1. These turn on a vertical axis with the water entering through a spiral casing and then inward through adjustable “gates”(i.e., valves) to a “runner”(i.e., turbine wheel) with fixed blades.这些水轮机靠立式轴旋转，水流通过螺旋状通道和一个可调的阀门向内流向带有固定叶片的涡轮。

2. In this scheme water is pumped from a lower reservoir to a higher one during off-peak times (generally at night) and the water is allowed to flow downhill in the conventional hydroelectric mode during times of peak demand.在这种系统中，非高峰负荷期间（通常是夜间）水被从低处的水库抽到高处的水库，而在高峰负荷期间水流按通常的水力发电模式从高处流下来。

3. In a sense, from the point of view of the thermal part of the system, the pumped storage scheme “shaves the peaks” and “fills the troughs” of the daily load-demand curve.从系统热力发电部分的角度来看，在某种意义上抽水蓄能电站的运行时对日负荷曲线进行“削峰”和“填谷”。

NotesNotes

1. In USA, the two common types, collectively called light-water reactors (to distinguish them from a type using “heavy water”), are the boiling-water reactor(BWR) and the pressured-water reactor(PWR), and both use water as coolant.在美国，使用着两种反应堆：沸水反应堆（ BWR ），压水反应堆（ PWR ），两者统称为轻水反应堆（区别于“重水” 反应堆），并且都是使用水作为冷却剂。
