摘要
根据严格的数学推演给出涡流地震检波器电压的频率响应特性、阻尼因数、位相等的正确公式；定义表征其某些基本特征的物理量；讨论了文献［１］中某些严重错误，简介了我们研制的新型涡流地震检波器的某些性能。
The aim of this paper is to correct some mistaks in the theory of eddycurrent geophone,then enriches its contents and provides a right theoretical basis in orderto manufacture a new type of geophone. Firstly,it gives correct formulas for the nature of eddy current geophone′s frequencyresponse under electric pressure,damping coefficient and phase,by means ofmathematical reckoning.Secondly,it definites some physical gualities that show somebasic characters of geophone. Thirdly,it discusses some serious mistakes appeared in thethesis of Mr.E.M.Hall. Fourthly,it gives a brief introduction to some characteristics of the newest type ofgeophone being researched by us.
