等价递归 meaning in Chinese

equivalent recursion

The thesis , in the probability analysis and computation , considers the failure history of space frames and trusses , adopts the bound criterion and algorithms on the base of system ' s critical strength , and introduces the soft self - adaptation control bound into the identification of dominant failure modes ; at the same time , with the incremental load method and differential equalized recursive method , computes the limit - state function of failure mode and probability index precisely under no leaking the dominant failure modes
文中在可靠性分析和计算部分，考虑空间刚桁架结构系统的失效演化历程，采用基于系统临界强度的约界准则和约界算法，将柔性自适应控制边界引入失效模式识别过程；同时，用荷载增量法和微分等价递归算法相结合，确保在严格不遗漏主要失效模式的情况下，快速准确地求解失效模式的极限状态方程和可靠度指标。
