查询词典 pendulum pump

The methods testing the WEP usually are torsion pendulum and free falling, the latter one is limited by the height of experiment, so the sensitivity of this method can't be improved, thus nowadays the torsion pendulum is mostly used in high sensitivity experiment.

检验弱等效原理的方法多为扭秤方案和自由落体方案，自由落体法由于受到实验高度的限制，使得在地球上的实验精度无法得到进一步提高，因此现在高精度的地面实验大都采用扭秤方案。
