由于杠杆百分表使用方便,又具有相当的精度,所以被广泛地应用于工厂车间。它的测量杆可以作180°的摆动,这给测量各种形状的零件带来很大方便。但也由于它可以任意摆动,往往被工人误认为量杆随便怎么摆都可以。黄尧同志提出了这个问题,是很必要的。本文试图推导杠杆百分表量值的修正系数,以便工人在使用此类百分表时修正之用,使之获得正确的测量结果。
Because the dial indicator is easy to use, but also has considerable accuracy, it is widely used in the factory floor. Its measuring rod can be swiveled by 180 °, which gives great convenience to measuring various shapes of parts. But also because it can be arbitrary swing, often mistaken for workers to measure the amount of rod can be placed anywhere. It is very necessary for Comrade Huang Yao to raise this issue. This article attempts to derive a correction factor for the amount of leveraged dial indicator so that workers can correct the use of such dial indicator to get the correct measurement result.
