摘　　要：本文介绍了一种反距离权重插值法的理论推导以及求解的方式。这种方法的基本原理是利用有限数据点的已知信息对待求点的未知信息进行插值，并通过得到插值点的值计算新的插值点的值。由此，解决了由于温度点数量有限无法对温度场进行全面描述的问题并将该方法应用在二维温度场未知温度点的求解过程中。该方法具有简单、实用、计算量较小的特点。The paper introduces a kind of inverse distance weighted interpolation theoretical derivation and its solving way.The basic principle of this method is that to use known information limited data were interpolated to the unknown information for point,through the obtained interpolation point value to calculate the new interpolation point value.Thus,it is solved that the problem that limited number of temperature points can not be comprehensive description of temperature field,and the method is applied in the process of solving the unknown temperature points in the two dimensional temperature field.The characteristics of this method are simple,practical,less amount of calculation.
