piecewise polynomial interpolation

Based on the newly-developed element energy projection ( EEP) method for computation of super-convergent results in one-dimensional finite element method ( FEM), the task of self-adaptive FEM analysis was converted into the task of adaptive piecewise polynomial interpolation.

基于新近提出的一维有限元后处理超收敛算法&单元能量投影（EEP）法，将有限元自适应求解问题转化为对超收敛解答的自适应分段多项式插值问题；
