摘　　要：介绍了一种脉冲放电弧光等离子体演示仪.该设备内置的测量电路可以直接显示放电电压、电流的大小和放电的持续时间,放电电流也可以通过附带的感应线圈来测量;结合光栅光谱仪,可以测出发光光谱,进而求出等离子体的温度、密度等参数.A demonstration device for pulsed discharge arc plasma is introduced. With built-in electronics, the device can display the discharge voltage, current and duration time. The discharge current can also be measured by an induction coil. The optical errlission spectrum is measured with a grating spectrometer. The temperature and density of the arc plasma can be calculated from the obtained spectrum.
