摘　　要：从动圈式地震检波器频率响应的数学模型分析了振动法测量其频率响应的原理,并指出测量过程中的注意事项。作者测试了两种国内地震勘探作业中广泛使用的检波器并对测试结果的误差进行了分析,为评价检波器的性能提供一定的参考。On the basis of the Mathematical model of the moving coil geophone's frequency response,this article discusses the measuring principle of geophone's frequency response by using the law of vibration and furthermore it points out precautions during the testing process.The author tests two commonly-used geophone of seismic exploration in China and finishes the error analysis of the test results.This paper may offer some helpful references for users' evaluation of the performance of geophones.
