It is not quite correct that quickness of a servo system having power saturationcharacteristics is judged by evaluating only the bandwidth.
由于功率饱和的影响，只用“频带概念”来衡量随动系统的快速性是不够确切的。
2
The saturationcharacteristics widely exists in almost all kinds of control systems, such as chemical plants, mechanical systems, and communication networks.
饱和特性广泛地存在于各类物理系统中，比如化学装置、机械系统、以及网络通讯系统等。
3
The sensitive temperature characteristics of PN junction inverse saturation current is fully utilized to obtain good temperature coefficient and PSRR with simple circuit structure.
