All in all, My dissertation mainly focuses on phenomena existing in Chinese venture capital investment market with double principle-agent theory. According to actual conditions, we think that shareholders who are full of wishes to supervise the daily management of the venture capital should be nurtured. Another, the evaluation system with government as cautioner, the incentive and restrictive mechanism implemented and anonymous assess as trait in the beginning of process should be improved uninterrupted. Last but not least, in the choosing of exit ways of the venture capital, the MBO method is one that couldn't be ignored.

并在探究两层委托代理互动关系的基础上，针对我国风险投资市场委托代理中的主体缺位、政策滞后等问题，提出要明确风险投资领域宏观与微观环境建设的政府责任与企业责任：在风险资本市场，要大力宣传和鼓励以民营资本为代表的积极股东的参与；在风险投资项目评估中，应当不断完善以政府担保为主体的、贯彻激励约束机制的、以专家匿名评审为特点的项目评估体系；在风险资本退出模式中，我们强调要更加重视MBO方式对风险投资事业的积极作用。

That life comes with death is a fate common to all human beings One could observe the phenomenon of death but never understand its reality which explains why humans have had such a great fear of death Yet death remains a brutal fact after all and only with an adequate interpretation of it can human being face up to death The present dissertation is intended to explore ancient views on death in terms of three kinds of "life-seeking" attitudes: metaplasia resurrection and longetivity The primitives employed the collective myth-making to explain the riddle of death and create the belief in the "solidarity of life " Chuang-tzu accepted such a belief and developed in addition the idea of "qi" through his concept of "metamorphosis " In the period of Eastern Zhou it became popular to imagine dead people turning into ghosts and this brought out the idea of "soul " Yet is there another world after one dies?

有生必有死，是人类共同的命运。死亡的现象可以观察，但死亡的真相却是永远无解，因此人类害怕死亡。可是，死亡毕竟是一项事实，对它有所诠释，才能让人明白如何面对死亡。这篇论文希望探讨古人的死亡观，是以三种「求生」的态度：化生、复生，与长生，来进行讨论。原始人类集体创作神话来解释死亡谜团，透过「变形」此一律则，产生「生命一体化」的信念。庄子继承「生命一体化」的信念，他从「变形」的观念发展出「气」的观念，藉此说明他对於死亡的态度。东周时期，人死之后变成鬼的想法普遍流行，产生「魂魄」的说法。人死后是否会有另一个世界？

This dissertation is just a carrier of education and culture but not a tool of propaganda. Neither is it a certain hypocritical preachment with which education is emblished. On the contrary, it takes its stand upon the true internal world of URPWPSs. Although it is true that pen, paper, and taperecorder are merely technological implements, the user of them will be able to throw his concern to man, if only he has all the qualifications for humanistic spirit.

本文采用质的研究方法，直接走进工农兵学员的"生活世界"和"意义世界"中，以工农兵学员的"自身话语"为分析对象，而不是以"泛政治化"话语或作为某种政治符号的话语为分析对象，这一话语的转变本身就是对教育领域大叙事的政治乌托邦的一种解构，我认为这体现了一种人文精神的立场态度，即民间立场和世俗关怀。

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。

Simulations are given for all control schemes designed in this dissertation, and they show that the control schenies can not only ensure the global boundness of all closed-loop signals, but also have good control effects (that is, the steady output tracking error is very small).

This dissertation was focused on the research about the formation and evolution of NQB from the Late Triassic to the early middle Epoch of Jurassic Period, including integrated analyzing the characteristic of the key stratigraphic surfaces, the time of the key stratigraphy, regional rock straigraphy, biostratigraphy and chronostratigraphy, sedimentary system and depositional facies. On basis of these analysis, a tectonic evolution model have been established for NQB during from the Late Triassic to the early middle Epoch of Jurassic Period.1. After the systematic surface analysis about main stratigraphy units, we found that:(1) the bottom of Xiaochaka formation was comformity with the middle Triassic in the basin, and in the north margin it was deposited and overlapped on the different period stratigraphy before Triassic.(2) The top surface of Xiaochaka formation developed regionally karst and paleo-karst breccia, and was uncomformity with Nadigangri Formation, these things suggest that NQB in Xiaochaka depositing stage was developed from middle Triassic basin, and then an extensive regression occurred, the deposition was over and erosion come into being.(3) The lithologic assemblage, geochemistry, mixed fossils, and stratigraphy overlapping characteristic of Quemocuo Formation in early middle Jurassic indicted that the uncomformity surface was an extension-unconformity.2. Integrated analysis about stratigraphy division and correlation indicted that:(1) the paleontologic assemblage of Xiaochaka formation show its time was Carian -Norian stage of late Triassic. According to it was overlapped by late Triassic Nadigangri Formation, so Xiaochaka formation should be Carian - early Norian stage.(2) the SHRIMP Zircon U-Pb age of Nadigangri formation volcanic rocks wear vary form 216 to 205 Ma, so its time should be Norian, but maybe extended into Rhaetian Stage.(3) The age of its bottom volcanic rocks, the fossil assemblages of its middle and upper members and overlapped by lower Jurassic, indicted the age of Riganpeicuo Formation was Norian - Rhaetian stage. And the same time, the volcanic rocks geochemistry of Nadigangri and Riganpeicuo formation both reflected that they wear formed in rift tectonic settings. The lower lithologic and surface characteristic, fossil assemblages and its upper maybe was conformity with lower Jurassic, all reflected that the age of Tumengela Formation in Tumen area should be Norian - Rhaetian stage.

The main concern of this dissertation is the relations between republicanism and modern political society. It demonstrates that republican commitment is the legitimacy of modern politics, which means that all members of a civic community share the political sovereignty and civic community should put more emphasize collective self-rule, but both dynamics of modern society and cotemporary dominating political social and moral language of liberalism go against the republicanism's commitment, so this dissertation explores that the civic community should renew the common good, regenerate the deliberative public sphere and foster civic virtue so as to remedy the maladies of modern society.

本文的核心问题是共和主义与现代政治的相关性，主要论点是现代政治的正当性基础在于共和政治的公民共同体全体成员共同享有政治主权，也即公民共同体集体自治原则，但是现代政治一方面是建立在对共和政治的规范性承诺基础之上，另一方面现代社会的内在动力以及现代社会的主流政治社会道德话语对于共和政治的实现和维持或者存在威胁，或者隐含缺陷，要维持和实现共和政治的规范性承诺，需要恢复公共善的优先性、重建协商的公共领域以及塑造公民德性。
