摘　　要：介绍了一种检测小工件平行度和垂直度的新方法。利用反射棱镜将常规的问接测量变为直接测量，使测量不受外部环境的影响，方便、快速、准确，文章还对测量误差作了分折，并提出了消除误差的方法。A new method for measuring the parallelism and the verticality of a small size workpiece is introduced. Using the reflective Prism,two surfaces of tile workpiece being tested are directly compared to each other without any other referent surface. No strict environment condition is required for the operation, The result is accuracy and reliable' System errors of the instrument are analyzed,and measures to avoid errors are also discussed'
