However, during the practice of carrying the new rural cooperative medical service system, first we must solve these issues, such as: the ambiguousness of the attribute, the fuzziness of target location, the high cost and much difficulty of propaganda, the weak sense of peasants' heath care and shared risk, the weak administrative capacity of medical institutions, the worrying of doctor-patient moral standards, the lag of legislation, the low service level of designated medical institutions, the lack of operability in fund raises system and the weak responsibility consciousness of the government.

尽管我们在理论上能够阐明实施新型农村合作医疗制度的意义、试点的目标和要求、资金筹集和监管机制、医疗管理能力建设要求、完善农村卫生服务体系目标，但是在实施新型农村合作医疗制度的实践中，我们却必须要首先解决诸如属性不明确、目标定位模糊、宣传推动成本高、难度大、农民健康保健及风险共担意识淡薄、医疗机构行政管理能力较弱、对医患双方道德水准的担忧、立法工作滞后、定点医疗机构服务水平较低、筹资机制缺乏可操作性、政府责任意识不强等因素的制约。

尽管有限Clifford幺半群的量子偶确实是有限群量子偶的一个推广，但是[L2]中的量子偶一般情况下是不能够看作是Hopf代数量子偶的一个推广，这是因为我们在[L2]中要求所有讨论的弱Hopf代数都是交换的。

In the last chapter, on the basis of theories in paper [4, 5], the notions of strong mixing, weak mixing, generator and expansion of the variable-parametric dynamical system are introduced, it turns out that in variable-parametric dynamical system strong mixing implies weak mixing and then implies transitivity; it is proved that if and both are variable-parametric dynamical system, F conjugates with G , the members of F are communicate with each other and the members of G are also communicate with each other, what's more, they are both homeomorphism, then F is strong mixing implies G has the same properties; futhermore, we prove that F is strong mixing implies F Devaney chaos in the sense of modification in variable-parametric dynamical system and that F Devaney chaos in the sense of modification if and only if G Devaney chaos in the sense of modification when semi-conjugate with and they both are communicate and homeomorphism; at last, we illustrate that F has generator if and only if it has weak generator, and we also prove that if F is expansion, then F has generator.

在第三章中，我们在文[4，5]的基础上，提出了变参数动力系统拓扑强混合、拓扑弱混合以及变参数动力系统的生成子、扩张的概念；证明了变参数动力系统拓扑强混合蕴含拓扑弱混合，进而蕴含拓扑传递；证明了：如果，为两个变参数动力系统，F与G拓扑半共轭，且F两两可交换，G两两可交换，它们均为同胚映射，那么F拓扑强混合，则G也有同样的性质；本章还证明了变参数动力系统拓扑强混合蕴含F在修改的意义下Devaney混沌；在此基础上得出了：如果变参数动力系统与变参数动力系统拓扑半共轭，它们都两两可交换，并且它们均为同胚映射，那么F在修改的意义下Devaney混沌当且仅当G在修改的意义下Devaney混沌；得出了F有生成子当且仅当F有弱生成子；如果F是扩张的，则F有生成子。

And he is good who does not outrage, who harms nobody, who does not attack, who does not requite, who leaves revenge to God, who keeps himself hidden as we do, who avoids evil and desires little from life, like us, the patient, humble, and just"—this, listened to calmly and without previous bias, really amounts to no more than:'we weak ones are, after all, weak; it would be good if we did nothing for which we are not strong enough "; but this dry matter of fact, this prudence of the lowest order which even insects possess (posing as dead, when in great danger, so as not to do "too much"), has, thanks to the counterfeit and self-deception of impotence, clad itself in the ostentatious garb of the virtue of quiet, calm resignation, just as if the weakness of the weak—that is to say, their essence, their effects, their sole ineluctable, irremovable reality—were a voluntary achievement, willed, chosen, a deed, a meritorious act.

所有不去侵占、不伤害任何人，不进攻，不求报的人，所有把报复权上交给上帝的人，所有像我们这样隐蔽自己、避开一切罪恶，甚至很少有求于生活的人，像我们这样忍耐、谦恭、正义的人都是好人。"如果冷静而不带偏见地倾听，这段话的真实含义其实不过是："我们这些弱者的确弱；但是只要我们不去做我们不能胜任的事，这就是好。"但是这种就连昆虫都具有的最低等的智力（昂虫在危险时刻也会佯死，以免行动"过多），这个冷酷的现实却由于无能的伪造和自欺而被包裹在退缩、平静、等待的道德外衣中，就好像弱者的弱原是他的本质，他的作为，他的全部的、唯一的、必然的、不可替代的真实存在，是一种自发的举动，是某种自愿的选择，是一种行动，一种功绩。
