As we know,Newton's interpolation polynomial is based on divided differences which can be calculated recursively by the divided-difference scheme while Thiele's interpolating continued fractions are grared towards determining a rational function which can also be calculated recursively by so-called inverse differences.

大家都知道，牛顿的插值多项式是基于均差的，可以递归出均差，而Thiele插值连分式是一个有理插值，也可以递归地计算，即所谓的逆。

The CPP was separated into five fractions using fractional precipitations by solvent/nonsolvent technique. Densities for binary mixtures of five fractionated and unfractionated CPP which contains a mass fraction of 30 % chlorine with solvents were determined. At a fixed temperature, concentration and solvent, the densities for binary mixtures of fractionated and unfractionated CPP with solvents have the same value.

用沉淀分级方法对氯含量为30％的氯化聚丙烯进行分级，得到5种窄分子量的级分，测定了氯化聚丙烯的不同级分与不同溶剂组成的二元混合物溶液的密度，在溶剂一定、浓度一定、温度一定时，不同级分氯化聚丙烯溶液的密度是相同的，不受分子量及其分布的影响。
