The Brownian network which approximates a two－station multiclass queueing network with dynamic scheduling capability is extended to the case of multistation multiclass manufacturing systems and the appropriate algorithms regarding the input control and sequencing decisions are also developed.

2对于一般结构的制造系统，首次建立了可靠分析的一种线性多变量模型，模型阶数为工作站个数，模型变量为各工作站的实际平均加工时间，由此求得了系统的包括可靠性的稳态运行性能，解决了一般结构的制造系统的性能评估问题。

The non homogeneity of soil modulus along depth is taken into account. Then the flexibility coefficients can be obtained by solving Lagrange′s equation.

将地基划分为有限个水平层单元，位移函数表示为一次样条函数与Fourier级数的乘积形式，根据复阻尼理论的Lagrange方程，将问题归结为求解若干次低阶复代数方程。

Finally a stability criterion is introduced for linear non time-varying factional-order systems.

最后介绍了一种分数阶线性定常系统的稳定性判据。

With regard to the identical and non-identical parallel machine scheduling for minimizing the makespan, a hierarchical genetic algorithm was proposed.

针对最小化完工时间的等同和非等同并行多机调度一类问题，提出了一种递阶遗传算法。

To some degree,it is a genetic disease but environmental and other nongenetic factors clearly play a role in many stages of neoplastic process.

从某种程度上说，它是一种遗传性疾病，然而在肿瘤发生、发展的多个阶段里，环境因素及其它非遗传性因素也起到了明显的作用。

To some degree,it is a genetic disease but environmental and other nongenetic factors clearly play a role in many stages of neoplastic pr ocess.

从某种程度上说，它是一种遗传性疾病，然而在肿瘤发生、发展的多个阶段里，环境因素及其它非遗传性因素也起到了明显的作用。

Presents a new formulation of Lagrange s equations by using an augmented Lagrangian function with the first order non linear nonholonomic constraint equations, and offers a unified variational approach to both holonomic and nonholonomic constraints.

采用带有二阶非线性非完整约束方程的扩张性拉氏函数，建立起了拉格朗日方程的又一新公式，该新公式较为规则，它提供了一种完整约束系统和非完整约束系统两者统一的变分方法。

We find that the orthorhombic distortion leads to a secondorder coupling term between the d-and s-wave order parameters,which results ina nonvanishing s-wave component even in a uniform system and a mixed d+s-wave pairing state.

正交畸变使得GL自由能密度泛函中包含了d波与s波序参量的二阶耦合项。这一项的存在使得即使在空间均匀的情况下也会有非零的s波成分存在，并且导致d+s混合波配对态。

Partition search follows this strategy: construct a data structure for quick search and location, and divide the (K-1)th frequency itemset sequence into a number of continuous partitions to obtain a number of disjoint sub-sets of (K-1)th order frequency itemset.

分区查找基于以下策略：建立一种可快速搜索定位的数据结构，将频繁(K-1)-项集序列划分为若干连续的分区，形成(K-1)阶频繁项目集的若干不相交的子集。

A general Godunov finite difference schemes-WENO schemes which had fifth-order accuracy was used to make a numerical calculation for 2-dimensional axis symmetrical laser-supported plasma flow field under laser ablated solid target and laser ablated propulsion efficiency parameters(mechanical coupling coefficient etc.) was obtained by the simulation.The models of the calculation of ionization degree of plasma and the interaction between laser beam and plasma and the simplified eos of plasma were considered in the simulation.

采用针对高温气体电离度的一种近似计算方法，以及具有五阶精度的广义Godunov差分格式-加权本质无振荡格式WENO(weighted essentially non-oscillatory schemes)，给出了高温气体状态方程的简便描述，并考虑激光与等离子体的相互作用，模拟了强激光与固体靶相互作用时激光支持靶面等离子体流场的动态物理过程，并给出了不同参数条件下激光烧蚀固体靶的推进效应参数。

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。
