In this paper, we discuss six theorems of the stability on minimal focal surface.

本文给出了伪球率线汇极小焦面稳定性的六个定理。

For a given reflector surface it is also important to locate the focal point of the best -fit paraboloid relative to the existing feed support structure.

对一个已给定的反射面，与馈源支撑结构有关的最佳吻合抛物面焦点的定位也是很重要的。
