How many kinds of Nike shoes are there? According to what?

How many kinds of Nike shoes are there? According to what? . . . There are many brands. Simply put, brands are divided into Nike and Nike 360.

Just like Adidas and Adidas Clover. Footwear includes sports shoes and casual shoes, and the general category includes Nike DUNK SB.

AF 1 Nike is free. . Generally speaking, shoes are classified according to their efficacy, and then further classified according to different configurations, using different air cushions or just using ordinary damping glue.

There are several types of turning complex sentences. It's divided by tone. The meaning of the front clause and the back clause is opposite or relative, that is, the back clause does not follow the meaning of the front clause, and suddenly becomes a statement opposite or relative to the meaning of the front clause, and the back clause is the correct meaning that the speaker wants to express. According to the opposite meaning and relative degree of the clauses before and after, the turning relationship can be divided into three categories: heavy turning, light turning and weak turning.

First, turn again

The meaning between the clauses of the conversion relation is to give in first and then turn, and vice versa is of great significance, which is also called concession conversion. Retranslated conjunctions are common. The commonly used conjunctions are: "Although (although, although, although, although, of course) A, but (but, however, but still, also, and) B". For example:

Although the weather is so cold, I'm still sweating.

(2) Although Zhuge Liang said nothing, Xiao Erhei refused.

Although is more important than though. If "although" in Example 2 is replaced by "although", the tone will be much heavier. Another example is:

(3) Although many people say the same thing, there are still winners and losers in the fight.

Second, turn around gently.

The turning point of the light-to-light relationship means that the proportion is light, and the related words are used alone. The related words of light transfer are all single-use, and the commonly used related words are: "although, but, but, but, but, can, but".

For example:

Although there are eight big trucks, I don't think I can finish pulling them this afternoon.

Although the sparrow is small, it has all aspects.

She used to be a weak girl, but the wind knife of the years has hardened her character.

Third, the weak turn

The relative meaning between clauses of weak turning relation is often not so obvious, and the turning tone is weak, so only related words are used. Weakly transferred related words are all used singly, and commonly used related words are: "just, however, inverted".

For example:

7. In the end, he quit.

There is nothing special about the brothers, but they are straightforward.

He should have come, but he just had no time.

How many types of girls are there? According to what type and how to chase them? Generally speaking, there are only a few types of girls:

1, stubborn and arrogant. Chasing this type of girl must not be too gentle, just suitable. If you are too "nice", she will treat you as a servant and won't think much about your mood. She can stay with whoever she likes. But if you are a little hot and cold, she will think that you are a more elusive person, and will spend more time and energy to "study" you, so that you can inadvertently.

It will form a "two-person world" that is somewhat different from the original concept, so as to increase feelings.

2, gentle and sincere. This kind of girl is much easier to deal with As long as you are willing to "give generously" and give her gifts at Christmas, her birthday or other meaningful festivals, it will be enough to occupy her heart.

About 55.5% to 60%. Then after you are sure that she cares about you, you can make a plan, but not too angry, otherwise she will avoid you or even stay away from you because of shyness.

3, mild or super anthomaniac type. I'm afraid this kind of girl is rarely chased ... This requires you to generously take out the money in your wallet and passbook, go to the beauty salon to maintain your face, or go directly to the plastic surgery hospital to "check in" and buy a lot of high-quality and high-end clothes to decorate you. This is the fastest, fastest, fastest shortcut! But if you don't have financial resources, then you can chase after her slowly until you influence her with your heart and compare so many cool guys. I can't help but silently pray that you can have a better ending. .....

How many types of plastic runways are there? What are their characteristics, advantages and disadvantages? According to materials and construction methods, plastic runways can usually be divided into four types:

1, mixed plastic runway;

2. Breathable plastic runway;

3. Composite plastic runway;

4. All-plastic plastic track, etc.

The following are the functions and introductions of different plastics:

1, mixed plastic runway

Hybrid plastic runway, also known as traditional runway, has a flat and compact structure. Mixed plastic track is generally used in professional competition venues, which is a common type of middle and high-grade track and field venues, and its cost is much higher than that of breathable track and field venues. Our company's mixed runway adopts high-quality and environmentally-friendly special paving materials for two-component mixed runway, with a service life of 15 years, which has been recognized by many users because of its superior physical efficiency and good appearance quality. Requirements for foundation Requirements for foundation Requirements for foundation Requirements for foundation Asphalt foundation is recommended for mixed runway, and the foundation requires certain strength and stability. There should be no cracks or uneven frost heaving caused by freezing. In frozen areas, it is best to add a geotextile buffer layer between asphalt layer and gravel layer. The foundation along the sink should be particularly waterproof. The thickness of asphalt layer generally requires coarse asphalt 5 cm, fine asphalt 3 cm, flatness 3 m, straightedge error less than 3 mm, and the surface slope from the outer edge of runway to the inner edge (drainage ditch) is 6‰- 10‰, and it is recommended to reach 8‰. After rolling, the foundation density is more than 95%; The compaction density of subgrade graded sand layer is greater than 2.3kg/kg, the depth of heavy rolling wheel track is not greater than 5mm, the surface is smooth and solid, and there are no sand pits and plum blossoms. The density of gravel layer at the base is more than 2.3kg/kg, and the gravel is more than 2. 14kg/kg. The surface is solid and smooth, the gap is even, and there is no obvious re-rolling trace. The compaction density of black macadam layer of asphalt concrete is more than 97%, the dry bulk density is more than 2.35 kg/kg, and there is no oil stain on the surface, no unmixed asphalt blocks, no cracks, no obvious wheel tracks, no pushing edges, no loose pits, smooth joints and no water accumulation after the rain stops for half an hour. It is best to use asphalt materials containing no wax or less wax at the asphalt base, and the asphalt mixture must be fully compacted; Penetration110 mm >: 60, softening point >; 50oC, elongation 60cm. Compressive strength R20 & gt25 kg/cm2, R50 & gt25 kg/cm2, thermal stability coefficient Kt= R20/ R50≤3.5, and volume expansion rate.

Construction technology: the mixed plastic runway is laid by three-step construction method.

Acceptance of asphalt foundation. If there is a large gap on the surface of asphalt base, anti-seepage treatment should be carried out before paving. The impervious layer is formed by uniformly mixing component A and component B of a two-component mixed runway paving material in a specified proportion. Remember to add a proper amount of catalyst according to the change of temperature and humidity to form a mixed runway paving composite, add a proper amount of quartz sand for batch scraping and sealing, and wait for it to cure.

When the density and gap of asphalt base meet the requirements, the impervious layer may not be made, or after the impervious layer is completely cured, an appropriate amount of black rubber particles may be added to the evenly mixed aggregate according to the specified proportion, and the elastic layer with a thickness of 8-9 mm may be scraped in batches.

At present, there are two methods for anti-slip and wear-resistant surface layer: rubber particle spraying technology is to scrape the composite material with a thickness of 2 mm on the elastic layer, evenly sprinkle EPDM rubber particles or PU rubber particles by hand, sweep away the excess EPDM rubber particles that are not attached to the surface after curing, and finally spray a layer of reinforcing glue on it; The spraying process is to add an appropriate amount of EPDM particles to the sprayed fabric, stir it evenly, and spray it directly on the surface of the elastic layer with a special spraying device.

Use polyurethane marking paint to accurately measure the position of the process line according to the current standards of track and field facilities, and then spray it.

Breathable plastic runway

Features: Breathable runway, also known as seepage runway, is widely used in rainy areas because of its good air permeability and water permeability. Breathable runway not only has the advantages and efficiency of general runway, but also has low cost, and has become one of the mainstream products of plastic runway surface layer at present. The breathable runways produced by our company are generally laid by professional pavers, and the flatness is effectively controlled. In addition, the surface layer is sprayed by professional sprayers, and the content of polyurethane glue is very high. Therefore, compared with other types of runways, the fastness of the surface layer is higher, and maintenance is basically unnecessary during use, which greatly reduces the maintenance cost. The elastic layer of the breathable runway is paved with rubber particles crushed by recycled waste tires and other materials, which reduces "black pollution" and contributes to environmental protection.

Requirements for foundation: cement concrete foundation can be used for permeable runway, and the foundation should have certain strength and stability. There should be no cracks or uneven frost heaving caused by freezing. The stratum with high water content should be padded, and the foundation should be thickened or anti-frost heave measures should be taken in cold areas according to local geological conditions. Generally, the thickness of cement concrete should be around 120- 150mm, the flatness should be within 3 mm, and the strength should be above C20. The slope from the outer edge of the runway to the inner edge (drainage ditch) should be 6‰- 10‰, and it is recommended to be 8‰. Cement concrete should be slit every 6 meters, and it is recommended to slit every 4-5 meters. According to the standard curing period, the curing period of cement concrete is suggested to be 28 days. In the case of poor flatness, it is forbidden to make a layer of skin leveling with pure cement mortar, and it should be treated during surface construction.

Construction technology:

Brush one-component glue or primer evenly on the cement foundation with a roller brush.

Before the primer is cured, the one-component rubber and black rubber particles are mixed according to the specified proportion, fully stirred with a blender, transported to the paving place, and paved with a paver according to the specified thickness; After curing, it becomes an elastic layer.

Mix the breathable rubber spray with EPDM particles and EPDM powder in a specified proportion, stir evenly, pour into a special sprayer, and spray clockwise and counterclockwise for two or three times respectively. After curing, it becomes an anti-slip and wear-resistant layer. Now the commonly used colors are red and green.

Draw lines according to the rules of the game or the size required by users.

Acceptance methods and standards:

Physical properties meet the above standards.

Color: the colors of all regions should be basically uniform, and the multi-color runway should not be dazzling, which will not cause confusion in related competitions.

Surface quality: the surface material has no delamination, cracks, delamination and bulging. The thickness of the wear-resistant layer of the surface layer is not less than 2mm.

Smoothness: the error of 3-meter ruler at any position shall not exceed 3 mm.

Thickness: The thickness of the runway area must be within13mm 2mm, and the qualified rate is over 90%. Any position of the runway shall not be less than 9mm, and the thickened area (such as pole vault, javelin throw, long jump runway and high jump thickened area) shall be greater than 18mm. The thickness of the auxiliary area should be over 9mm.

Drainage: The runway should have a slope of about 8‰ from the outside to the inside, which can ensure that there is basically no water in the field for about 40 minutes after the rain.

3、

Composite plastic runway

Features: There are two kinds of compound runways. One is to lay 8-9mm elastic layer of breathable runway and 4-5mm EPDM rubber particles on the surface layer. Laying method is the same as elastic layer. This technology is simple in construction, but the surface layer is relatively flat, which is more suitable for the stadium and is generally not used. The other is the combination of breathable runway and mixed runway, that is, the runway composed of the elastic layer of breathable runway and the surface layer of mixed runway, which is generally suitable for the situation that the foundation is cement concrete and the surface layer requires mixing. The compound runway produced by our company not only ensures the stability of the combination of cement foundation and plastic bottom surface, reaches the national standard, is paved and sprayed mechanically, has excellent flatness and no threshing phenomenon, but also improves the grade of the surface layer, which is porous, breathable, breathable, excellent in elasticity and no foaming phenomenon. It can be used in all weather, with strong wear resistance, good weather resistance, strong compression resistance, good impact resistance and durability. The economical price provides more choices and lays a satisfactory runway for users.

Construction technology:

Brush one-component glue or primer evenly on the cement foundation with a roller brush;

Before the primer is cured, the one-component rubber and black rubber particles are mixed according to the specified proportion, fully stirred with a blender, transported to the paving place, and paved with a paver according to the specified thickness; After curing, it becomes an elastic layer.

Impervious layer construction: Mix the A and B components of the two-component mixed runway paving material according to the specified proportion, stir them evenly, and remember to add an appropriate amount of catalyst according to the change of temperature and humidity to form the mixed runway paving composite material, and add an appropriate amount of quartz sand, and scrape and seal the bottom in batches until curing.

At present, there are two methods for anti-slip and wear-resistant surface layer: rubber particle spraying technology is to scrape the composite material with a thickness of 2 mm on the elastic layer, evenly sprinkle EPDM rubber particles or PU rubber particles by hand, sweep away the excess EPDM rubber particles that are not attached to the surface after curing, and finally spray a layer of reinforcing glue on it; The spraying process is to add an appropriate amount of EPDM particles to the sprayed fabric, stir it evenly, and spray it directly on the surface of the elastic layer with a special spraying device.

Use polyurethane marking paint to accurately measure the position of the process line according to the current standards of track and field facilities, and then spray it.

Acceptance methods and standards:

Color: the colors of all regions should be basically uniform, and the multi-color runway should not be dazzling, which will not cause confusion in related competitions.

Surface quality: the surface material has no delamination, cracks, delamination and bulging.

Smoothness: the error of 3-meter ruler at any position shall not exceed 3 mm.

Thickness: The thickness of the runway area must be within13mm 2mm, and the qualified rate is over 90%. Any position of the runway shall not be less than 9mm, and the thickened area (such as pole vault, javelin throw, long jump runway and high jump thickened area) shall be greater than 18mm. The thickness of the auxiliary area should be over 9mm.

Drainage: The runway should have a slope of about 8‰ from the outside to the inside, which can ensure that there is basically no water in the field for about 40 minutes after the rain.

All-plastic runway

The characteristics, construction technology, technical parameters and acceptance method of the all-plastic plastic runway are exactly the same as those of the hybrid runway. The difference is that the elastic layer of the hybrid track is filled with no more than 25% black rubber particles, while the all-plastic track is not filled with black rubber particles.

According to the stress mechanism of column under vertical load, there are several types of beam hinge mechanism of column, that is, plastic hinge is at the beam end, and there is no plastic hinge at the column end except the column foot; The mechanism of column hinge refers to the formation of plastic hinges at the upper and lower ends of all columns in the same layer.

The reason why the beam hinge mechanism is superior to the column hinge mechanism is that the beam hinge is scattered in each layer, that is, the plastic deformation is scattered in each layer, so that it will not collapse, while the column hinge is concentrated in a certain layer, and the plastic deformation is concentrated in this layer, which is a weak layer or weak layer, leading to collapse;

The number of beam hinges is far more than that of column hinges. Under the same plastic deformation and energy consumption requirements, the plastic rotation ability of beam hinge is low, while that of column hinge is high.

Beam is a flexural member, which is easy to achieve great ductility and energy dissipation capacity. Columns are compression-bending members, especially columns with large axial compression ratio, which are not easy to achieve large ductility and energy dissipation capacity.

In practical engineering design, it is difficult to realize a complete beam hinge mechanism, which is often a mixed hinge mechanism with beam hinge and column hinge. In the design, it is necessary to delay the hinge of the column foot by increasing the bearing capacity of the fixed end section of the column foot; Through "strong column and weak beam", the column hinge is reduced as much as possible.

Crystal steel door panels are divided into several kinds of "crystal steel door panels", which means high efficiency door panels. At present, the main load-bearing body of crystal steel door is a new type of door panel material, with aluminum alloy as the skeleton and tempered glass covered with PVC. Generally, the glass is tempered glass with a thickness of 4mm, which gives a crystal clear feeling after surface treatment. The use of this plate has the characteristics of high strength, hard and smooth surface, light transmission, no peculiar smell, water resistance, high temperature resistance and scratch resistance. The outer edge is made of high-strength aluminum alloy profile with a thickness of 0.7mm, and the frame is made of ABS engineering plastic, which is durable and does not deform. Because the price is moderate, it is the new main force of cabinet door panel industry.
