The result shows that:(1) the changing trend from center to edge of different level differs in three part,concussion very near the upper transmission line,increasing at first and then decreasing near upper and lower lines,and monotone decreasing other part;(2) the ±10% uniform field area of inner simulator is formed of two parts: one is the area with height of 20% to 85% and width of 80% from the center,the other is the area with height below 20% and width of 30% from the center.

仿真结果表明：从不同高度中心到边缘的场强变化趋势来看，最接近上传输线的位置为振荡，接近上下传输线的位置是先增大后减小，其余区域为单调减小；模拟器内部垂直极化场的±10%均匀场区域为模拟器传输线空间处于高度的20%-85%，宽度的80%区域，接近下传输线位置的高度的20%以下，宽度的30%以内。

The method of upper and lower solutions and the monotone iterative technique are used.

In the phase-separation process, the similar groove polymer "bulwark" can be easily formed between the rubbing moulage boundaries on fluctuating flexible substrates in the almost vertical rubbing direction.

研究发现，在相分离的过程中，与表面摩擦方向近似相互垂直的上下两柔性基板上的摩擦印痕边界之间易形成类似于槽栅状聚合物"壁垒"。

Children do as we do, not as we say, and down the road do we really want our children simply mouthing the word:"I love you" to us as they rush out the door?

儿童，因为我们做的，不是我们说，上下道，我们真的希望我们的孩子，根本看不出字："我爱你"，我们作为他们冲出门外？

See, it can even move up and down.

你看，他甚至可以上下转动

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。
