Since the reform and opening to the outside world in China, with the constant adjustment of ownership structure and production relation, China has experienced great changes of stratum structure and stratified differentiation, which brings complex impact on political participation mechanism, simultaneous, political participation affects the process of social stratum changes in a degree.

改革开放以来，随着所有制结构和生产关系的不断调整，我国社会阶层分化日益明显，阶层结构发生了重大的变迁。阶层结构的变化给我国的政治参与机制带来了十分复杂的影响，同时公民政治参与也在一定程度上影响阶层结构变迁的进程。

In order to evaluate the image scrambling degree effectively,the paper gives difinition of the continuity extent.And a new evaluation method of image scrambling degree based on the number of the continuity extent changes when the positon of the pixel changes is provided.The simulation result shows that the method can measure the impact of the every image scrambling phase.

Faraday's law is that when the flux in the conductor loop changes, it produces electromotive force in the conductor loop, and obeys to contour integral law , Maxwell Curl Theory is that when the magnetic intensity of a certain point in ether space changes, there produces electric field at that point in ether space, which is the field mutual production theory of "electric field produces magnetic field and magnetic field produces electric field" in the free space which everybody is familiar with, and it obeys differential law , Lorentz magnetic force is that when metal electrons cut magnetic lines, metal electrons forced by move along the conductor to form inductive current, in fact, it doesn't matter whether coil moves or magnet moves, only if there exists relative motion between magnetic field and conductor, metal electrons must cut magnetic lines, which is,"coil stills while magnet moves to the left" and "magnet stills while coil moves to the right" these two situations are the same, which both belong to metal electrons having cut magnetic lines.

法拉第定律指导体环路里的磁通量发生变化时，在导体环路上产生电动势，而且服从围线积分律；麦克斯韦旋度理论指以太空间某点的磁场强度发生变化时，在以太空间的该点产生电场，即大家熟知的自由空间里"电场生磁场与磁场生电场"之互生场理论，而且服从微分律；洛伦兹磁力指金属电子切割磁力线时，金属电子受力沿着导体漂移而形成感应电流，其实，无论线圈运动或是磁铁运动，只要磁场与导体存在相对运动，则金属电子必然切割磁力线，即，"线圈静止而磁铁向左运动"与"磁铁静止而线圈向右运动"这两种情况是一样的，都属于金属电子切割了磁力线。
