1. Cascade control systems wherein the control loops are closed through a realtime network are called networked cascade control systems. 串级控制系统中，控制回路是通过实时网络闭合的，称为网络化串级控制系统。
2. Thyristor cascade control system is a low-cost system, but the traditional cascade control system has some shortages, such as a low power factor, serious harmonic pollution etc. 晶闸管串级调速系统是一种廉价、简易的调速系统，但是传统串调系统存在着诸如功率因数低、谐波污染严重等弊端。
3. A cavitation bubble in a cascade not only changes the flow field of the cascade, but also makes it difficult to calculate the flow field because of its unknown shape. 叶栅汽蚀绕流时所产生的汽穴不仅使流场发生了变化，而且其未知的形状使流场的求解变得十分困难。
4. The flow field of straight HP turbine cascade was investigated experimentally in a large-scale low-speed open-loop cascade heat transfer wind tunnel. 本文在大尺寸低速开式叶栅传热风洞中对一种高压涡轮导向叶栅中的流场进行了实验研究。
5. Points of knowledge: Multiple-stirred tank cascade, optimization of exit conversion; calculation of stirred tank cascade for isothermal in stationary state. 知识要点：多个全混流反应器串联，各反应器出口转化率的优化；定态下等温一级反应串联全混流反应器的计算。
