摘　　要：构造矩形网格节点上的插值函数是工程设计中经常遇到的问题,插值函数的性质对工程设计质量有着重大影响.本文通过建立一系列基函数,构造出了两个在具有(n+1)2个节点的矩形网格的插值函数,这两个插值函数不仅是初等函数,且具有良好的光滑性,简单易用.Interpolating functions on the nodes of rectangle net is the topic during the engineering designing. Its characteristic has very important effect on the engineering project. Through establishing a series of primary function, two interpolating functions on the nodes of rectangle net have been established. The two functions are elementary functions and they are smooth, oversimplified and easy to use.
