一、引言 在生产斗争和科学试验领域内,如大型机组主轴的安装、大坝变形观测、导弹及飞机的装配、直线加速器的准直等等,往往要求在数米范围内对准精度须小于1丝米,或者在数百米以至几公里的距离内对准精度须

I. INTRODUCTION In the fields of production struggle and scientific experiments, such as installation of main shaft of large units, deformation observation of a dam, assembly of missiles and aircraft, collimation of a linear accelerator, etc., often require that the alignment accuracy within a few meters should be less than 1 silk, or within a few hundred meters and even a few kilometers away from the accuracy of the required
