天气热了,大家都喜欢穿浅色的衣服,尤其是白色的衣服。因为很多人都觉得夏天穿浅色衣服凉快,而深色的衣服吸热快,在太阳下晒一会儿,表面摸上去就很热了。不过,美国哈佛大学曾经做过一项实验研究,结果表明,在炎热的夏季,穿深色服装比穿白色服装凉爽。专家们指出,人体内的热量可以通过辐射、传导、对流和蒸发向外散发。诚然,黑色衣服比白色衣服吸热多,但吸收的热量可以成为衣服内形成对流的动力(就像夏季的午后,地面受热容易形成局地对流天气,比如雷阵雨天 The weather is hot, we all like to wear light-colored clothes, especially white clothes. Because many people find it cool to wear light-colored clothes in the summer, and the dark clothes are fast-absorbing, they are sun-dried for a while and the surface feels very hot. However, Harvard University in the United States had conducted an experimental study, the results show that in the hot summer wear dark clothing cooler than wearing white clothing. Experts point out that the body’s heat can be emitted by radiation, conduction, convection and evaporation outward. Admittedly, black clothes absorb more heat than white clothes, but the absorbed heat can act as a convective force in the garment (just as in the summer afternoon, the ground is heated and convective weather easily occurs, such as thunderstorms
