| 摘 要： | 本文研究确定冲击电压测量系统方波响应时间T_1时,实际方波的波前上升时间t_f对测量结果带来的影响.导出了一个简明的关系式:T_1=T0_+T_1.其中T_0为被测系统的真实响应时间,时间常数T_f跟t_f有关.讨论了该关系式的实际意义.文中还指出,电子技术中常用的波前时间累积公式不能用来计算上述误差.本研究结果易于估算由实际方波的波前带来的误差,可供实际使用.

| Abstract: | This paper describes an investigation into the influence of rise time t_f of a practical step on the determination of response time T_1 when the unit step response method is used for a high voltage impulse measuring system. The theoretical conclusion: T_1=T_1 + T_f has been obtained, where, T_0 is the response time of a measured system for a ideal unit step and T_f refers to t_f. Practical significance of the above conclusion is discussed. |
