查询词典 number system

Since the nonholonomic constraint constrains the time derivatives of the generalized coordinates of the system and does not reduce the degree of the system configuration freedom, the number of the dependent control inputs is less than the degree of the system configuration freedom, which leads to a difficulty in controller design.

由于非完整约束是对系统广义坐标导数的约束，它不减少系统的位形自由度，这使得系统的独立控制个数少于系统的位形自由度，给其控制设计带来很大困难。

According to the existence results of general equilibrium problems and vector equilibrium problems have been studied more and more. Inspired and motivated by these research results, this paper is devoted to study systematically a class of equilibrium problems, which is unify and extension of a large number of known equilibrium problems and variational inequalities problems. The research is carried on from three aspects.Firstly, in finitely continuous topological spaces, we introduce four new types of the system of generalized vector quasi-equilibrium problems, and we derive some existence results of a solution for the system of generalized vector quasi-equilibrium problems via the maximal element theorems in product finitely continuous topological spaces.Secondly, in complete metric spaces, we provide the Ekeland variational principle to equilibrium problems with set-valued maps. And via the Ekeland variational principle, existence results for vector equilibrium problem with set-valued maps and the system of vector equilibrium problem with set-valued maps.

针对一般的均衡问题和向量均衡问题解的存在性，已有许多研究成果，受这些成果的启发，本文主要从理论上较为系统地研究了一类均衡问题，它统一和推广了许多已有的均衡问题和变分不等式问题，研究分有三个方面；首先，在有限连续拓扑空间中，我们提出了四类广义向量拟均衡系，并借助于有限连续拓扑空间中的极大元定理讨论了这四类均衡系问题的解的存在性问题，然后，在完备度量空间中，我们给出了关于集值均衡问题的Ekeland变分原理，并利用Ekeland变分原理分别讨论了集值向量均衡问题和集值向量均衡系问题的解的存在性。

The motives for his introduction of an astronomical system different from that of Schall could also be two-faceted. Firstly, under the influence of the dispute between Lansberge's Copernican school and the Tyconic school in Europe, he apparently became a sympathizer of Lansberge's system. Secondly, being quite aware of the serious errors of Tychinic astronomy in some calculatoins, like a number of other Jesuit Fathers doing, Smogulecki was pobably trying to replace it with Lansberge's system, which he believed to be more exact.

至于他为什么要介绍一种不同于弟谷体系的天文学系统，原因也有两个方面：首先，他明显受到当是欧洲哥白尼和弟谷两大天文学派之间的论战的影响，并且对哥白尼学派的主张持同情态度；其次，于许多入华耶稣会士一样，穆尼阁很明白，弟谷体系在天文计算中仍然存在很大误差，所以想用他认为更加精密的兰斯伯格的天文学系统来对它加以取代。

Therefore,it is necessary for us to conduct a series of principle analysis on different sections of the station such as the fuel system,lube system and cooling system of the diesel engine for generators,and the shaft generator as well as the main switchboard etc. It is also important to carry out at meantime a number of reliability tests and analyze the test results so as to assure all the units of the station will run smoothly.

因此，我们通过对船舶电站中柴油机的供油系统、润滑系统、冷却系统、轴带发电机、主配电板等各个环节从原理上进行分析，并进行必要的可靠性试验，对试验数据进行分析，确保船舶电站各个环节的运行良好。

If constructing the ifg of system based on the source code of the system directly,it may produce a great number of information flow paths not existing in the system for the reason of the transitivity of the information flow.

利用程序依赖图先处理系统信息流中的传递关系，然后再进行信息流图的生成，从而减少引入系统中不存在的信息流路径，减少信息流分析时的工作量。

In fact, on one hand, it is often found that two graphs with the same number of verticesand the same connectivity(edge-connectivity) may result in entirely different forms after a minimum disconnecting set of vertices is removed, one may be totally disconnected while the other may consist of a few very stable components, and thus be much easier to reconstruct.On the other hand, we often face this question: how easily can we disrupt a system at the least cost, on the contrary, when we set up a system, especially a communication system, we try our best to make it as stable as possible that it can be reconstructed easily if it do get disrupted .

对于两个具有相同点数，具有相同点连通度的图，从图中分别去掉使图不连通的点集后，所得图的结构可能完全不同，这是因为点连通度、边连通度和局部点、边连通度等连通性参数仅反映了系统被破坏的难易程度，而对系统遭受破坏的程度并没有明确的反映。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
