摘　　要：利用杆件微弯的曲率公式和面积向量法,求得一端固定、一端自由压杆的临界压力欧拉公式,为该约束条件下细长压杆的临界压力公式推导提供了另一种方法.The curvature formula of tiny curved rod, together with the vector method of area, is applied to inference for Euler formula about critical load of slender compressive rod which one end is fixed and another is free. This inference method presents another approach to Euler formula about critical load of slender compressive rod with the given support.

关 键 词：细长压杆 临界压力 面积向量法
