摘　　要：正交各向异性夹层板的弹性弯曲方程为四阶偏微分非齐次方程组，很难得到函数式解答，只能寻求数值解法．本文利用差分法建立了差分方程，并通过具体算例比较，误差在允许范围内．The elastic bend equation of the double-layered slab with right-angles and difference in nature each direction is a four-step nonsingular distortion differential cou- pled equation. As it is difficult to find the solution of the function formula, the value so- lution method is searched for. In this paper, differential method is used to establish dif- ference equations by comparison of practical examples. The errors are in permitted lim- its.
