摘　　要：提出了利用两平面反射镜多次反射来虚拟室外基线场,在室内完成检定光电测距仪及全站型电子速测仪测距部分的解决方案;在现有技术的层面上对该方案所面临的技术难题进行了探讨,对其可行性进行了论证;对该方案实施1000 m测长的不确定度进行了详细的分析和计算,得出了该方案完全可行的结论。A solution scheme that can inextenso verify electro-optical distance mster and the EDM system of electronic total stations inside a laboratory by establishing fictitious outdoor length standards with two plane mirrors in which the ray will be reflected repeatedly has been proposed in this paper. The difficulties that the scheme will have to solve, have been discussed and the feasibility has been demonstrated with existing technology and experience. Detailedly the extend uncertainty about measurement result of 1000 m by this method has been analysed and accurately calulated, and has got the conclusion that the scheme is feasible entirely.
