The common weight functions are: Gaussian, exponential, spline, and compactly supported radial basis function (CSRBF) and so on.

目前常见的权函数有：高斯型、指数型、样条型以及径向基函数等。

The use of compactly supported elements generates a sparse solution space, reducing the computational complexity and making the technique practical for large models.

使用紧支撑的元素生成一个稀疏的解空间，减少了计算的复杂性和实际的技术，用于大型模型。

Lastly, using the compactly supported radial functional to take the place of the polynomial function, local radial point interpolation method, is presented in this paper.

最后，本文采用紧支距离基函数取代多项式基函数，提出了局部径向点插值方法，这是一种真正意义上的无网格方法。
