摘要
本文给出了求双调和方程和脱里谷米方程的部分特解的一些公式;并得到了分布载荷的集度按纵向坐标的四次幂规律变化时,狭长矩形梁弯曲问题的有限项数形式的多项式精确解.
In this paper, some formulas for seeking a part of the particular solutions of the heavy harmonics and Tricomi equations are proposed a'nd we obtain the precise polynomial solutions of the number of finite items for the rectangular strip bending problem when the intensity of the distributed load varies with the fourth power of longitudinal coordinate.
