1引言在工程结构的可靠性分析中，一次二阶矩法(包括中心点法、JC法、映射变换法和实用分析法)以及二次二阶矩法得到了广泛应用[1，2]。

We establish a relation between μ and the stucture of the group G, and obtain the lower bound of the ratio by the mininal prime divisor of the order and commutator of the group G, and give a necessary and sufficient condition under which this lower bound is attained.

第一部分，记有限群G的阶与不可约特征标个数的比值为μ，我们研究了一般的非交换有限群G的结构和μ之间的关系，通过群G的阶的最小素因子和换位子群G′的最小素因子得到了μ的一个下界，同时给出了达到下界的一个充分必要条件。

In this Chapter, we establish convergence theorem by using the majorizing method.

第二章，提出了一族具有三阶收敛迭代法，这族迭代法避免了求F的二阶导数。

Spatial white noise is considered first then the spatial colored noise. Two method based on 1st and 2nd order cyclic moments, CERA, and then 3rd order cyclic moment, MCERA, are proposed separately.

分白噪声及有色噪声两种情况，分别提出了基于一、二阶循环矩的CERA方法和基于三阶循环矩的MCERA方法。

The factorial of a number is defined as the product of all values from one to that number.

阶乘。 一个数的阶乘被定义为从 1 到该数字所有数字的乘积。

According to one embodiment, the at least one filter includes a plurality of 2.sup.nd-order filters connected in series, and an output from each of the plurality of 2.sup.nd-order filters are scaled and summed to provide the false flow signal.

根据一项体现，是至少有一个过滤器包括一个多元化的2.sup.nd阶滤波器串联，和一个输出从每一个多元化的2.sup.nd阶滤波器的规模和总结提供虚假的血流信号。

As to the Power Ground RLC equivalent circuit with a large number of independent current sources, we propose a novel HOAR based MOR method.

在电源地网络RLC等效电路降阶分析方面，我们提出了一种新的基于高次Arnoldi过程的降阶算法HOAR。

Its subordinate relations,include relations,the order of starlikeness and the order of strongly starlikeness as wellas the integral represation theorem, etc.

引入了强星像函数类的一个子类S（α，β，ρ，σ，A，B），讨论了它的从属关系、包含关系、星像阶数和强星像阶数以及积分表示定理等，所得结果推广了一些作者的相关工作。

For the sake of accurately estimating the contact force, we describe a new method, in which the contact force is considered as a jump function of time, and by use of response to jump function, the history of impact force is detected in the duration of rotor contacting with stator.

为更准确地获得接触作用力，本文将接触过程中转子所受作用反力函数视为在微小时间间隔下的阶跃函数，提出一种计算接触作用力的新模型，利用系统对阶跃函数的响应可以得到转子与定子碰摩时的切向摩擦力与法相作用力的时间历程及相应的位移、速度量。

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。
