In the paper, the steady flow is also included to check the effect on the nonlinear forces with the different wave headings and different side-hull arrangements. From the comparisons of the theory and experiment, we find that the present technique can well predict the added resistance and lateral drifting force for the trimaran ship advancing in waves.

本论文将数值分析之结果与实验值做比较，来验证数值方法分析之正确性，并将稳态项、不同入射波波向以及不同副船体配置的影响加入考虑，来预估三体船在波浪中航行时的附加阻力和横向漂流力，从比较结果可看出本方法预估附加阻力及横向漂流力已有相当不错的结论。

Based on Douglas operators, the modified wide beam propagation is presented and the number dissipate is minimized without nearly increasing the memory and computing time. The method is also more stable and accurate than ordinary WBPM. Finally, A novel wide-angle low-loss dielectric slab waveguide Y branch is presented and analyzed by modified WBPM.

In order to survey the numerical diffusion induced by mesh rezoning and variables remap in ALE method,some calculations had been done,and comparisons show that the smoothing does exist,but the numerical dissipation is not serious,it do no harm to physical picture.

为考察ALE方法网格重分、物理量重映导致的数值扩散对计算精度的影响，进行了一些计算比较，结果显示，虽然存在一定程度的抹平现象，但是网格重分带来的数值耗散并不大，对物理图象并没有显著的影响。

On the other hand, a service provider may receive many requests at the same time, and because of the limited resources, it can't serve all of them. Consequently, for both service requesters and providers, there is a challenge of selecting interaction partners. This can be achieved by our proposed one-to-many service negotiation model.

在这个模型中，利用模糊命题表示协商参与者对服务的约束，这些约束是非数值化的；使用效用函数表示对数值化的服务非功能属性的偏好，采用二者相结合的方法建模对服务非功能属性的偏好选择。

Imperative languages typically have great tool support, debuggers, profilers, refactoring editors, unit test frameworks, and soon, and large standard numeric libraries that have been perfected over decades by domain experts.

命令式语言一般拥有丰富的工具支持，调试器，模具，重构编辑，单元测试框架，很快地，以及庞大的标准数值库，并且这些数值库已经过了领域专家们超过20年的验证。

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.
