正如其它资源一样,以前一度被简单地认为是无限能源的水,现在同样被认为是有限的了。这就是说,水的供应是有限的。全世界的电力发电当局现在所考虑的问题,是用改进现有发电厂的效率,来更有效地使用这种有限的资源。这篇论文的目的,就是讨论一种选择水力发电最佳特性方法,这就是水轮机效率的快速测量。 Just like any other resource, water, once considered simply as infinite energy, is now also considered limited. This means that the supply of water is limited. The issue now considered by power generation authorities around the world is to make more efficient use of this limited resource by improving the efficiency of existing power plants. The purpose of this paper is to discuss a method of selecting the best characteristics of hydropower, which is a quick measure of turbine efficiency.
