It is important to note that the sticking force is a product of the differential pressure between the wellbore and the reservoir and the area that the differential pressure is acting upon.

注意到以下这一点很重要：即卡钻力是井内流体压力与地层压力之差与此压差所作用的面积的乘积。

The response characteristics of wrist force sensor determined the sticking of sensor's strain gauge and sensor's orientation method and also affected the dynamic characteristics of robot system.

腕力传感器的响应特性决定了传感器应变片的粘贴和传感器的标定方法，也影响机器人系统的动态特性。
