These algorithms can get very high precise mapping together with high speed of convergence, because the mapping error is able to reach zero and the computational complexity is at order of polynomial.

新算法有很高的精度及较快的运算速度，这是由于映射误差可以为零，其计算复杂性是多项式阶。

Here, we chose simple polynomials as shape functions, and derive the element matrice on the regular element (a isosceles triangle with a right angle).

这里选取逐渐升幂的简单多项式作为基底函数，并且据此推导了升到六阶的正规单元矩阵。
