几种水准测量方法在电子直线加速器测量中的应用

Application of Some Level methods in LINAC Measurement

分析现有各种水准测量方法的特点,结合电子直线加速器的测量实践,提出短距水准测量的概念。通过比较常规水准仪四次不同测量和激光跟踪仪测量的结果,分析各种测量仪器和方法的精度,指出短距时光学水准仪、电子水准仪、激光跟踪仪的高差测量精度相当,但激光跟踪仪高差可能存在系统误差。

This paper analyzes the character of several level methods and brings forward the concept of short-distance leveling according to the measurement practice of LINAC. Comparing the results from four time's normal level instrument measurements with that from Laser Tracker and calculating the accuracy of the instruments and methods and putting forward the high difference measurement accuracy of digital level, optical level and Laser Tracker are the same for short-distance leveling, but the high difference of Laser Tracker may contain some systematic error.
