Sales of its products include: LM series of precision rails, precision Ball Spline, precision ball screw and associated support components, precision cross-roller working platform, rail actuators, Zhixian Qiu Waterloo Block, guided packages, and various derivative - Spherical and even the axis of linear motion products such as grease.

其销售产品包括： LM系列精密导轨、精密滚珠花键、精密滚珠丝杆及配套支撑部件、精密交叉滚子工作平台、导轨引动器、直线球滑座、导套、导柱及各种球面连轴节和直线运动产品润滑脂等。

The ball 's redness and sphericity are ways it – that ball, and nothing else – is.

这个球的红色性和球形性是它所是的方式。

By this model, the formation of a spindle-shaped tip at the early stage of the ball forming process and the liquid metal wrapping around the solid copper wire tip can be explained, and thus the basis for controlling ball quality is established.

利用这一模型可以很好地解释铜丝在形球时产生纺棰形"尖刺"以及液态金属沿固态金属丝上衰的原因，从而为控制形球质量奠定了基础。

A strip block is used instead of the ball to eliminate the measurement error caused by the trajectory deviation of the ball when passing the photo gate.And a spring clip is used to replace the electromagnet to eliminate the effect of remanence.

在单摆法中，要求忽视细线的质量且线长及小球尺度相比很大，把小球看成质点，并且小球的摆幅不能超过5°[1~3]；在自由落体法中，一般是用小球作为自由落体，但小球通过光电门时，往往不是小球的质心遮光计时，另外，钢球是用电磁铁通电后吸住的，由于断电的瞬间，电磁铁有剩磁，钢球不立即下落，并且钢球应吸在电磁铁的中心处，这些因素都会影响重力加速度的测量。
