1. Is white charcoal charcoal?

Carbon is a collective name for charcoal products. It usually includes four categories: white charcoal, black charcoal, activated carbon, and mechanism charcoal. White charcoal is also a type of charcoal. As early as Qin and Han, white charcoal had appeared in China.The fuel is used for smelting iron weapons, which can melt the fuel that can melt steel.

2. What is the difference between white charcoal and ordinary charcoal

White charcoal is also called white charcoal, which belongs to charcoal products, but compared with ordinary charcoal, white charcoal is different:

1. Different carbonized temperature

White charcoal is a high -temperature charcoal. The carbon with a carbonized temperature of 700 C is called high -temperature charcoal, while the carbonization temperature of white charcoal is as high as 2000 C.

2. Burning temperature is different

When the white charcoal is burning, the temperature can reach about 1000 C, which is much higher than the 500 C of ordinary charcoal.

3. Different combustion effects

After high -temperature refined white charcoal, it has the combustion effect of smoke -free and fire, and ordinary charcoal dripping oil will fire.

4. Different sources of raw materials

Ordinary charcoal can be made with any wooden raw materials, and the mechanism can even use agricultural and forestry waste; white charcoal needs to use hard wood.

5. Different market prices

The price of white charcoal is much more expensive than ordinary charcoal. Ordinary charcoal is generally one yuan to a few dollars a pound, while the price of white charcoal is about 2-10 yuan per catty, and the expensive is even more than ten yuan per catty.

What is white charcoal?

White charcoal is a technology of firing charcoal. In addition to the different firing method and ordinary charcoal, the differences in raw materials will also affect the quality of white charcoal. Not all wood can be fired white charcoal.

Generally speaking, the raw materials of white carbon must have at least 0.8 wood. Ordinary fruit wood and birch can also be fired.If you want to burn high -quality white charcoal, you still need to use the tree of Tochigi. Commonly used such as Wugang Masa, Qinggang , and other ingredients such as .

The difference between football and basketball

First: football feet (except goalkeeper), basketball hands;

Second: less football scores,0The0It is commonplace, how can basketball score two or three (girls often appear when girls play3The2Such a score);

Third: The requirements of football on time are not very strict. The stoppage time is inaccurate. It also depends on the mood of the referee. The basketball is precise.0.01Second;

Fourth: football11Personal kick, basketball5It's enough;

Fifth: I can find a venue for a football in my amateur enthusiasts, and it is normal to set the door with clothes. If there is no basketball, it is annoyed for a while;

Sixth: football is smaller than basketball;

Seventh: football has more contact and collision than the body of basketball, and the referees are wider;

Eighth: The football field is larger than the basketball court;

Ninth: football is the world's first movement, and basketball is not.

How big is the influence of basketball and football

Different countries, sports focus on different places is different. In terms of worldwide, the influence of football must definitely exceed basketball, and it has also opened a large gap.As far as Europe is concerned, basketball loves you much attention, and in the Champions League in most people, only Real Madrid, Olympiakos and other teams can remember fans.

And football can be described as in Europe. Not only each five major leagues are the focus of people's attention, but also the annual European Champions Cup League will attract the attention of the people around the world. The two projects cannot be compared at all.Some people will mention the United StatesNBA,althoughNBAIt is the highest basketball alliance in the world, but in fact, in the United States, it can only be regarded as the fourth largest sports. There are three major projects in football, Baseball, and ice hockey before basketball.That's why you lock your eyes here.

In China, there is no use in China. China's basketball development is much better than football. Yao Ming is an indispensable factor. He contributed to the promotion of basketball in China.There are many reasons such as education. In fact, there are many Chinese football fans, but the national team's performance is not good again and again, which also makes fans extremely sad.

Using the Super LeagueCBACompare,CBAIt can be said that it has become the highest level league in Asia, and the Chinese Super League has not yet had any influence abroad, but it has to be mentioned that basketball is5In the game, one or two foreign aids can greatly improve the viewing of the game, and football is11In the game, the enhancement of the players in the game is not as obvious as football.

In summary, in other countries in Asia, the degree of attention of football is generally higher than basketball. In the era of civilization, the sports level of a country can reflect the cultural advanced level of this country.A sport that is noticeable.

1. What does the seedling pot mean?

The seedling pot is also called a acupoint basin, which is used to bred seedlings.It is a Square disk, which is one Square, just like a small cup connected together,There are many bottom holes at the bottom,It can be used for sowing or cuttings.

The nutritional bowl is a very soft plastic basin. It is one -time. Basically, it is used when the sellers are raised in large quantities. The price is very cheap. Once the seedlings grow to a certain extent, it is useless.The two -color pot is also soft, but it is slightly harder than nutrients. It cannot move frequently, otherwise the potting soil is easy to disconnect, resulting in small seedlings that cannot grow normally.The material of the Jiali pot is slightly stronger, the bottom of the pot is more breathable, the use time is longer, and the price is quite affordable, so it is suitable for use when raising seedlings at home.

2. Can the seedling pot be used as a Flower pot?

The newly bought flowers and plants are generally planted in seedling pots. The large area of flowers in the greenhouse is used in this Flower pot.The seedling pot is thin and soft, the price is low, and the breathability is good. When cultivating, it is placed directly on the ground. After watering, the water permeability is good and the grounding is the best choice for seedling.

After we buy it, we will have a period of time. It is best to change a Flower pot. The seedling pot is not suitable for long -term use.Because the seedling pot and the potting soil are not strong, the water is leaked quickly after watering, and the water retention is particularly poor, and it is more time -consuming.At the same time, the wall of seedling pots is thin, not anti -sun in summer, not warm in winter, which is not good for the health of flowers and plants.

1. What is a beach bag

The beach bag is a bag that is suitable for back on the beach. It is slightly larger than ordinary Bags. The style is more casual and casual. It can put sunscreen, water cups, Skin care products, etc., which is a bit like the straw bag.

2. Can the beach bag be washed?

The beach bag is mainly used on the beach. Every time you go to the beach, there will be some dirt on the bag. Sometimes it will even be stained with oil, which will affect the beauty. However, due to the special style of the beach bag, many friends are worried about the beach bag.Can't wash, can the beach bag be washed?

Generally, the beach bag can be washed, but you must pay attention to the method of washing. You can see it when you buy it or wash the water label.Washing in the washing machine and not brushing with a brush, otherwise it will be easily deformed, usually it is recommended to wash it.

Third, how to wash the beach bag

The cleaning method of the beach bag is generally hand -washing. The specific cleaning method is:

1. Put a pot of water, add an appropriate amount of laundry powder to it, put the beach bag in it, and soak for about a day.

2. After soaking, take out the beach, and gently wipe it with a soft cloth.

3. If there is oil or other obvious stains on the beach bag, you can drop a few drops of detergent before soaking in water. After 2 minutes, rinse with water and then soak it.It's right.

4. After cleaning, put the beach in a ventilated and cool place.

What is mobile phone positioning

mobile phone positioning refers to the location information (latitude and longitude coordinates) of mobile phones or end users through specific positioning technology, and marked the technology or service of the position of the positioning object on the electronic map.There are two types of positioning technology, one is based onGPS The positioning of the positioning is based on the base station of the mobile operation network.based on GPS The positioning method is to use the mobile phone GPS The positioning module sends its own location signal to the positioning background to achieve mobile phone positioning.The base station positioning uses the calculation distance of the base station's distance to determine the location of the mobile phone.The latter does not need a mobile phone to have GPS Positioning ability, but the accuracy depends to a large extent on the distribution and coverage of the base station, and the error will exceed one kilometer.The former has a higher positioning accuracy.Also use wifi Positioning in a small range.

The principle of mobile phone positioning

mobile phone positioning refers to through the wireless terminal(( cell phone Cure Coordinate with the wireless network to determine the actual location information of the mobile user (( Lepatinity coordinate data, including 3D data Cure ,pass SMS As well as MMS Voice is sent to users or provides some value -added services based on this.Positioning service is also called mobile location service (Location Based Service ,, LBS) , It is the network of telecommunications mobile operators (( like GSM net, CDMA net Cure Get the location information of mobile terminal users (( Latitude coordinates Cure With the support of the electronic map platform, it provides users with a value -added business for corresponding services.

mobile phone positioning is usedGSM The honeycomb technology of the mobile communication network to realize the location information query, GSM The wireless communication network is built from many communities like bee honeycomb. Each community has its own number. You can know the area where the mobile phone is located through the identification number of the mobile phone.At present, the positioning technology of mobile phone communities is still perfect, and the accuracy range in the urban area is roughly 200 About rice, the accuracy range of the suburbs is roughly 1000 rice ~ 2000 With around the rice, with the continuous development of the technology of mobile companies, I believe the accuracy will be further improved to further 50 Within rice.At the same time, the landmark name displayed at the same time is still optimized. As further optimization, the landmark will be more accurate.

Honeycomb positioning technology also belongs to the LBS base position positioning. This positioning method is commonly known as the ground positioning system because it relies on the signal tower distributed by the operator to obtain the latitude and longitude information to determine the position of the terminal.As long as all mobile phone cards are in the activation state, and can normally receive calls, they can be accurately located. Strong positioning capabilities, positioning signals can effectively penetrate the building, basement, and tunnel traffic.Each mobile phone card has the only identification code, just like a phone call, each number is the only point to the fixed mobile phone, the LBS base station positioning can also effectively find a fixed number through this recognition code to find a fixed number numberThe location of the mobile phone is presented to the electronic map. Such positioning technologies are compulsory and are widely used in some regulatory fields.

Features of mobile phone positioning

1 High coverage

On the one hand, the range of coverage is large enough.On the other hand, the scope of coverage includes indoor.Most of the time users use this function in the room, from high -rise buildings and underground facilities must be covered to each corner.According to the scope of the coverage rate, mobile phone positioning can be divided into three types of coverage services: the entire local network, covering some local networks, and providing roaming network services types.In addition to considering the coverage rate, the environmental factors of the network structure and dynamic changes may also make a telecommunications operator unable to guarantee services in local or roaming networks.

2 , Positioning accuracy

mobile phone positioning should provide different accuracy services according to the different user service needs, and can provide users with the right to select accuracy.For example, the United StatesFCC The positioning accuracy launched is 50 The probability within the rice is 67% , Positioning accuracy 150 The probability within the rice is 90% EssenceOn the one hand, the positioning accuracy is related to the positioning technology adopted, and it depends on the external environment of the business, including the radio communication environment, the density and geographical location of the base station, and the equipment used in positioning.

The role of mobile phone positioning

1. Parents position the elderly and children

It is mainly due to the needs of security and care. It is installed on the mobile phone of the elderly and children. Once lost, send a text message to get the specific map location of the elderly and children.

2 , Enterprise Management of Vehicle

GPS The signal is transmitted through satellite, restricted by the cloud layer and obscuration, there will be no signal in cloudy, basement, and tunnels to generate blind spots.Based on sim The positioning technology of the card is what we call the ground positioning -the enterprise effective LBS The positioning of the base station can effectively feedback the location information on the location on the ground. LBS The base station positioning saves the terminal cost, and the existing mobile terminal can be used directly, which saves the entire project cost. LBS Suitable for regulatory positioning requirements, and continuous positioning communication tariffs are relatively high.

3 The management of employees by enterprises

It can provide management for sales companies with multiple branches and work hours of sales staff. ; Mainly use base station positioning, which can be positioned with foreign duty employees to achieve mobile attendance, itinerary management, trajectory inquiry, visit management, etc., improve employee work efficiency, and reduce travel costs.

4 , Make remote decoding

The internal program where the opponent's number is located or fixed -line is bound to his number. After the binding, you can perform unlimited distance monitoring, interception, and positioning function.

What are the ways of mobile phone positioning

1. GPS position

Actually, I do nt need to say, everyone must know, first of allGPS Positioning, in general, the current mobile phone chip is supported GPS The positioning, that is, you don't want to support it, you can't be positioned.

2. WIFI position

Thenwifi Positioning, each wifi There is a unique one mac Address, when the mobile phone is turned on wifi At that time, it starts scanning and collecting surrounding routers wifi Signals, upload their location information to the server to form a huge hot spot position database.

This iswifi position.Although you can close it in theory, some you can't close it, because some software is like checking the household registration, you must support positioning to use.

3 , Base station positioning

There is also a positioning method, that is, the base station positioning, that is, the base station can locate your mobile phone through your mobile phone card.As long as your phone has a signal, others can track your position by checking which base station has contacted your phone.

In simple terms, at present, the approximate way of positioning is these.
