测震系统标定的改进

本文对常用的通过测中肯电阻标定测震系统的方法进行了分析并提出了改进，以期提高标定工作的精度和速度。主要有，第一用自制的高精度周期仪代替人工读秒表的测周期方法；第二用空气阻尼监测仪快速地监测空气阻尼以落实拾震器的装配状况；第二对衰减振动的记录图提出了数据修正以提高测量程度。

Improvements in the Adjustment of Telemetric Seismic Network of Chengdu

With the analysis of the adjustment of telemetric seismic network, we made some improvements on the method of measuring the medium resistance to increase speed and exactness of adjustment. First, the period error is decreased by using the periodic instrument instead of using stopwatch. Second, the air damping value is measured by using the air dampingmeter to test the state of seismic geophone. Third, the correcting data of attenuate oscillationis introduced. Last, it is important to avoid the nonlinear distortion.
