本文所讨论的是有关热的辐射、吸收与物体表面的颜色的关系问题.表面黑色粗糙的物体吸收辐射本领大,表面浅色光亮的物体吸收辐射本领小.因而大多数物理教师都简单地认为夏天穿浅色衣服凉快,冬天穿深色衣服暖和.果真如此吗?非也!穿什么颜色的衣服凉还是暖取决于衣服是吸热还是放热,而物体是吸热还是放热(辐射热)又取决于衣服与外界的温度以及外界热辐强度两个因素.冬天,气温低、体温高,服装的温度介于两 This article discusses the relationship between thermal radiation, absorption and the color of the surface of the object. The surface of the black rough object absorbs large amounts of radiation, the surface of the light-colored objects absorb radiation skills. Therefore most physics teachers simply think Summer wears light-colored clothes to cool, winter wears dark clothes for warmth. If so, why not? What color of clothes to wear is cool or warm depending on whether the clothes are endothermic or exothermic, and whether the object is endothermic or exothermic (radiant heat) ) It depends on the temperature of the clothes and the outside world and the heat intensity of the outside world. In winter, the temperature is low, the body temperature is high, and the temperature of the clothing is between two.
