直读水准测量和直读水准尺及其应用

Direct-reading (of Elevation) Leveling and Direct-reading Rod and its Application

直读水准测量利用直读水准尺,可直接读出测点高程,特别适用于多中视点水准测量,可免去大量计算。此外,在水准导线测量中,直读尺亦可按传统尺操作,但计算公式中的正负符号应互换。

With the direct-reading leveling rod, direct-reading （of elevation） leveling technique can be applied to directly read out the elevation values of points. Especially for multi-intermediate sight leveling, lots of computation work can be avoided.
