Audio failures are generally divided into two categories: one is caused by improper use, and the other is caused by the weather. Now most new cars are equipped with CD equipment, the main factors affecting the normal work of car audio in late summer and early autumn are high temperature and humidity. Because the car audio is mostly installed in the upper part of the dashboard, in order to avoid the exposure of the sun, the effect of using sunshade is better. If the door and window sealing strip is not strict, it should be replaced, otherwise the loudspeaker is easy to rust and damage, or even cause short circuit to burn the main engine. With the coming of the rainy season, the humidity increases, and there is often a layer of fog on the surface of CD records, which makes it difficult to read the disc. It is best to scrub it every once in a while. If the CD drive is modified, in order to avoid dampness, do not install it under the floor and seat, preferably on the high part of the car body, but not on the rear windshield, too high temperature will accelerate the aging of electronic components and laser head.
In the design and development of interior fabric, we often use fiber materials with fine denier and high hole to reduce the rigidity of the fiber and increase the soft touch of the fabric. at the same time, we can also use different yarn shrinkage to achieve the shrinkage elasticity and thick feeling of the fabric; in order to ensure the straightness of the sunshade fabric, we need to stiffen the fabric. In order to increase the friction coefficient of the seat synthetic leather surface, we choose the surface embossed texture with a strong sense of particles; in the coating of the dashboard or door panel area, in order to meet the delicate comfort in the process of use, we often use fine frosted texture and matte gloss treatment at the same time.
The exterior sunshade of the building is specially designed, which fully considers the difference between summer and winter, meets the enhanced shading performance in summer and the enhanced heat performance in winter, and greatly reduces the energy consumption of air conditioning and heating in the whole year. Figure 1 shows the exterior sunshade used in the building. The whole building adopts non-thermal bridge design, and the thermal bridge coefficient ψ a ≤ 0.01W/ (m ·K). Figure 2 is a simulation diagram of the temperature distribution of the thermal insulation effect of the peripheral structure nodes.

Jingzhou customized internal and external sunshade fan water curtain multi-span greenhouse, please check more, when it snows, snow will inevitably bring temperature drop, prepare grass cloak and other thermal insulation items and auxiliary heating equipment such as furnace in advance, in order to supplement the indoor temperature of greenhouse and prevent frostbite. Clear the snow in time after snow has accumulated to a certain thickness or after the snow stops, pay special attention to strengthening the snow removal work at night, the preventive measures at night generally can not keep up with the changes, and the snow cover should be avoided from collapsing the greenhouse and greenhouse. Causing unnecessary losses. After heavy snow, it should be ventilated in time during the day after the weather clears up, but the vents should be properly handled and should not be opened too wide to prevent sudden heat or cold inside the greenhouse from affecting vegetables.
