If this thesis is correct, then one can quite clearly see why the bourgeois class struggle dominates the proletarian class struggle from the outset and why the proletarian class struggle has needed so long to take shape and to find its own forms of existence, why the class struggle is fundamentally unequal, why it is not conducted using the same practices on the part of the bourgeoisie and the proletariat and why the bourgeoise has engendered forms in the ideological state apparatuses, whose task it is to preempt the revolutionary action of the working class and to subordinate this class.

如果这个论题是正确的，那么人们可以非常清晰地看到为什么资产阶级的阶级斗争从一开始就支配着无产阶级的阶级斗争，无产阶级的阶级斗争为什么需要那么长的时间才能成形并找到自身的存在方式，为什么阶级斗争从根本上是不平衡的，为什么对于资产阶级和无产阶级来说，不能运用相同的实践去进行阶级斗争，为什么资产阶级（原文是bourgeoise，意为资产阶级妇女，疑为bourgeoisie之误）也在意识形态国家机器当中构造了诸种斗争形式，后者的任务就是预先取代工人阶级的革命行动并让这一阶级服从于它。

Through the analysis on the connotation of social class consciousness, the thesis illustrates that social class consciousness is different from individual consciousness and economic consciousness, but it is a particular social class systematic understanding of its historical status and historical mission under certain social relation of production. On the basis of that, the thesis historically analyzes the bourgeoisie"s class consciousness, affirms that the bourgeoisie"s class consciousness is a historical progress comparing with the pre-capitalistic society, and reveals from a whole view the falsity and inauthenticity of the bourgeoisies class consciousness as well.

Wrights class theory has great significance in practice to our understanding of the new changes in class relations of contemporary capitalism and the development of Marxism according to the new changes: Firstly, Wright'theory of the new changes in contemporary capitalist class relations will enable our understanding of this class structure to be founded on more complete analytical data, and make us have a more accurate knowledge and understanding about the non-applicability of Marx's prediction in his class theory of polarized class relations in capitalism.

赖特的阶级理论对于我们认识关于当代资本主义社会阶级关系新变化并且根据这种新变化来发展马克思主义具有很大的现实意义：首先，赖特的当代资本主义社会阶级关系新变化的理论，使我们对当代资本主义的阶级结构的认识能够建立在比较完整的数据分析基础之上，也使我们对马克思所预言的资本主义阶级关系两极分化的阶级理论在当代的不适用性有了更加准确的认识和了解。

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。
