The control object in a single-freedom silicon micromachined vibratory gyroscope is the proof mass, because of system structure, feedback control is the only choice to control the proof mass.
以单自由度硅微振动轮式陀螺仪的检测动极板为控制对象，系统的结构特性决定了只能选择反馈控制方式对其进行控制。
The principle of accelerometer is based on the measurement of the relative displacement that arises between the elastically suspended proof mass and the accelerometer frame subject to acceleration.
加速度计是靠感测因惯性力引起的相对位移来测量视加速度的，不能测量真实的重力加速度。
And not just one study, as no one study will be proof of anything - show me the mass of research that's been done.
并且不是一个研究，因为没有人的研究能证明一切事情——请给我展示已经完成的大量研究成果。
