由于对称阀控制非对称缸两个运动方向上系统的开环增益及某些参数的不同，使得两个方向上的动态特性不对称，主要表现在超调量、调节时间、振荡次数和稳态误差等几个方面，这种本质上的非线性和非对称性给系统控制带来困难。

Ringel realized positive parts of semisimple Lie algebras in the framework of Ringel-Hall algebras. The main result of this thesis is to build a geometric and topological model over triangulated categories such as derived categories and stable module categories of repetitive algebras. We defines a Lie bracket by Euler characteristics of constructible subsets and thus realizes infinite dimensional Lie algebras of various types with non-degenerated bilinear form.

本文的主要结果是在导出范畴和重复代数的稳定模范畴等三角范畴水平上建立相应的几何-拓扑模型，并利用相应可构集的欧拉示性数定义了一个Hall代数的交换子乘法，从而在三角范畴水平上实现了一大类无限维李代数的整体构造，并且这类李代数本质上都具有非退化的不变双线性型。

Theoretical Part: Through theoretical analysis of chemothermodynamics, combustion and engineering thermodynamics, factors that affect explosion limit were determined, which include temperature, pressure, spark ignition energy, electrode shape, direction of flame propagation and size of explosion vessel.

理论部分：根据化学热力学、燃烧学和工程热力学的基础理论，从本质上定性地分析了爆炸极限的影响因素，包括温度、压力、爆炸容器的大小、点火能量大小、以及火焰传播方向等，得出了这些影响因素对爆炸极限的影响规律，以确保实验有完整的理论基础指导；在此基础上本文提出了一种新的推算在常温常压下可燃性纯质和混合工质制冷剂爆炸极限浓度的理论方法，该方法由可燃性气体的化学组成来推算上下限浓度，不需要其它条件；对混合工质制冷剂，只要再知道混合配比，即可以推算出爆炸极限，使预测爆炸极限的工作更简单、方便。

The latter is essentially derived from the geometric realization of Happels triangulated equivalence between stable module category of repetitive algebra and bounded derived category of finite dimensional algebra. In terms of this realization, we deduce that the Lie algebra realized by derived category of a finite dimensional algebra is isomorphic to the Lie algebra realized by stable module category of the corresponding repetitive algebra.

后者本质上是Happel关于重复代数的稳定模范畴和导出范畴的三角等价的一个几何实现及其应用，使用这种几何实现，我们可以证明在重复代数的稳定模范畴上定义的李代数同构于相应的导出范畴上实现的李代数。

The historical journalism opens out that they are similar in their frameworks,consistent in their hypostasis,and uniform in their significance between the furthermost one and the latest one.

历史新闻学揭示了最远的东西与最近的东西在结构上是统一的，在本质上是一致的，在意义上是相同的。

We prove that in every induced locally compact 〓fuzzy topological groupthere exist at least one regular fuzzy set-valued Haar measure.We define the fuzzymeasurable group and prove that the fuzzy set-valued Haar measure in a fuzzymeasurable group is essentially unique.We also construct the fuzzy topologicalstructure on a group by the fuzzy set-valued measure such that make it a fuzzytopological group.

证明了诱导局部紧〓模糊拓扑群上存在模糊集值Haar测度，定义了模糊可测群，通过对模糊可测群的研究证明了诱导局部紧〓模糊拓扑群上的模糊集值Haar测度本质上的唯一性，并利用模糊可测群上的模糊集值测度构造了群上的模糊拓扑结构使之成为模糊拓扑群。

Digging the basic motives of heroines" behaviors from their psychodynamics can been seen as the depth which SiMaqian reached on heroines" psychodynamic exploration; the digging in true nature and character can be seen as the height SiMaqian reached on the height which is not in general meaning but in humanity.

对人行为动力的分析，也就是从本质上、本性上对人的探掘，因此，司马迁在这方面的分析，已不是普通意义上的人物心理的研究，而是上升到了传主人性的高度。这可以说司马迁在人物心理的探掘上所达到的高度。

The reason "It is 5 o'clock on the Sun" cannot be explained as "It is the same time as it is when it is 5 o'clock on the Earth, only on the Sun" is that clock-timings carry essential reference to the Earth.

在太阳上5点"不能被解释为"这是和地球上5点一样的时间，只是是太阳上的，理由是'时钟时间'本质上是地球上的指称。

With the methods of experimental comparison and mathematical statistics,this paper makes the comparison between Star teaching model and traditional model.The main purpose is to discuss the better teaching model with the comparison,analysis,and induction of statistical data in three tests.The results show that there are more validities and rationality of Star model in the aspects of the effect of study,quantification of teaching,comparative analysis.

经过文献资料的比较和分析，现代定向越野运动无论在技术教学的基本观点上还是在技术的外形和内涵上都有了新的变化和发展，但方法还是比较单一，且大部分采用的是定性分析方法，分析体能、技能的构成、比重时只着眼于整体，一定程度上不够确切，不能细化地作定量描述，因而，学生对技术的分析、认识也必然带有相对的模糊性，不可能从技术的本质上作深入的分析，进而有效地解决问题。

The creative industry is the result of creativity"s commercialization and marketing in the knowledge economy time. C. Giving a definition of creative industry by philosophy which says "it is the industry to put creative products commercialized and valued through creative work, and the result of mixing of economy, culture and technology. The mixing of creativity, culture and technology is the general characteristic of creative industry.

把创意产业界定为&运用创新劳动把创意产品商品化并形成价值的产业，是经济、文化和科学技术相互融合的产物&；把创意产业的基本特征归纳为创意劳动在本质上的原创性、在创意手段上的数字化、在创意组织上的网络化和在产品表现形式上的智能化，提出了创意、文化、科技三者的融合是创意产业的总体特征，这一总体特征是创意产业与其他产业相区别的明显标志。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。
