一种多功能静电演示实验仪的研制与使用

The Development of a Kind of Multi-functional Electrostatic Demonstrating Apparatus

所设计的一种多功能试验仪，应用负离子发生器产生的高压作为电源，可以实现静电除尘模拟、跨步电压模拟、尖端放电演示、内燃机点火系统模拟等实验，且其本身还可作为负离子发生器，从而达到一仪多用的目的．

A new kind of multi-functional demonstrating apparatus is introduced in this paper. Using the high voltage which is produced by this generator as power supply, many simulating experiments such as electrostatic precipitation, step voltage, point discharge and ignition system for internal combustion engine might be performed. Plus its function as a negative ion generator, this apparatus is multi-functional.
