摘要
空间几何中,前人已得出三球有内公切面的结论,但并未给出它的方程.探讨了求得三球内公切面方程的方法.
In space geometry, our forefather has pointed out the existence of internal common tangent planes of three spheres. But, how do we find the internal common tangent planes？ In this paper, we give the method finding common tangent planes of given three spheres.
