中文说明：
反距离权重法主要依赖于反距离的幂值，幂参数可基于距输出点的距离来控制已知点对内插值的影响。
English Description：
The inverse distance weighting method mainly depends on the power value of the inverse distance, and the power parameter can control the influence of the known point on the interpolation based on the distance from the output point.
