A neural network approach for the constrained via minimization in multi-layer VLSI/PCB routing based on Hopfield network is proposed.

本文提出了一个基于Hopfield网络的VLSI/PCB多层布线中的有约束通孔最小化方法。

Rinted-circuit board air-core coils designed by using CAD tools and fabricated by adopting advanced PCB manufacturing technology are good in measurement accuracy and consistence of products parameters. But the characteristics of limited turns-density and large magnetic induction intensity grads on coil cross-section make great influence on the continuous uniform distribution of coil turns along the coil circumference and cause its discrete distribution.

CB空心线圈采用CAD方法设计和先进的PCB加工工艺制造，具有很好的测量精度和参数一致性，但是，线匝密度较小，而且截面上磁感应强度梯度较大，从而影响了线匝沿圆周均匀分布的连续性，使其具有了离散分布特征。

Contralateral spread and lumbar plexusblockade were assessed 15, 30, and 45 min after PCB.

评估 PCB 后15，30，45min 时向对侧扩散和腰丛阻滞效果。

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。
