| 摘 要： | 本文分析了闭口薄壁杆件的扭转翘曲和畸变翘曲之间的关系，给出用一个或两个函
数来表达这两种翘曲的判别条件。文中还着重讨论了扭转和畸变翘曲函数分别与扭
转角和崎变角之间的关系，指出不能用后两者的一阶导函数来代替前两者.为正确选
用翘曲函数提供了理论依据。

| Abstract: | This paper analyses the relationship between torsionaf and distortional warping of thin walled bars with closed cross section. The condition of defining the warping displacements with a single function or with two functions is advanced. The relationships between torsional angle, distortional angle and warping functions are discussed, providing the theoretical basis for the determination of warping functions. |
