本文介绍的两套地震计是为电信传输地震台网配套设计的.目的是拾取周期较长、位移较大的地震信号.其特点是周期长,灵敏度高,多量程,稳定性好,结构紧凑,体积小.仪器采用了簧片轴承及零长弹簧.因而振幅-周期效应小,摆位-周期效应小.调试情况表明,长周期地震计要取得良好的性能,在很大程度上依赖于耐心细致的调整.记录情况表明地震计性能良好,符合设计要求.
The two seismometers introduced in this paper are designed for the transmission network of telecom transmission.The purpose of this paper is to pick up the seismic signals with longer period and larger displacements.They are characterized by long period, high sensitivity, multi-range, good stability and compact structure , Small size.The instrument uses a reed bearing and zero length spring.So amplitude - small period effect, set - cycle effect is small.Experiment shows that the long period seismometer to obtain good performance, largely depends on the Patience and meticulous adjustment.Recording shows that the seismometer performance is good, in line with the design requirements.
