| 摘 要： | 对给出的一组数据（xi,yi）（i=0,1…n），根据不同的原则我们可以利用插值法和曲线拟合法分别来构造近似函数表达式。通过例子来对比这两种方法的优缺点，虽然它们都有缺点，但都是实用性很强的方法，所以还是要多加重视。

| Abstract: | To give a set of data, according to different principles we can use interpolation and curve fitting, respectively, to construct the approximate function expression. Through the examples we compare the advantages and disadvantages of these two methods.They have disadvantages, but they are very practical ways, we still have to pay more attention to them. |
