The finite element represen-tation of triangular prism and the treatment of boundary conditions ave described.

文中叙述了三棱柱体的单元表达式和边界条件的处理：手法。

Inappropriate formulation, Which the main mark of the precision of triangular prism is the verticality error, is corrected by discussion. Transformation of fundamental mode Gaussian beam passing through triangular prism is analyzed quantitatively.

通过讨论，指出了三棱镜精度的主要标志是垂直度误差的提法不妥。本文对基模高斯光束经三棱镜的变换进行了定量分析，表明基模圆高斯光束经三角棱镜变换后成为椭圆高斯光束。

It is proposed that the main mark of quality of the triangular prism closed related to experiment is the evenness of the refractive index n and the plane'ness of two transparent planes.
