要想保持温暧,想办法减少热量散失就好了。So easy!首先,揭开热量散失的秘密。那么,热量是怎么散失的呢?在冬季,辐射和对流散热是人体调节体温的重要方法。什么是对流散热?做个实验来了解一下。流动的烟雾你需要:两个一样大小的玻璃瓶,一截儿香,火柴或打火机,玻璃或塑料挡板。第一步:将一个玻璃瓶竖直放在热水中加热,将另一个玻璃瓶竖直放进冰水中(或放进冰箱冷藏室)变冷。 To keep warm, try to reduce heat loss just fine. So easy! First of all, uncover the secrets of heat loss. So, how heat is lost? In the winter, radiation and convection heat dissipation is an important method of body temperature regulation. What is convection heat? Let’s experiment to understand. You need: two glass bottles of the same size, a half stick of incense, matches or lighters, glass or plastic bezels. The first step: a glass bottle placed in hot water vertical heating, another glass into the ice water vertically (or into the refrigerator freezer) to cool.
