| 摘 要： | 本文討論了一套配合現成示波器进行地震波模型試驗用的电子线路。綫路的前置放大器的通頻带为2-700千周,增益为60分貝,輸入端短路噪声电压为2.5微伏.高压脉冲发生器产生一个寬度为2-33微秒的幅度为500伏的矩形电脉冲。时标电路产生2,10,50微秒三組吋标,基本吋标（2微秒）可由稳定的石英振蕩器随时加以校准。整个线路此較簡单、灵活,一般地球物理实驗室試制容易,且可根据具体要求加以变动。

| Abstract: | The present paper describes a portable and simple electronic circuit, which when incorporated with a pulse cathode ray oscillograph can be used in an ordinary seismic wave model experiment. The preamplifier has a pass band of 2-700 K.C., with amplification of 60 decibels. The noise level is about 2.5 micro-volts when the input terminals are short-circuited. The pulse generater produces an output pulse of 500 volts with varible time durations from 2 to 33 micro-seconds. The instrument includes three kinds of time scales with time intervals of 2, 10 and 50 micro-seconds respectively and the one with time interval of 2 μ.S. can be calibrated with a stable quarty oscillator installed inside the instrument. |
