- 利用插值基函数很容易得到拉格朗日插值多项式，公式结构紧凑，在理论分析中甚为方便，但当插值节点增减时全部插值基函数lk(x)(k=0,1,…,n)均要随之变化，整个公式也将发生变化， 这在实际计算中是很不方便的，为了克服这一缺点，提出了牛顿插值。 -The use of interpolation basis function can easily obtain the Lagrange interpolation polynomial, the formula is compact and

- 考虑在一个固定区间上用插值逼近一个函数。显然，Lagrange插值中使用的节点越多，插值多项式的次数就越高。我们自然关心插值多项式增加时，Ln(x)是否也更加靠近被逼近的函数。龙格(Runge)给出的一个例子是极著名并富有启发性-Consider a fixed-interval interpolation using a function approximation. Obviously, Lagrange interpolation nodes are used the more the n
