机械误差 meaning in English

imperfection
machine error
mechanical errors

Since precise mechanical tolerance is difficult to maintain over a long shaft, pulling with a cable may be necessary .
因为过长的拉杆很难保证精确的机械误差，故可以用缆索。
Grating - sensory technology of original creation - eliminating the mechanical error in sensory system
检测系统独创的光栅传感技术，使机械误差近似于零。
After ameliorate the hardware of the spectrometer , there are many kinds of noise added to the system inevitably . they are hot - noise and disperse - noise in electron circuitry and the wavelength excursion due to the grating turning
光谱仪经过硬件改造以后，不可避免地将电子方面的噪声带入到系统中，其中主要包括电子线路中的热噪声和散粒噪声（白噪声）以及光栅转动过程中的机械误差引起的波长漂移。
Theoretically , we can calculate the transfer matrix between cube frame and robot - tool frame , because the relative position between marker cube and guiding robot is fixed . but error of mechanical interface is too serious to accomplish locking hole . we solve this problem by using neural net
针对导航机器人的标定盒与机器人之间存在加工和安装尺寸误差,导致标定盒坐标系与机器人工具坐标系之间坐标转换不准确的问题,采用神经网络方法建立坐标转换模型,从而规避了标定盒与机器人接口的机械误差问题,实现两坐标系之间的转换。
