The first subject to the advertising industry on the environmental background of the current study based on reality, and from the spread of the evolution process of the media environment, audiences shape the evolution of the process of market and economic environment and national policy guidance as well as the social environment and the evolution of the process of public opinion, etc. discussed the ecological environment of the advertising industry on advertising exerts a subtle influence theory, is intended to combine the social environment through the development of the industry and actual cases to observe and verify Advertising thinking theory to make it too heavy at this more closer to its guiding the nature of the role of the characteristics of the formation and perfection of the development of China's national conditions in line with the theory, the consolidation of personnel training in the advertising industry advertising the basis of academic theory-building status, and further guidance on the practice of China's advertising industry.

本课题先就以广告业当下的环境背景等现实研究依据出发，从传播、媒介环境的演化进程，受众市场形态的演化进程、经济环境和国家政策的导向以及社会环境和舆论的演化进程等方面，探讨了广告业的生态环境对广告学学科理论潜移默化地影响，意在通过结合社会环境和实际业界发展的案例观察和思考中验证广告学学科理论，使其在此过重中更接近它指导作用的本质特征，形成和完善符合中国国情的发展理论，巩固广告业界人才培育中广告学学科理论建设的基础性地位，并进一步指导中国的广告产业实践。

This commentary raises and examines several implicit challenges that emerge from attempting to construct theory: defining the function of theory itself; what purposes it is being asked to serve; the underlying analytical basis for a theory; its intellectual coherence and the capability to connect disparate environmental, social, political and economic dimensions; and the problems associated with theory-building at the empirical level.

本评论提出并考察了一些在构建理论的努力过程中得以显现的隐性的问题：明确理论自身的功能；它所要达到的目的；一种理论最根本的分析基础；它在理性上的融贯一致性，把环境、社会、政治和经济等不同方面结合在一起的能力；以及在经验层面上与理论构建相关的问题。

Based on it, the authors try to propose the developing tendency of public finance theory research in the coming 21st century.

在此基础上，21世纪中国财政研究至少要表现出五个方面的发展趋势：研究的理论取向将是公共财政理论体系；研究方向将更趋向于数学化、实证化；财政理论的研究将既体现出宏观特征，又体现出微观特征；财政研究将既注重财政理论的研究，又注重财政政策与制度的研究；与其它学科研究的交叉与渗透将得到进一步的发展。

In the second part of the paper, the sport techniques of the flight elements was analysised in-depth theoretically by the movement technical structure:①the giant swing was first analysised in mechanics by applying the Kane's method, the dynamic equation of 5-link multi-body model was established, and the computer simulation software of the giant swing on the high bar was developed.

其次，作为单杠上飞行动作系统性研究的另一主要方面，本论文对飞行动作一般技术结构中的各技术环节进行了深入的理论分析：①着重对飞行动作准备阶段的回环运动技术进行了动力学分析，主要采用了多体力学理论中的Kane方法，建立了5环节人体回环运动的动力学方程，并应用计算机数值仿真技术研制开发了用于回环运动动力学分析的数值仿真软件，进而以动作实例对回环运动进行了数值仿真与误差分析，其所得到的数值仿真结果能够满足对人体回环运动的动力学分析和仿真要求；②对于飞行动作的撒手技术环节，本论文从人体环节相对运动角度，来分析撒手时人体质心的运动以及撒手时角动量参数，并列举了几种飞行动作撒手技术的基本力学指标；③关于飞行动作的空中技术，论文在总结了空翻转体动力学机理的研究成果基础上，对人体空中运动定量化问题进行了一般性描述，并进一步应用刚体动力学理论，着重建立起了描述空翻与转体技术之间定量化的关系，讨论了空翻转体运动的稳定性及其运动模式的转换问题，它对于定量地评定空翻转体技术以及今后对空翻转体动作进行数值仿真都具有理论上和实践上的重要意义；④关于飞行动作再握技术环节，本论文避免了以再握瞬时性的力学参数指标来描述再握技术特征的简单化途径，提出以再握下摆与回环下摆相对比的方法来研究再握技术，并以飞行动作再握技术的具体实例进行了对比分析，表明再握下摆技术相比回环下摆技术有着相当的困难性和复杂性，运动员对再握下摆过程中各环节的相对运动实施有效的控制，是连接高难动作以及顺利流畅地完成成套动作的关键。

In addition, the traditional Marxism neglects the poverty of non-producer such as those unable to work. Cohen points out that, due to the flaws above, the traditional Marxism cannot give an effective refutation to Nozick's justification of capitalism. Fourthly, according to Cohen, the traditional Marxism resorts to the principle of self-ownership held by Nozick when it tries to prove the necessity of equality and to vision the socialist principle of distributive justice as well as to criticize the injustice of capitalism. Thus the traditional Marxism holds the same premise with Nozick's theory of justice in holdings, so it's easy to be attacked by Nozick, let alone an effective refutation to Nozick.

第四，传统马克思主义本身在对平等必然性的证明、对社会主义分配正义原则的构想、对资本主义不正义的批判等方面，都没有拒绝诺齐克持有正义理论所坚持的自我所有原则，这就造成了传统马克思主义与诺齐克持有正义理论拥有同一个前提，所以就容易受到诺齐克持有正义理论的攻击，也就谈不上有效回击诺齐克持有正义理论为资本主义所作的辩解和对社会主义的否定了。
