摘要
从观测思路、测点偏离值与位移量计算公式推导、精度分析等几方面阐述了小角法在长度不同的视准线观测中的灵活运用。
This article elaborate on the application in a flexible way of small angle measurement in the varying collimation line observation of length,which from observational thoughts／／ deviation value of measuring point／／equation derivation to calculate the displacement and precision analysis etc.
