The final result indicates that in the expression of the completeness relation,the integral path is along the real axis from -∞ to ∞ but runs over near the origin,which is contrary to the Cauchy principal value appearing in previous works.

同时得到展开式中的积分是沿实轴从-∞到∞，但在原点附近将从上方绕过。这不同于过去所得的C auchy主值积分。为最明确显示这一差别，在单孤子情况下又用平方Jost函数的显式，直接作了验证。

The social level structure is defined from its basic conception, in-depth meaning and characteristics. The term refers to a functional being and social reality, a unity of physical space and value space as well as connectional and theoretical existence. Viewed from the perspective of political philosophy, the social level structure is a political sovereignty grading or ladder in a state who values the supremacy of sovereignty, penetrating into economic, cultural and social fields, universally forming social relationship. Based on general social structure, social system and political sovereignty, the social level structure is an abstractly summary of social hierarchy which is neither a copy of political structure nor simply addition of economic, cultural and social structure. The social level structure is long hidden but universally existing, deeply affecting and shaping social system, people's life and thinking. Based on the above, the thesis probes the social foundation, evolutional law, fundamental quality, running mechanism, historical function, current significant and the reform necessity.

从社会层级结构概念的基本规定、深层意蕴和性状表现三个方面界定社会层级结构概念，认为社会层级结构既是一种实体性存在和社会现实，也是一种观念性存在和理论构造，是物理空间和意义空间的统一；从政治哲学视野，社会层级结构是在政治国家内部按照权力至上的方式形成的权力级别或权力阶梯，并渗透到经济、文化、社会领域，形成具有普遍性的社会关系体系；它以总体社会结构为依托，以社会制度为外化，以政治权力为中轴；它既不是政治结构的翻版，不是社会阶层结构的别名，也不是经济、文化、社会结构的简单叠加，而是对它们层级性的一种抽象和概括；这种结构长期隐而不显，但却无处不在、无时不有，深深地影响和牢牢地控制着社会制度、人的生活和人的思维方式。

Moreover, we established the model of apoptosis induced by corticosterone and explored the effect of gangliosides, which is a active component in pilous antler, on this apoptotic cell model.

The calculation results shows that ,(1) when the rotor rotates at the working speed, a local regurgitant whirlpool that is rightabout to the rotor"s rotating direction appears in the classifying region, which makes the separated granules come back to the outside of the classification district and influences the classification efficiency of the turbine classifier;(2) in the condition of a low rotating speed of turbo rotor, ultrafine particles can follow the gas phase by and large, but when the rotating speed increases, a phenomenon of velocity slippage between two phases appears evidently;(3) A operating parameter, air flow rate is so important that can directly influence the stability of flow field in classifying chamber, the bigger the air flowrate is , the steadier the flow field is;(4) Compared with straight blades, the new shape of blades with backward crooked elbow are helpful to improve the stability of flow field and form whole stream easily, also beneficial to advance the classification accuracy and classification efficiency;(5) The motion trace of particles are very complicated when the turbo rotor rotates at a high speed, the constant bounce of the particles appear between the blades and the coarse particles are even bounce back from the inlet, only the finer can pass through the classification area from the oulet;(6) Along with the increase of the rotor"s rotating speed, radiah axial and tangential velocity all begain to fluctuate repetitively like sine-wave, the smaller the particles are, the more violently they fluctuates.

数值模拟结果表明，(1)在涡轮达到工作转速时，在分级区域形成了一个与涡轮旋转方向相反的局部回流涡，它使得分离出来的细粒重又被带回分级轮外边缘，从而严重影响分级机的分级效率；(2)粉尘粒子在涡轮低速运动情况下，基本上能跟随气体运动，但随着转速加大，两相之间出现了明显的速度滑移现象；(3)分级机工作时的风量也是一个比较重要的操作参数，它可以直接影响到分级机内腔流场的稳定性，风量越大，流场越稳定；(4)同直叶片形状相比较，带后弯导板的叶片，有利于改善流场的稳定性，流场容易形成整体流，对提高分级效率和分级精度都非常有利；(5)粒子轨迹线在涡轮转速较高时十分复杂，有的出现了反复的弹跳现象，大颗粒不能通过分级区域而从进口返流了，只有细小的颗粒才从出口处流出；(6)涡轮转速加大时，粒子的径向、轴向和切向速率出现了明显的类似于正弦波的脉动现象，颗粒越小，脉动程度越为剧烈。
