摘要
从分析光学测微器的工作原理入手,总结出精密水准测量的读数中有常差的存在,进而分析出当水准尺倒立时,存在读数的两步化算问题,从而解决了出现水准尺倒立时的高差计算问题。
Analysis of optical micrometer start with me working principles,summed up the precision measurement standards are often poor readings in the presence of further analysis of the standard - foot inverted, the existence of the two-step cost - reading problems, so as to solve the emerging standards the inverted- foot elevation difference calculation.
