摘　　要：本文探讨了用计算机计算含未知量元素行列式的方法与途径，提出了“保值回跳”的思想。并提供了以该思想为基础而编制的空间桁架结构位移响应关于截面设计变量显式表达式程序计算的若干算例。This paper presents a new method named 'Keep Value And Return', to calculate the formulations of determinants whose elements are unknow variables by coin puters. Some examples, caclulating the displacement formulations of spetial truss structures whose stiffness matrix are linear founctions of the design variables, are given in this article.
