For an impulse source there shall be a peak reading instrument voltmeter connected directly to the electrode head, indicating continually the potential of the electrode with or without a grounded test wire in the chamber. 脉冲火花机,电压表直接接在试验电极上,显示的是测试电线没有接地的情况下的峰值电压。
Development of Impulse Peak Voltmeter 新型冲击峰值电压表的研制
The peak stresses of various cycles were measured by a digit voltmeter and the stress-strain hysteresis loops for selected cycles were recorded using an X-Y recorder. The energy losses, friction stresses, back stresses and shape parameters of hysteresis loops were measured from the hysteresis loops obtained. 记录了各循环周次的应力、应力-应变滞后回线,根据回线的面积和形状计算了循环形变中的能量损耗、摩擦应力、反馈应力及形状参量。
