| 摘 要： | 本文着重论述了前后视标尺根值相等的水准测量原理：（1）前后视标尺所立之间相同时，前后视两点高差为：h=a-b。（2）前后视标尺所立之间相反时，前后视两点高差为：h=a-b-2i。a为后视标尺读数，b为前视标尺读数，i为尺根值。a,b,i均为有理数，其次证明了水准测量与转点标尺所立之间无关；与转点标尺的尺值无关。

| Abstract: | In this article, special emphasis is laid on level survey principle: (l) under same between forword sight and backsight staffs, height difference between two points-for- word sight and backsight h=a-b. (2) under contrary between two points-forword sight and backsight h=a-b-2i. a is the reading of backsight value. b is the reading of forword sight value. i is staff base value. a, b, i are rational numbers. The fact proves that level survey has nothing to do with turning point staff site and turning point staff value. |
