西北工业大学

本文考察了地震检波器寄生谐振的机理,对它进行了理论分析并给出实验研究结果。文中还介绍了为寄生谐振测试所采用的TR小型振动台。计算结果和实测结果都表明,振动台满足全部测试要求,且结构简单,测量精度可靠。

Based on the investigation for the machanism of the parasitic reso-annce in seismic geophone system, a theoretical analysis is made and the data resulted from some experiments are presented in this paper. In addition, a portable vibration table of mode TR used for these experiments is recommended. Both the conclusion derived from calculation and the result obtained from experiments show that such a table can meet the demand for various experiments and it is simple in configuration and reliable for measurement.
