DSL—1型流动地震仪是一种多用途微震仪,近年来国内已广泛地应用于天然地震、人工爆破、地面脉动以及工程振动测量等方面。本文详细研究了该系统的动态特性并给出它的解析计算式,以便于对观测波形作定量分析使用。文中还描述对该系统进行的测试研究。结果表明,本文的系统动态特性的理论结果与实验测定吻合良好。
DSL-1 mobile seismograph is a multi-purpose microseismometer, which has been widely used in natural earthquake, artificial blasting, ground pulsation and engineering vibration measurement in recent years. In this paper, the dynamic characteristics of the system are studied in detail and its analytic formula is given to facilitate the quantitative analysis of the observed waveforms. The article also describes the test conducted on the system. The results show that the theoretical results of this paper are in good agreement with the experimental ones.
