The traditional commercial law is only the distinctive production under the feudal separation lasting for a long time in the Europe in the history, where the centralized countries lack of unity, and the political powers and rights distributed among other forces of King, feudatory and church. Its closure and particularity gradually disappeared after being brought into the national jurisprudence. But the scholar s vision had not yet been extended besides the civil law and commercial law, which is the historical origin and main cause of the afterwards problems of the civil and commercial unity and separation argument was difficult to draw a conclusion.

传统商法仅仅是历史上欧洲这一特定地区在缺乏统一的中央集权国家，政治经济权力分散于国王、封建领主、教会几大势力，封建割据长期存在这一特定环境下的独特产物，其封闭性和特殊性在纳入国家法的体系后逐渐丧失；但是学者的视野又没能拓展到民法、商法之外，这是后来民商合一与分立之争长期难成定论的历史根源与主要原因。

It can be concluded that to meet with the ideal separation effect in a relative short period, the following optional selection of experimental conditions should be carried on strictly: centrifuge rotor and gradient medium, which will influence separation capability; gradient density range, shape and slope, which is very important in separation degree; the methods of reorienting rotor,low and high rotor speed exchange and Gmax could be used in order to shorten separating time.

Similarly, if the strong shear, which could suppress all the scattering in the quiescent two phase region, stopped, the follow-up phase separation also displayed characteristics of anisotropism and relaxation, In this dissertation, the transposed"butterfly'and"streakpattern were observed for the first time within the shear-history-influenced phase separation, which is found closely relevant to the anisotropical relaxation behavior of macromolecules. 5. The phase separation kinetics of PS/PVME under oscillatory shear was further studied on the base of that done under simple shear. It is found that, under specific temperature and strain amplitude, the occurrence of phase separation is strongly contingent on oscillatory frequency and only intermediate frequency could effectively induce phase separation; If all considered oscillatory shear could stimulate phase separation, a fixed frequency can maintain specific most probable phase size and higher frequency yields smaller phase, which makes a higher elasticity but weaker stress relaxation; Furthermore, higher frequency can produces stronger compulsory oscillation on the MPPS but won't change the mean of the MPPS. Under given frequency and strain amplitude, the phase separation kinetics dramatically depends on the phase angle of oscillation and the phase separation corresponding to different phase angle follows different dynamical process.

在简单剪切场下相分离动力学研究的基础上进一步对振动剪切场下PS／PVME的相分离动力力学进行了尝试性的研究，发现：在一定温度和振幅条件下，相分离的发生强烈的依赖于振动频率，只有中等频率的振动剪切才能有效地促进相分离的发生；在都能使相分离发生的前提下，一定频率的剪切能够使体系维持一定的最可几相尺寸，较高频率的剪切导致体系形成的相区尺寸较小，因而体系的弹性效应较强而应力松弛效应较弱；同时，更高频率的剪切对最可几相尺寸的强迫振动效应越强，但不会使最可几相尺寸的平均值发生改变；在一定的振幅和频率条件下，相分离的动力学过程会强烈地依赖于相位角，不同相位角对应的相分离遵循不同的动力学过程但机理一样。
