摘　　要：测程是全站仪重要技术指标之一,本文从相位式测距仪的测程公式出发,探讨了在短基线或短距离上进行测程检测的原理和方法,为中、长程全站仪的测程检验提供了可能性。这种检验方法是在短基线或短距离上用改变反射镜有效面积进行测程实验,操作简单方便,结果可靠。利用本文研究成果可以算出任意棱镜组合所对应的测程,这样可更合理地使用棱镜,以便减少仪器幅相误差的影响,提高测程精度。Distance measuring is one of entire station meter's important technical specifications.To start from distance measuring formula of phase distance meter,the principle and method are discussed in this paper.This method can carry on the distance measuring examination in the short base or the short distance.At the same time,it has provided the possibility for the medium and long distance entire station meter distance measuring examination.By changing the effective surface area of reflector,the experiment can be done with this method.The operation is convenient and the result is reliable.It is possible to figure out the distance measuring of any prism combination by this method.It will be more reasonable to use the prism,so as to reduce the influence of the instrument error and to improve the distance measuring precision.
