fast variable meaning in Chinese

快变量

Bifurcation of homoclinicorbits in fast variable space
快变量空间中的同宿轨道分支
On the other hand , quite a number of practical systems with numerous dimensions may have some fast variables taking on singular impulse characteristic , such as electric power system , control system of rolling mill assembly , biochemical process , nuclear reactor , control system of airplane and rocket , and chemical diffused reaction , etc . so , it is important to study the problem of robust control of singular system i n the domain of control theory
一般这些不确定性并非不可度量的，通常能给出这些不确定性大小的某种约束，鲁棒控制理论正是处理系统模型具有不确定性的有效方法。另一方面，在大多数维数很大的实际系统中，都有呈现奇异摄动特性的快变变量，如电力系统，冷轧机的工业控制系统，生物化学过程，核反应堆，飞机和火箭系统，以及化学扩散反应等。
