第一类永动机指的是在不需要外界能量供给的前提下,持续不断的获取有用功的特殊机械。人们所说的永动机基本都是这种,为了制造出真正的永动机,许多杰出的人才都投入了大量的劳动和智慧。但是没有出现过任何一个真正意义上的永动机,所有关于永动机的设计都没有经受住科学检验,本文简要介绍了多种永动机,并且探讨了相关的启示。 The first type of perpetual motion machine refers to a special machine that continuously obtains useful work without requiring external energy supply. People say that perpetual motion motivation is basically the same. To create a true perpetual motion machine, many outstanding talents have invested a lot of labor and wisdom. However, there has not been any true perpetual motion. All the designs concerning perpetual motion have failed to stand the test of science. This paper briefly introduces a variety of perpetual motion machines and discusses relevant inspirations.
