递归方程 meaning in English
recursion equation
Examples
- Application of recursion tree in solving the asymptotic order of recursion equation by using iteration operation
递归树在用迭代法解递归方程渐近阶中的应用 - Equation ( 2 ) can be explained as follows : a problem of x - scaled can be transformed to a same problem of ap - s x / a scaled with a calculating overhead of xq f ( z ) , so t ( x ) , the cost ( complexity ) of this problem , satisfies the above recursive eqution
方程( 2 )可以做如下解释:一个规模为x的问题，可以以x “厂( : )的计算代价化为。尸个规模为三的同一问题，那么该问题的计算成本(计算复杂性) t ( x ) a就满足上述递归方程。 - Considering the fuzziness of some boundary conditions enviroment media , and especially some loads in the engineering structure analysis , we go further into the computation based on the dynamic problem of fuzzy finite element ( ffe ) , study further and systematically the analysis and solution . the principle of fuzzy minimum potential energy is established , and the balance equation of fuzzy finite element is reasoned by making fuzzy variation . at the same time , the dynamic balance equation of stochastic by making stochastic variation ， also the fuzzy stochastic dynamic balance equation is deduced . based the theory that the degree of the fuzziness and probability can be measured , in the other word , by using the concept of fuzzy entropy and entropy , pure fuzzy dynamic structure is given through transforming the probability to fuzziness . for the fuzzy parameter can be regarded as a fuzzy vector with dimensions , the structure ' s eigenvalue , by the theory of small parameter
建立了模糊瞬时最小势能原理，运用模糊变分原理导出了模糊有限元动力平衡方程；同时，利用随机变分原理导出了动力问题的随机有限元方程，同时得到了模糊随机动力问题的有限元平衡方程。根据模糊度和概率度可以度量的原理，即利用模糊熵和概率熵的概念，把结构的随机性等效地转化为结构的模糊性，得到纯粹模糊性的动力结构。把结构所具有的模糊参数看作一个维的模糊向量，利用小参数摄动原理，把结构的特征值，特征向量和位移都在模糊向量的均值处进行泰勒展开，得到一组递归方程，即可以求得结构的模糊特征值，特征向量和模糊位移。
