The molecular weight dependence of the distribfition of polymer molecules between the coacervate and the dilute phases on the phase separation of polymethylmethacrylate-acetone-methanol system has been proved to follow the relation first derived by Flory for binary systems: f"_j/f′_j = Qe~_j where f"_j and f′_j are the weight fractions of the polymer molecules of molecular weight M_j in the coacervate and in the dilute phases respectively, while Q and σ are parameters.

1。聚甲基丙烯酸甲酯-丙酮-甲醇体系的两次分相实验用θ-溶剂中的沉降速度法测定分相前试样和浓相的分子量分布曲线，得到高分子在浓稀相重量分配的分子量依赖关系 f_j=Qe~证实Flory的溶度函数形式与实际相符，并适用于三元体系的相分离，但Q值与两相体积比R值并不相同。 2。再分级使级分的分子量分布宽度随再分级次数的增加而减小，通常认为到第三次再分级其效果已不显著并不确实。

In chapter 4, by AREELS, the Generalized Oscillator Strength Density Spectra were measured in the energy region from 56 to 66eV, with the incident energy 2. 5 keV and energy resolution 80 meV, at scattering angles from 0°to 6°, corresponding to the momentum transfer K〓=0.03~2. 01 a. u. The Fano profile parameters f〓 and q for the optically allowed transition 〓(0, 1)〓P°and the optically forbidden transitions 〓(1, 0)〓S〓and 〓(1, 0)〓D〓 were obtained as a function of K〓. With the hyperspherical coordinate wavefunctions, the dynamical correlation are discussed qualitatively. So, a new experimental way to study dynamical electron correlation effect is opened.In chapter 5, the widely used R-matrix theory was introduced. Then, the GOSDS for the optically allowed excitation series (1s〓)〓S〓→〓(0, 1)〓P°(n=2-4) were calculated by this method, and the Fano profile parameters f〓 and q were obtained sequently. So the electron correlation effect can be described by these parameters quantitatively, and the theoretical results were compared with our AREELS experimental results.
