| 摘 要： | 基于扭矩测量原理,设计了一个精度为1E的二维簧片重力梯度仪。它的敏感部分是一个簧片悬挂的二维Z形扭摆,用一个高灵敏度的二维电容微位移传感器来检测此摆的二维扭转情况,进而获得摆周围的重力梯度信息。该二维簧片重力梯度仪具有性能稳定、精度高等优点。

| Abstract: | A two-dimension gradiometer based on the principle of torsion measurement with a precision of 1E has been designed. It consists of Z-torsional pendulum as sensitive probe, and a two-dimension capacitive transducer is used to detect the signals in two directions at the same time and the two-dimension gradiometer parameters are gained. The instrument of new type will be applied to oil and mineral exploration with high measurement precision and stabile capability. |
