Use pCR2.1-TOPO and pCR2.1-Blunt II TOPO vectors as models, we investigated the possibility to use TOPO T/A vector (pCR2.1-TOPO) to clone blunt-ended PCR product and to use TOPO blunt vector (PCR-Blunt II TOPO) to clone 3'-A PCR product.

以pCR2.1-TOPO与pCR2.1-Blunt II TOPO载体为模型，我们研究了利用TOPO T/A载体（pCR2.1-TOPO）克隆平端PCR产物与利用TOPO 平端载体（pCR2.1-Blunt II）克隆3'-A末端PCR产物的可能性。

The mathematical model and working modes of a novel three-phase two-arm three-level neutral-point-clamped pulse width modulation rectifier suitable for direct-driving wind power system are analyzed in detail, and the constant frequency control strategies based on space voltage vectors are proposed and applied to the rectification conversion of direct-driven power generation system.

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.
