近似法

Radial basis function coupled with a polynomial basis function was used as a trail function, and a Heaviside function was used as a test function of the weighted residual method.

这种无网格方法采用径向基函数耦合多项式基函数来近似试函数，采用Heaviside函数作为加权残值法中的权函数。

With the development of highway construction, the speed of cars has been gradually increased.

随着公路的发展，汽车的车速也在不断提高。

So we basically had to develop a bond with the animal in terms of socializing with it.
