摘要
测量误差是否遵从正态分布律一直是测量学者关心的问题。本文对水准测量往返测之差值收集了210个子样,应用数理统计的方法进行检验分析,结果说明水准测量闭合差基本符合正态分布律。
Whether error of measurement is obedient to normal distribution has long been concerned. In the practical working, writer of this article collected 210 subsamples and verified the difference of to and fro measurement with mathematical statistics method. The result showed that error of closure of level obeys normal distribution on the whole.
