Post Newtonian gravitycorrection to the acceleration of gravity in general relativity, produced by the sun and some planets, is calculated and discussed, and is compared with Newtonian tidal force.
计算和讨论了太阳和某些行星产生的广义相对论的后牛顿重力改正，并与牛顿引潮力进行了比较。

It has been verified by examples that the gravity used with Bouguer correction is enough accurate for atmospheric pressure measurement.
实例验证证明用布格修正法获得的重力值可以满足气压测量的准确度要求。

Through calculating, analysing and comparing the real data measured in two regions, indeed, it is proved that precision of gravity data after temperature correction increased somewhat.
