差值求解的fortran，如牛顿插值，Hermite插值等，同时涉及三次样条插值的边界条件-The difference between solving fortran, such as Newton interpolation, Hermite interpolation, while the boundary conditions involving cubic spline interpolation

三次样条插值之固支条件，用于三角网格后处理边界差值，特便是应力云图-clamped cubic spline interpolation conditions for triangular mesh boundary difference,, is the stress nephogram
