概念上的

Meanwhile, I have generalized the concept of trinomial property of sequence from binary case to arbitrary finite field case, and have proved that all the results in binary case are still hold in arbitrary finite field case.

同时，本文将三项式对的概念从二元序列推广到任意有限域上的序列，并证明了对二元序列成立的所有结果对一般有限域上的序列仍然成立。

Besides the introduction of concept about pyroligneous acid,the field of application,the key point is to expounding utilization status of pyroligneous acid in vegetable,crops,edible mushroom,livestock and poultry.,aimed at extending and study of pyroligneous acid in agricultural production.

作者除了介绍木醋液的概念、应用领域及发展历史外，重点阐述了木醋液在蔬菜、大田作物、食用菌和畜禽上的应用现状，旨在推动木醋液在农业生产上的推广应用和研究。

In ancient times, civil society is a concept that corresponds to the natural state .However, in modern times, Western thinkers have begun to put forward a concept of civil society which is set up based on the dichotomy of state and society, and to the contemporary, the people also began to use the trichotomy of s...

在古代，公民社会是一个与自然状态相对应的概念，但到了近代，西方思想家开始提出一种建立在国家和社会二分法基础上的公民社会观，而在现代，人们又开始用国家—市场—社会三分法来代替国家和社会二分法，并在此基础上重新界定了公民社会的内涵。

In this paper, we first give an example that the bilateral weighted shift operator in c_0space is hypercyclic operator and first solve the existence problem of hypercyclic operator in c_0or c_0(Z space . And then we investigate the property of weighted shift operator in c_0 space and an important property of the hypercyclic vector of weighted shift operator in c_0 space and c_0 space. At last we give the concept of weak hypercyclic operator and weak hypercyclic vector , and give the equivalence between the weak hypercyclicity and the hypercyclicity in l~1 space.

本文首先给出了c_0空间上的一个双边左加权移位算子是超循环算子的一个例子，首次解决了c_0 或c_0(Z 空间中超循环算子的存在性问题；接下来分别研究了c_0和c_0空间上的加权移位算子的性质以及c_0和c_0空间上的加权移位算子的超循环向量的一个重要性质，最后提出了弱超循环算子和弱超循环向量的概念，并且给出了I~1空间中弱超循环性与超循环性的等价性。

The in-depth analyses and simulation calculations of two simplification methods are carried out in this paper. Then it is pointed out that the equivalent d- and q-axes damper winding model is not suitable for calculating the internal short circuits because the concept is not applicable in this situation, and the errors caused by it are too obvious to be accepted in electrical engineering; while the approximate damper cage model is acceptable since it not only meets the accuracy requirement of electrical engineering but also saves calculating time for computers.

本文对阻尼回路的2种简化方法进行了深入分析和仿真计算，指出等效d轴和q轴阻尼绕组模型应用于电机内部短路计算时，物理概念上存在缺陷，且会造成过大的误差、在工程上无法容许；而近似阻尼笼的处理方法既能满足工程精度要求，又可节省计算时间。

Gas accumulation in shale is of many particular geological characteristics, some of which are self-generation and self-reservation, absorption accumulation, subtle aggregation, and so on.

与传统意义上的泥页岩裂缝气并不完全相同，现代概念的页岩气是主体上以吸附和游离状态同时赋存于具有生烃能力泥岩及页岩等地层中的天然气聚集，具有自生自储、吸附成藏、隐蔽聚集等地质特点。

Infourthgrade your idea of a good friend was the person who was willing to switch square dancing partners in gym so you wouldn't have to be stuck with the dork of the class.

上了四年级，你对好朋友的概念就是在体育馆里愿意和你交换舞伴的那个人，这样你就不必和班上的呆子一起跳舞了。

The African Union, the African equivalent of the European Union or Organization of American States is made up of both political and administrative bodies.

概念非洲联盟相当于欧盟或是一些美国所建立的一些国际的组织。都具有政治上和实体上的意义。

Young Einstein not bound by the old traditions, in the Lorentz and others on the basis of research work on the space and time to some basic concepts on the nature of the changes made.

年轻的爱因斯坦不为旧传统所束缚，在洛伦兹等人研究工作的基础上，对空间和时间这样一些基本概念作了本质上的变革。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
