亲爱的读者们,你们知道什么是地热吗?地热就是地球内部的热量。有的同学可能会说:地球不就是一个硬邦邦的大球吗?再说了,我们脚下的大地从来都是冷冰冰的,哪有什么热量!这样想的同学还真是不少。因为他们不了解,我们脚下的地球可是一个外冷内热的特珠大球,越往地球里面,温度越高,等到了几千米,地球里已经成了巨大的能量库,但达到一定深度后越往里地下温度越低。这种能量,就是地热!而一天从地球里面穿到地面的地热,就相当于全人类一天使用能量的2.5倍! 由于现在的煤炭和石油越来越少了,地热能源就显得越来越重要。我们这期要介绍的科学家呀,就是研究地热资源的中科院院士——汪集旸爷爷。汪爷爷从小就羡慕那些在野外整天考察的地质科学工作者,认为整天可以游山玩水,多好!瞧瞧,汪爷爷小时候是一个很贪玩的小孩呢!走,让我们到汪爷爷的小时候看看去!
Dear readers, do you know what is geothermal? Geothermal is the heat inside the earth. Some students may say: Is not the earth a big ball? Besides, the earth under our feet is always cold and what kind of heat is there! There are quite a few classmates who think so. Because they do not understand, the earth under our feet is a special big ball of external heat and heat. As the temperature goes higher and reaches a few kilometers, Earth has become a huge energy reservoir. However, after reaching a certain depth The lower the temperature the more underground. This energy is geothermal! One day the heat that is applied to the earth from the earth is equivalent to 2.5 times the energy used by all mankind a day. Due to the current coal and oil less and less, geothermal energy becomes more and more important . The scientists we are going to introduce this issue are the academicians of the Chinese Academy of Sciences who are studying geothermal resources - Wang Jiji 旸 grandpa. Grandpa Wang envy those geoscientific workers in the field all day long study, that all day can be a sightseeing tour, how good! Look, Wang grandfather was a very fun kid it! Walk, let’s go to Wang Grandpa’s childhood look to go!
