动力是現代工业的血液。沒有动力机器会停止轉动,工厂要停工,一切現代化设施都将失掉作用。解决动力問題,首先需要获得能源。人們已經从煤、石油、天然气等燃料,以及日光、風力、河流、潮汐取得热能和电能。但是,地球上的燃料不是取之不尽,用之不竭的。按照目前人类消耗动力的速度及預計的增长速度来推断,二百年左右将用尽地球上所儲藏的煤、石油、森林和其它燃料鞘比藗兘幽睦锘袢∪饶苣?于是,地下热能的开发和利用,就越来越引起科学家們的注意了。
Power is the blood of modern industry. Without power the machine will stop spinning, the factory will be down and all modern facilities will be out of action. To solve the motivation problem, we must first get energy. People have harvested heat and electricity from coal, oil, gas and other fuels, as well as sunlight, wind, rivers and tides. However, the fuel on Earth is not inexhaustible. According to the present rate of human consumption and the expected rate of growth, it is estimated that in about two hundred years the coal, oil, forests and other fuel stored on the earth will be exhausted more than 藗 兘 于 锘 ∪ ∪ 饶 Chicory so , The development and utilization of underground thermal energy have drawn more and more scientists’ attention.
