Based on these simulation results ,specify the distance between the pads and the CPWis 150μm ,the number of the thermocouple is 50 ,the distance between the CPWand the thermo2pile is 50μm. GaAs and Au are chosen as arms of the thermopile ,and TaN as the terminal resistor.

根据这些模拟结果，传感器中接触垫与共面波导之间的渐进区长度设计为150μm ，热电偶的对数设计为50 对，热电堆与CPW之间的距离设计为50μm ，并选择了GaAs 和Au 作为热电偶的两臂，TaN 作终端电阻。

The calculated results of transmission coefficient indicate that this new method can be applied to compute photonic crystal and total internal reflection.

透射系数的计算结果表明，这种新方法可以很好的用来计算光子晶体禁带以及普通的全反射，对于研究一维光子晶体波导非常方便。

During numerical integration the triple integral is time consuming and divergent when the number of higher waveguide modes increases.

本文首先建立波导宽边中心倾斜孤立辐射裂缝的积分方程，然后用矩量法求解得到了孤立缝的S参数及归一化等效阻抗。

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。
