Methods: Using GV1 and GV2 targetable non-viral vectors, the influences of the poly-L-lysine and protamine on in vitro gene transfer efficiency and the course of gene expression were observed. Results:β-galactosidase was expressed at intermediate level (50%) in A375 cells using a complex containing either protamine or poly-L-lysine.

目前，大部分受体介导的靶向性非病毒载体都利用多聚赖氨酸作为骨架分子来包裹DNA形成复合体，并在实验室研究中取得了较好结果，但由于多聚赖氨酸的临床安全性未知，难以应用于临床研究。

As with vectors, reading more than one matrix component is called swizzling.

和向量异向，读取多个矩阵通道叫做 swizzling 。

The geometric character of the support vector is used to extract the simples,which can be the support vectors possibly from incremental simples.

实际应用中，由于样本的采集往往是不断积累，不断丰富和完善的，经常有新的样本加入。

The particular parameters of interest,B and b,may be scalars or vectors.

这有让人感兴趣的特定参数，B和b，可能是标量或矢量。

As is discussed in Section 4.2,the material derivative operator may be applied to scalars or vectors.

如同在4.2节里面讨论过的，物质导数运算符或可应用于标量或矢量之上。

Vectors can be used to represent physical entities such as forces , and they can be added to each other and multiplied with scalars , thus forming the first example of a real vector space .

矢量图可以用来代表物理实体，如部队，它们可以被添加到彼此乘以与标，从而形成了第一个真正的向量空间。

The emergence of drug resistance of the parasite and development of resistance of Anopheles mosquito vectors demands a search for new tools to control the disease.

疟原虫抗药性的产生和迅速扩散以及抗杀虫剂蚊媒的出现和蔓延迫切需要我们寻求新的疟疾防治措施。

We successfully constructed the recombinant retroviral vectors of NHE-1 specific hammerhead ribozymes and transfected them into the PASMCs in vitro.

1。本实验成功地构建了大鼠NHE-1特异性锤头型核酶的逆转录病毒载体，并成功转染入培养的PASMCs内。

Gene trap elements are also used in the construction of retrovirus vectors.

基因诱捕技术也被运用了反转录病毒载体的构建。

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。
