1. Is it illegal construction?

This depends on where the telescopic Shading shed is built. Construction of telescopic Shading sheds in the community. Then this must be regarded as illegal buildings. Like the community, it must not be able to build a telescopic Shading shed or anti -theft net. After construction, it is built.All need to be demolished according to law. Now the management in the community is very strict.

However, if it is a house built in your own home, you can build a telescopic shade shed. This management will be slightly loose. Of course, it is best to consult with government staff before construction.It can be built so that it is not an illegal building.Of course, the construction of a telescopic shed must not take up additional homesteads.

2. How to install the telescopic Shading shed

1. When installing the telescopic shade shed, we must first measure the width of the door body to determine the installation position of the sunshade and mark it.

2. Next, we drilled on the wall and stuffed the expansion bolts into the hole.

3. In the next step, starting the shade shed fixed parts, such as telescopic arm, etc., we can use bolts to install fixed parts firmly.

4. Finally, we will fix the Shading cloth.

Third, why do I need to install a shade awning

1. It can effectively block the sun, thereby reducing the indoor temperature, reducing the frequency of emptiness, and reaching economic benefits.

2. You can also open the window when using a Tent to keep the indoor circulation in the air. At the same time, you must avoid direct sunlight to destroy indoor furniture.

3. It can develop the Outdoor space so that we can leisure and exercise on the balcony or platform, so that we will not be damaged by ultraviolet rays and harmful substances in the sun.

4. Add some personalized embellishments to the building, decorating home, can also make it more fashionable and artistic.

What Flower pots are better for flowers?

1. Wooden Flower pot

Wooden Flower pot is a flower container made of various wood processing.It is lightweight, has good breathability, has strong moisturizing and Fertilizer, low cost, and is suitable for planting of various flowers. In addition, it can also be determined and processed according to the shape, size and cultivation of flowers according to the shape, size and cultivation of flowers.

2. iron artifact

There are many iron artifacts for succulents, bird cages, flower rings, photo frames, heart -shaped flower artifacts, and so on.General iron moss is planted.There are also iron pots, which are suitable for use in the north, but in the summer, the iron basin should pay attention to Shading. You can put a layer of Shading net around the pot to avoid the temperature of the pot soil.

3. Cement flowerpot

Cement Flower pot is cast with cement mortar.It is simple, with different shapes, and moderate weight, but it is suitable for garden and balcony greening.

4. Ceramic pot

The ceramic Flower pot is made of various soil, which has been processed and shaped.Due to different processing methods, it can be divided into tiles, glaze, porcelain pots, purple sand pots, and plastic Flower pots.

5. glass flower ware

The glass flower is not breathable and cannot be watered.In summer, the glass flower must be placed in a cool place.Put the water layer with a glass flower, you can use pottery or large light stones.

Flower pot selection skills

When choosing a Flower pot, pay attention to the size, and the height should be appropriate.The Flower pot is too large, just like thin people wearing large clothes, which affects the beauty, and the Flower pot is large and the plant is small. The water absorption ability is relatively weak.After watering, the pot soil is kept moist for a long time.The Flower pot is too small, it looks heavy and light, and affects the root development.In addition, the size and height of the Flower pot are available for reference:

1. The diameter of the Flower pot should be generally lined with the crown diameter of the plant.

2,Plants with a mud ball, after putting in the Flower pot, there should be a 2-4 cm gap around the Flower pot to add the new soil.

3. Plants without mud balls, after the root system is put into the Flower pot, it must be stretched and should not be bent.If the main roots or the roots are too long, it can be properly trimmed, and then plant it into the pot.

How to put the flowers on the pot

1As well asBefore putting on the basin, put a nylon net at the drainage hole in the basin to prevent insects from entering from here and hurting flowers.

2As well asCover the tiles on the drainage holes, and the cultivation soil with coarse particles is used as a bottom soil, and the flower seedlings are placed in the center to make the flower seedlings stand upright.At this time, pay attention to spread the root system of the flower seedlings evenly on the soil, don't be together.After filling in the cultivation soil around the surroundings, the filling should finally be from the pot.2~3For centimeter, the large basin should be from the pot mouth4~6Centimeter, it is convenient to water.

3As well asAfter filling the soil, you should slightly pressure the soil.Flower seedlings are best to bring some soil groups, which will help the flower seedlings to go through the period of slowing the seedlings smoothly.

Note: Do not put the flower seedlings in the sun in direct sunlight after planting.The first watering must be poured through, knowing that the drainage holes on the bottom of the pot are flowing out.Wait until the surface of the pot soil2~3The centimeter has been dry, and then watering is then watered.

Flower potting skills

1As well asPrepare the cultivation soil and the corresponding Flower pots, as well as some tools or pots of pots or pots of pots.If the Flower pot used is a new pot of pottery, soak the water in advance; if the Flower pot is used is an old basin, it is necessary to take disinfection measures.

2As well asFlower pots should be properly watered or stopped water2~3God, when the pot soil is slightly dry, you can hold the plant in one hand, knock on the bottom of the pot and the wall of the pot, and separate the pot soil from the wall of the pot.If the flowers are pulled out when the pot soil is wet, the pot soil is easy to fall off, causing the root of the plant to be exposed, and the resistance increases when the flowers are pulled out, which is easy to hurt the roots.

3As well asRemove the soil balls on the plant about half of it, cut off the rotten roots, old roots, and dead roots, and loose the surrounding soil with a bamboo stick.Put gauze at the bottom of the Flower pot, put the new soil, place the plant in the center, fill the soil into the Flower pot, and compact after filling.

4As well asPut it in a well -ventilated and cool place for about a week.If flowers like high temperature and humidity, you can use a plastic cover to help them quickly return to growth.

Flower pine pot skills

1As well asFirst use bamboo sticks to loosen the soil along the basin of the basin. During the process of picking, the direction must be continuously changed to avoid hurting the root of the flower.

2. Hold the Flower pot in one hand, and continue to beat the flower basin wall in the other hand, and evenly pat the circle to make the soil in the flowerpot loose, and then loose the surface soil with nail rake.

3. Insert the potting soil with disposable chopsticks, and push it to the drainage holes on the bottom of the pot. After loose the pot soil, water it multiple times. Do not water each time. After the soil is moistPotted soil.

1. Who invented the surfing board

The first design revolution in the surfing board appeared in 1926. A man named Tombraker invented the hollow board, applied for a patent, and became a surfing celebrity at that time.In fact, this is the improved Euro board. He made a lot of holes on the mahogany to reduce light weight, and then sticked a thin wood piece on both sides and waterproof.Holding it may be like holding a sister paper.At the beginning, many Hawaiians laughed at him and called this plate called 'cigar plate', but when they saw the performance of this board, they didn't say anything.In 1930, the board began to mass production. In 1935, he invented the board fin, which greatly improved the stability of the board.

2. What is the development history of surfing boards?

The surfing board was about 5 meters long and weighing 50 to 60 kg.After the Second World War, a foam plastic board appeared, and the shape of the board was also improved.The surfing board is 1.5 to 2.7 meters long, about 60 cm wide, 7 to 10 cm thick, flat and flat, the front and rear ends are slightly narrow, and there is a stable tail fin at the rear.In order to increase friction, there is a waxy outer membrane on the board.The weight of all surfing boards is only 11 to 26 kg.

There are some ripple structures on the front side of the whale wings, which helps this behemoth to move forward in the water more elegantly and smoothly.This structure can help reduce resistance and help the humpback whales "seize" the water flow, so as to ensure that it can still act quickly although it has a huge body.Inspired by this, surfing board producers produced a ripple -like front end of the surfboard.

1. Where is the difference between Casual pants and sports pants

People often go out to exercise, maintain their health, and often buy the clothing required during exercise, such as sports pants, sports pants are more loose, comfortable to wear, and it is convenient for us to perform daily Running and gymnastics.You will also wear Casual pants, so what is the difference between sports pants and Casual pants?

1. Material:sports pants are usually used with breathable and sweat -absorbing materials, such as polyester, nylon, etc. to maintain the comfort during exercise, and Casual pants are usually cotton or blended materials, which is more suitable for daily casual wear.

2. design:sports pants are usually designed as loose cuts, which helps to provide greater activity space and flexibility, and facilitate activities during exercise.Casual pants pay more attention to comfort, often use straight or slightly loose design.

3. Function:sports pants usually have more functions, such as zipper pockets, ropes that adjust the waist circumference, zipper of pants feet, etc., which are convenient for stored mobile phones, keys and other items, and can be adjusted as needed.The function of Casual pants is relatively simple, and there are generally not many details.

2. Is Casual pants suitable for sports?

Some Casual pants may also have certain sports functions.Some Casual pants are used with light, soft and breathable materials, as well as the design of some sports elements to make them wear in mild sports or leisure activities.These pants may be more suitable for mild exercises, such as walking, jogging or simple outdoor activities.

However, if you need to do more severe exercise, such as Running, fitness or football, it is recommended to choose a specially designed sports pants.Professional sports pants can better meet exercise needs, provide better support, protection and comfort, while maintaining dry body and quickly discharge sweat.

In short, whether leisure pants are suitable for sports depends on specific styles and personal needs.If you only do mild or leisure activities, some Casual pants may be comfortable and practical.However, if it is more severe exercise, in order to better comfort and performance, it is recommended to choose a specially designed sports pants.

Astronomical Telescope eye mirror type Introduction of astronomical Telescope mirror structure diagram

1. Huachangs mirror (H)

The Dutch scientist Huachaus was designed in 1703. It is composed of two flat convex lenses. The front is a field mirror and the back is a mirror. Their convex surface is facing the end of the object mirror. The focal length of the field mirror is generally 2-3 times the mirror.It is half of their focal length.Huachangs mirror is about 25-40 degrees.In the past, the Huachangs mirror was the first choice of a small refraction mirror, but with the increase of the light power of the Telescope, the disadvantages of the obvious disadvantages of the field of view, low contrast, color difference, and ball differences. Therefore, this structure is generally generally generallyUse the eyepiece of the Microscope.

2. Romans Deng mirror (R)

The design was successful in 1783, and it was also two -sets and two groups of structures. It was composed of two flat convex lenses with the same focal length and the same focal length.The spacing is 2/3-3/4, which is the focal length of the two. The color difference is slightly large, and the field song is significantly reduced. The field of view is about 30-45 degrees. At present, it is rarely used.

3. Klena mirror (K, RKE)

It was developed on the basis of Ranzesden mirror. It appeared in 1849. The main improvement was to change the single -piece lighting mirror to the dual -glued color differential lens, which greatly improved the improvement of color difference and edge image.At 40-50 degrees, there is a comfortable pupil distance when it is low, so it is currently widely used in some low-dimensional Telescopes, but it is not well performed when it is high.In addition, the field mirror of the Kelna eye mirror is close to the focal plane, so that the dust on the field mirror is easy to images and affects observation, so pay special attention to cleaning.

A US company has further improved on the basis of Kylene mirror and developed RKE eyepiece. The edge image is better than the classic structure.

4. Abbey disorders (or) (or)

Designed by Abe, one of the founders of Germany's Zeiss Company in 1880, it is a structure of four pieces and two sets. Among them, the field mirror is a three -glue lens, and the mirror is a flat -convex lens.Like and the field of the field to the degree of difficulty, it also has a flat field of viewing and sufficient pupils at a flat field of 40-50 degrees. It has a good performance in each magnification and has been widely adopted.

5. Ailifer wide -angle mirror (ER)

The successful development in 1917 was designed for military Telescopes that needed a large field of view. It was the originator of all wide-angle mirrors. The structure was 5 pieces and three groups, and the field of view was as high as 60-75 degrees.It is very suitable for observing deep space celestial bodies. Because the edges are scattered, it is not suitable for high -power design. Its performance in low times is very good.

6. Prove mirror (PL)

Also known as symmetrical mirror.It is composed of the two sets of two sets of dual -gluing color differential lenses. Its parameter performance is equivalent to OL eyepiece, but it has a greater pupil distance and field of view. The cost is lower, and it is suitable for all the magnitudeThe eyepiece has been assigned a variety of improved types.

7. Nagler's eyepiece mirror

A high -end eyepiece designed by Americans in 1979 has an amazing field of 82 degrees, high -quality edges like quality and comfortable pupils, as well as complex structures and high prices, and weight of more than one kilogram.
