摘要
本文利用887个测站上的 koni007和 Ni004仪器观测数据,以高差的绝对值之差作为统计子样,分别按总体、各测段、上坡、下坡和方位进行分类。采用数理统计方法对数据进行检验分析。作者认为 koni007和 Ni004仪器所测结果在一定条件下存在差异,并对差异的原因作了讨论.
The 887 data obtained at the same time with the leveling instrument Koni007 and Ni004 are used to test if the differences exist in leveling data.Using statistical methods,data are divided into five groups according to whole, uphill,downhill,direction and segment between two leveling Points.The test results of these data indicate that there is a difference when the direction is about nouth-south.This Paper also gives some explanations to the difference between two kinds of instruments.
