, 1988 本文在作者提出的电探针测定稳态等离子体电子能量分布方法(二阶微分网络法)基础上,结合连续脉冲扫描,实现了对脉冲等离子体探针电流对电压二阶导数曲线的连续测量。每条曲线测定时间20～30μs,测量间隔211μs。此方法可用来测定脉冲放电过程中的电子能量分布及其随时间的变化。本文还提出可用惰性气体亚稳态的Penning 电离来标定EED ...

Gaoya dianqi为研究IEEE模型和Pinceti模型对金属氧化物压敏电阻（metal-oxide varistor，MOV）的仿真准确性，以额定电压为150～750 V的6种MOV为对象，理论和试验分析了不同幅值4/10 μs、8/20 μs雷电冲击电流和30/60 μs操作冲击电流下的残压及吸收能量。结果表明，在IEEE模型参数确定中，随操作冲击电流幅值的增大，非线性电阻参考电压取值增大但电感取值减小；在残压预测中，IEEE模型误差为2.6%，较Pinceti模型误差4.6%更准确；在MOV吸收能量估算中 ...
