摘要
本文证明线弹性体表面小域中作用的平衡力系在弹性体中的影响随到小域的距离而单调衰减,但不一定趋于零,就是说,平衡力系可能在无穷远点造成非零的影响,所以圣文南原理的传统提法并不能一般性的成立.
It is proved here that the effect of an equilibrium system of forces acting in a small sphere of the surface of an elastic body monotonously decreases but does not always approach zero, or say, the classical expression of Saint-Venant's Principle is not commonly valid.
