sports in winter. Lack of exercise causes people's physical constitution to reduce their physical constitution, which is easy to cause fatigue, which makes it easy for emotions to be low, concentrated, and low work and learning efficiency.These symptoms can be summarized as "winter fatigue chain reactions".The symptoms of the lack of training on weekdays are particularly prominent.We all know that exercise is the best way to change emotions, especially outdoor sports are particularly prominent in changing negative emotions and improving status effects.Therefore, skiing, as a unique outdoor sports in winter, can perfectly treat the "winter fatigue chain reaction", especially on the snow tract quickly and fast skins, the treatment effect is better!

1. There are several lengths for Taiwan Fishing rods

As a pendant fishing method, the Taiwan fishing method is used by the majority of fishermen with its high sensitivity. The Taiwanese fishing method is generally selected. When the fishing rod is selected, the length of the fishing rod is comparison.One factor that cares about, so how many are the length of the fishing rod?

There are many standard lengths such as 3.6 meters, 4.5 meters, 5.4 meters, 6.3 meters, 7.2 meters, 8.1 meters, etc., as well as in order to meet a variety of needs, it produces 2.7 meters, 4.2 meters, and 5.7 meters.There are very few Fishing rods of 9 meters, 10 meters, 11 meters, and 12 meters.

2. How long is the most suitable fishing rod

Different lengths of Taiwan Fishing rods have their own advantages and disadvantages, just like people's fingers. Although the length is different, they are useful. It is not necessarily the most suitable for Taiwan fishing rod. When choosing, the following three major factors are considered:

1. Select the length of the fishing rod according to the water situation

(1) Water Shen

Whether it is a natural waters or artificially excavated waters, its depth is definitely different, and there are often different depths in a waters.Therefore, if more than 3 meters of water depth, we can be identified as deep water zone, then the fishing rod we use will be longer, at least 5.4 meters long, but deep water hidden fish is still recommendedThe pole, so that the big fish does not suffer, such as using a Taiwanese fishing rod with more than 6.3 meters, the best 7.2 meters.

If it is water depth below 3 meters, you can use a shorter fishing rod. For example, a 4.5 -meter fishing rod will be used frequently, but fishing in too shallow water, such as fishing within 1 meter, then fishing within 1 meter, thenIt is necessary to use a 2.7 -meter fishing rod, but if it is fishing in the waterweed area, it is another matter.

(2) Underwater condition

Before fishing in a strange environment, you should first understand the bottom of the water and determine after finding the bottom. If there are many obstacles such as waterweed or other stones at the bottom of the water, then you must avoid these things.Determine the length of the fishing rod.For example: If the aquatic grass is distributed on the shore, then choose a longer fishing rod. If the aquatic grass is distributed in the distance, you must choose a shorter Taiwan fishing rod.

Another situation is the choice of the shape and direction of the bottom of the water. For example, the carp is often hidden in the place where there is a slope.At the bottom of the flat terrain, the line group will be tilted. In this way, the wind line is too short. Whether it is the performance of the floating sensitivity or the slippery fish after the fish, it will have a great impact, so you must choose to chooseThe longer Taiwanese fishing rod is cope with the slope terrain.

(3) Water visibility

fishing in the clear waters can only have the opportunity to touch the waters where the fish group moves; if the water quality in the water is turbid, even if the water is very light, the fish does not have much sense of crisis, because it does not see the land, it cannot see the land, it cant see the land, it cant see the land, it cant see the land, it cant see the land, it cant see the land, it cant see the land, it cant see the land, it cant see the land, it cant see the land, it cant see the land, it cant see the land, it cant see the land, it does not see the land, it cant see the land, it cant see the land, it cant see the land, it cant see the land, it cannot see the land, it cannot see the land.The hunter couldn't find it.So when we do fishing, we can use a shorter fishing rod, and we can get a good harvest.

(4) Water nature

In terms of the size of the water area, there are rivers and lakes in a large area of waters. When we fish in these places, the Fishing rods must be longer, which is at least 7.2 meters.A few acres of ponds are used for fishing, and the 4.5 -meter fishing rod is the most commonly used.

In addition, from the professionalism of the waters, the crowds targeted by Hekeng are more professional, so there is some restrictions on the length of the fishing rod, and the use of a long pole is not allowed.However, in the case of wild fishing, the level of fishing is different, and there are no rules. So many people tend to choose long poles to fish, at least one inch, one inch, and strong. The probability of Running fish after fishing is greatly reduced.

2. Select the length of the fishing rod according to fish love

(1) fishing small and medium -sized fish

Small and medium -sized fish, mainly catfish, carp, catfish, etc., they have a low degree of perception of danger and like to find food on the shore, so we can often catch.Even if the big catfish is more cunning, because the growth is relatively small, the individual is relatively small, and the strength is relatively low. Therefore, the length of the fishing rod used in use does not need to be too long. For small and medium -sized fish, it is mainly based on 4.5 meters.Good ones can be shortened to 3.9 meters. Of course, it is best to cooperate with the fishing table.

(2) fishing large fish

The reason why big fish can grow up is their own survival skills and their perception of danger. They generally do not stay in the place near the shore, and they will only move in deep water or water central.Then we need to use a longer desk fishing rod, usually in the length of more than 6.3 meters, so as to approach their living waters. In addition, there is plenty of buffer space after the fish.fish.

3. Select the length of the fishing rod according to the fishing time

(1) Different seasons

spring fishing beach, summer fishing pond, autumn fishing yin, winter fishing.In spring, the fish and hunger after the winter are hungry. At this time, we will swim to the shallow water to find food.You need to use a long pole.In the summer, the Solar radiation is large and the water body is heating fast. Most fish will hide in the deep water area to avoid the heat in the deep water area, so we must use long poles to fish.autumn is a transition season. In the early autumn season, it continues the high temperature in summer. Therefore, it is necessary to fish deep water with long rods. The temperature is reduced in the late autumn. You can use a shorter fishing rod appropriately.As for winter, it is necessary to catch the Xiangyang District when it is sunny, and the shallow water is also the first to rise. The fish has a temperature. At this time, it is recommended to use a length of 4.5 meters.

(2) different time points

During the day, due to the sun, the water body will be illuminated, and the fish will be discovered by the predator when the fish moves in a lighter place. Coupled with the nature of the fish to avoid harm, it will stay away from the shore and hideIn the deep water area or where there are obstacles, then we should use a longer fishing rod during the day, at least this method when fishing.

When the sun falls and the night comes, it is dark, and basically no one can see anyone, then the fish is bolder. Coupled with the characteristics of eating, they are more willing to swim to find food from the shore.Therefore, when you do fishing at night, you can fish appropriately and use a short pole. Of course, if you catch big fish, you still need to prepare a long pole. In addition, you need to pay attention to the light cannot be directly illuminated by the light.

In general, how long the length of the Taiwan fishing rod is not a fixed thing. Due to the influence of many factors, the personal use habits of some fishermen also have a certain impact;It can be made up by seducting fish.
