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测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;第三对衰减振动的记录图提出了数据修正以提高测量程度;第四分析了微分标定法测U23可能出现的非线性失真以及避免的方法。
In this paper, the commonly used methods of calibrating the seismic system by the medium resistance are analyzed and some improvements are made to improve the accuracy and speed of the calibration work. Mainly, the first home-made high-precision measuring cycle meter to replace the artificial countdown meter measuring cycle method; the second with air damped monitor to quickly monitor the air damping to implement the assembly of the pickup condition; the third pair of attenuation vibration record The figure presents the data correction to improve the measurement degree. The fourth part analyzes the nonlinear distortion that the differential calibration method may appear and the method to avoid it.
