检波器尾锥长度浅析

Briefly analyzing length of tail cone of geophone

已有的三分量检波器在尾锥与地表紧耦合条件下，无法调节方位角及倾角。

For there is three spikes on three-component geophone , current type of geophone cannot adjust azimuth and inclination in the condition of tight coupling between earth and spike , so there is serious fault in it .

因此，在准备为我的平方东西放在桌上，用激光水平，并提出了提高磁带线，使国宝可以切断苯乙烯尾锥，使树脂浇注的一部分。

So in preparation for that I squared things up on the table , used a laser level and made a raised tape line so David can cut off the styrene tail cone and make the cast resin part .

结合工程实践中的传感器安装固定方式，通过理论模型论证了检波器附加质量、接地弹性支撑系数、检波器尾锥长度等给检波器的幅频特性或相频特性带来的改造或歪曲；

In combination with the installing style of sensors in practical projects , the influences of the additional mass , the grounding elastic support coefficient , and the tail length of sensors on their amplitude-frequency characteristic and phase-frequency characteristic were demonstrated with the theoretical model .
