想一想你知道民航客机为什么是银白色的吗?科学关键词温度原来如此因为客机需要长时间在空中飞行,在高空高速飞行的过程中跟空气的摩擦会产生高热,并且它还受到阳光的直接照射,所以需要反射掉一部分阳光才能降低温度,而银白色反射效果很好。此外,飞机使用铝合金制造能减轻重量,而铝合金的颜色就是银白色,如果上色就会增加重量,所以飞机一般保持银白色。不过,现在的飞机根据自身的需要,也会对飞机的颜色进行调整。其他国家的飞机很少见有白色的,比如美国的飞机涂装就是蓝灰色的,至 Think of it Why do you know civil aviation airliner is silver white? The scientific temperature of the original words because the aircraft need to fly in the air for a long time, in the high-altitude high-speed flight friction with the air will produce high fever, and it also sunshine Direct exposure, so you need to reflect part of the sun to reduce the temperature, while silver white reflection is very good. In addition, the aircraft made of aluminum alloy to reduce weight, while the color of aluminum alloy is silver white, if the color will increase the weight, so the aircraft generally remain silver. However, the current aircraft according to their own needs, but also the color of the aircraft to be adjusted. Planes in other countries rarely seen in white, such as the United States aircraft coating is blue-gray to
