点基形四面体的确定参数及作图

Determination of the Parameters of Tetrahedron

Ｅ．Ａ．格拉祖诺夫和Ｈ．Φ切特维鲁新著的《轴测投影学》中提及“根据波克－许华尔兹定理，要想按点基形四面体原形的投影来重新定出其原形，只要已知其形状，形状可由五个参数的条件来决定．”［１］本文对确定参数和作图，作进一步的研究和探讨。

The study of tetrahedron is of great significance in the segment of multiconnected-point framing and curved Surface. In the great work'Axonometric Projection'written by E. A Glazunove and H. Chetwrusin,the authors stated that the shape of tetrahedron can be determined by five parameters, but did not eva Iua te them. This paper makes a further study on them.
