主要加工PCB (普通模具、硬性模具、复合模具、精修模具、铝基模具)、FPCB模具、五金模具、加工配套的冲床模具脱模器、五金机加工及PCB周边设备、非标设备设计、制作。

In PEC trimers, the energy transfer paths in PEC monomers remain, but the transfer rates between the chromophores become higher due to strong couplings between pairs of the nearest neighbor chromophores 1α〓-PVB/2β〓-PCB. Meanwhile, a new energy transfer path with a time constant of about 40 ps emerges among the three β〓-PCB chromophores of C〓 symmetry in PEC trimers.

在PEC三聚体中，在相同单体中的能量传递途径仍存在，由于三聚体毗邻的1α〓-PVB/2β〓-PCB色团对之间的强耦合，使不同色素之间的能量传递速度加快；同时，在PEC三聚体中出现新的能量传递途径：3个具有C〓空间对称性的β〓-PCB之间所发生的较快速的能量传递（约40 ps）。

采用SMT工艺产品的设计，要先从确定产品工艺流程，再通过元器件的选择，贴片元器件在PCB中的布局，以及SMT设备对PCB的要求等内容来介绍设计中的要素，帮助设计者能更好地设计。

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。
