查询词典 elementary circuit

The elementary transformation matrix throughout the linear algebra theory has, it makes some of the problems of linear algebra, become more simple, makes it easier to understand, so elementary transformation in the role of linear algebra is very important.

标签：论文摘要，翻译，论文矩阵的初等变换贯穿于整个线性代数理论的始终，它使线性代数里的一些问题变的更加简单，使人更容易理解，所以初等变换在线性代数中作用十分重要。

As a result of myself interest hobby reason, myself have studied related computer aspect some elementary knowledge and the elementary operation eo, including Adobe Photoshop, Word and PowerPoint.

由于本人的兴趣爱好的原因，本人学了有关电脑方面的一些基本知识和基本操作，包括Adobe Photoshop、Word和PowerPoint。

When a truth-operation is applied to the results of truth-operations on elementary propositions, there is always a single operation on elementary propositions that has the same result.

对基本命题真值运算的结果再作一次真值运算，其结果总可等同于对基本命题施用某一单独的真值运算。

The elementary school teachers with different positions displayed significant differences in the satisfaction of "administrative support" in school administrative operation of elementary school toward Grade 1-9 curriculum.

三、任教年资的不同会影响教师对九年一贯课程学校行政运作的满意度。四、教师对九年一贯课程学校行政运作中「行政的支援」层面之满意度会因为担任不同的职务而有差异。

The elementary action group obtains the benefits of institutional changes by way of founding the secondary action group, using the method of conferring the licence rights. Certainly, the path that the elementary action group recognizes the licence rights is to study in this course. The course of institutional changes.

发动制度变迁的方式——初级行动团体通过次级行动团体来获取制度变迁的收益，其方式就是通过授予次级行动团体特许经营权，当然，在这个过程中初级行动团体是通过学习认识到了特许经营权这种方式。

The theory of elementary siphons has proved that a supervisorcan be computed and its size is linear with the size of the plant net model. But siphonenumeration is required for the purpose of determining a set of elementary siphons.

基本信标理论已从理论上证明可以得到与Petri网规模呈线性关系的受控Petri网模型，但在确定一组基本信标时同样受到枚举Petri网中所有信标问题的困扰。

As a result, the concept of an optimal set of elementary siphons is proposed and also the algorithm which can be finished in polynomial time to find such a set. With the set of optimal elementary siphons, net supervisors can generally produce maximalreachable states.

但是上述理论虽然只需要控制基本信标即可以控制整个系统，但是由于从属信标满足一定的可控性条件才能完全受控，这意味着在控制算法的生成过程中所有的信标都要参与，从而大大增加了系统控制的复杂性。

Different from the case of strict minimal siphons in a net system, the number of elementary ones is bounded by the smaller of place count and transition count. Based on the ideas mentioned above, this thesis proves that the set of elementary siphons is not unique, while different ones may lead to different control results.

本文在此研究的基础上，论证了网系统中的基本信标的不唯一性，控制不同的基本信标可以得到不同的控制效果，进而提出了最优基本信标的概念并给出了相应的计算方法，应用这一计算方法可以在多项式时间内求得一组最优基本信标，也就是说，控制该组基本信标相对于其他的基本信标可以使得系统Petri网模型具有最多的可达状态，这在实际中，意味着系统具有更大的灵活性。

As a foundation, the definition of elementary integral transformation and the method to factorize an integral matrix with elementary integral transformation is proposed firstly. After that, the problem how to find identification vectors in Modular-S-invariants is solved.

文中首先给出初等整数变换的概念，之后借助初等整数变换对整数矩阵进行分解，并在此基础上给出从加模S-不变量中求取不可达见证向量的方法。

This paper discusses such problems which are easily solved incorrectly in limitedteaching as, segment function is uncertain not to be elementary function, elementary function is un-certain to be continuous in its field of definition, unlimited variable is uncertain to be infinity, theinfinitely many infinitesimal is uncertain to be infinitesimal, the multiplication of two non- infinitesi-mal is uncertain not to be infinitesimal.

1分段函数不一定不是初等函数我们知道初等函数的定义是：常数和基本初等函数经过有限次的四则运算或复合，用一个解析式表示的函数叫初等函数。教材中的定义强调的"有限次"和"一个解析式"，使很多同学产生"非有限次"和"非一个解析式"的函数就不是初等函数的误解。例1f=ceox，s xx！0为分段函数，但也可以表示为f=e12(x-x2")+cos12(x+x2#"$)-1，故为初等函数。
