Since the leakage current through the zener diodes results in a voltage drop across the resistor, low leakage zener devices are desirable. 由于流过齐纳二极管的泄漏电流会在电阻器上产生电压降，所以希望使用低漏电的齐纳二极管。
Each relay driver is an open - collector transistor with a suppression diode. 每一个中继驱动器是一个集电极开环的三极管和一个稳压二极管。
Client software development is introduced with the example of zener diode tester software design, and multiple threads technology is explained emphatically. 以稳压二极管测试仪的软件开发为例介绍了客户端的软件开发，着重介绍了多线程技术的应用。
