According to the low orbit altitude and the geometric model of the satellite, we have designed a radio frequency permeable sunshade for the satellite, which can prevent light from reaching all the diffuse parts of most satellite bodies and bodies. The visor is laid flat on the chassis during launch and unfolded during satellite separation from Falcon 9. The sunscreen completely blocks the light from reaching the antenna, thus preventing the light from being reflected from the diffuse antenna. This method not only avoids the thermal effect of the darkening of the antenna surface, but also has a greater impact on the brightness reduction. As mentioned earlier, the first VisorSat prototype was launched with the eighth batch of star chains, and we will install these black mirror sunshades on all satellites after June.
The internal thermal insulation system can be divided into the top and the side, and the principle is to reduce the heat loss in the shed by arranging automatically contractible thermal insulation curtains on the top and side parts, so as to achieve the effect of thermal insulation. At the same time, after the expansion of the internal thermal insulation system, the moisture in the shed is isolated so as to reduce the role of condensed water on the roof. Like the sunshade system, the top internal thermal insulation system is closed by aluminum alloy moving edge, deceleration motor, transmission rack and hot-dip galvanized push-pull rod.
In a typical dialysis clinic, there is no guarantee that all the spaces frequently used by patient stations or staff will have natural lighting. The direction of the glass usually causes glare and may not be consistent with the comfort and safety of the patient. The project consists of two indoor courtyards that provide fair access to daylight throughout the clinic, while allowing other use spaces, such as offices, conference rooms, staff lounges and private family training rooms, to benefit from outdoor vision and adequate natural light. In order to reduce the increase in glare and solar heat, the design gives priority to north-south glass, using building mass and sunshades and custom perforated vertical screens to regulate direct sunlight in the south.
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. The specific heat of the circuit board and plastic components in the car audio mainframe is different, so it is affected by the temperature change to a different extent. In the scorching sun, it is best to use the sunscreen to ward off the scorching sun and avoid the direct sunlight.
In the part of storage space, both cars are fully equipped. In addition to conventional front and rear door slots, glove boxes, armboxes, storage compartments and cup holders under the center console, a lot of hidden spaces are optimized, such as the storage space above and below the sub dashboard of BYD Song PLUSDM-i, under the left air conditioning controller and inside the sunshade. The Harvard second-generation dog PHEV is also equipped with more user-friendly storage space, such as four-door cup holder straps, storage slot above the glove box, upper and lower two-story temperature control armrest and multi-stage lifting cup holder.
To travel, bags are very important! Most people will choose a suitcase or a light backpack. Punching in tourist attractions must also need another bag. If you want to be comfortable, the backpack is the most comfortable. You can also prepare a small waist bag, shoulder bag for documents, mobile phones and other small items. Shandong Taigang Mathematical Group recommends that you prepare larger bags, including sunny umbrellas, sunglasses, sunshade hats, paper towels and mobile power supplies.
