The system is characterised by 2x5.25 woofers and a dome tweeter with a SWGH in a WTW configuration.

EDGE25PB由 2 个 5.25 英寸的低频单元和一个 SWGH球面波导号筒高频单元组成。

Then it gives a brief review and summary of electromagnetic theory of optical waveguides.

在调研的基础上，着重对非线性波导的传输特性进行了研究。

We can help solve such as waveguides, optical fiber of electromagnetic computation.

可以帮助我们解决比如波导，光纤中的电磁场计算问题。

Numerical examples are provided for various waveguides to show the validity and effectiveness of the method.

为了验证该方法，以三种不同的波导为实例进行了计算。

The influence of mutual coupling along with the distance and frequency between two open-end waveguides is discussed in this paper.

文中对两个开口波导间随距离及频率变化的互耦影响作了讨论。

In the center portion of the output end, the output waveguides are directly connected to the output end.

在输出端的中心部分，输出波导直接连接到输出端。

The results can be used to design and fabricate the low loss α phase single mode waveguides.

研究结果可供低损耗α相单模波导的设计和制备做参考。

So it is quite necessary to study in the area of the nonlinear effect in waveguides.

现在对于各种集成光电子器件和半导体激光器件的研究都要涉及非线性波导。

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。
