分析了在适当的边界条件和约束下三次多结点样条插值的逼近阶；
The approximation order of the interpolation with the appropriate boundary conditions and constraints is analyzed.
第二，用单元的结点坐标、结点应力以及等参插值函数，插值计算这些点的总体坐标及应力。
Secondly, the global coordinates and stress values of the points are calculated by using standard isoparametric interpolations, the node coordinates and the known node stresses.
结点上的变量值采用时间序列回退内插的新的插值格式，而不是传统的空间内插方法。
The interpolations are made along the time-line with varying reach-back time distance, rather than the more widely used spatial interpolations.
