The stable field problem is discussed in rectangle area with method, which are eigenfunction and superpositionle. 文章结合叠加原理,应用本征函数法研究矩形区域上稳定场问题.
The sparse finite element is considered for solving eigenvalue problems. Based on an interpolation postprocessing, superconvergence estimates of both eigenfunction and eigenvalue are obtained. 应用稀有限元方法讨论特征值问题的求解,通过插值后处理,得到了特征值和特征函数的超收敛结果。
Based on the paper, this paper gived a new definition for an empirical mathematical expectation: proved an estimate empirical mathematical expectation and discussed the relation be-tween empirical mathematical expection and empirical 在文[]基础上,给出了经验数学期望的定义,证明了经验数学期望是数学期望的一致估计,并讨论了经验数学期望与经验特征函数的关系.
