1·Based on homogeneous barycentric coordinates, a new geometric variable, sharpness factor, is defined for measuring sharpness of independent vertexes.
基于齐次重心坐标，定义了新的网格顶点几何变量——锐度因子。
2·The differentiation matrices of unknown function are constructed by using barycentric rational interpolation.
采用重心有理插值近似未知函数，得到未知函数的各阶微分矩阵。
3·At first the original data points are resampled using barycentric coordinates, followed by fitting the resampled data points.
该方法首先用重心坐标对原始的数据点进行重采样，然后对重采样得到的数据点进行拟合。
