Through concretely analyzing the magnitude and error of deflection of the vertical, we can get the results that the long-period, smaller-range non-tidal variations are commonly less than the tidal ones, but the short-period, larger-range non-tidal variations are comparable to the tidal ones, especially in some areas they are even bigger than the tidal ones, this state can be measured by repeated gravimetry completely.

通过对垂线偏差量级和误差大小的具体分析，得出结论：一般长周期的、幅度较小的非潮汐变化要小于潮汐变化，但短周期的、幅度较大的非潮汐变化则可能与潮汐变化相当，个别地区甚至还会超过潮汐变化，这种情况完全可以用重复重力测量的方法检测到，这也说明重复测量的方法是可行的。
