摘　　要：介绍了电阻、电容器、二极管等电学原件的特点、各情况下电路的测量原理以及电学黑箱中电子元件或电路情况的判断方法．提出了用万用表测量三角形黑箱和直线型黑箱的实验方法．Electrical black box refers to a system containing a variety of electrical components in the unknown, do not open and not to damage the structure of the case, to study its internal structure through experiment. Electric detection of ＂black box＂ problem is complex and flexible, to solve this problem starting from the basic characteristics and the measurement principle element, therefore need to understand the characteristics of various electrical components and more accurate measurement.
