在第二次工业革命中,我们人力发明了电力,因此电力的发明与推广应用对我们人类产生了广泛的影响,其改变了我们人类生产、生活条件。而电力工业经过一个多世纪的发展,人类对其依赖性并没有因为时间而减弱,反而对电力的依赖性越来越强,基本上成为我们人类生产、生活中所必须应用的。所以,我们今天就以电力为线索,来展开研究与探索。 In the second industrial revolution, we invented electricity by manpower. Therefore, the invention and promotion of electricity have a widespread impact on our humankind, which has changed our human production and living conditions. After more than a century of development in the power industry, human dependence on it has not been weakened by time. Instead, the power industry has become more and more dependent on electricity and basically has to be applied in our production and life. Therefore, we are today using electricity as a clue to carry out research and exploration.
