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为后视标尺读生，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；与特点标尺的尺值无关。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.
