In case of high input dimension system model, taking norm of input vector as the input of wavelet network instead of using tensor product method to construct wavelet network ,which could solve the problems of high computation and curse of dimensionality.

在模型结构方面，对于多维输入输出系统建模，本文放弃选用传统的标量积确定小波基函数的方法，将输入矢量的范数作为小波网络基函数的输入变量，从而避免了高维输入所带来的可用小波基数量巨大和计算复杂的缺点。

Total RNA was isolated from cultured human pigmental cells and mRNA was reversly transcribed into cDNA. Then PCR was used to amplify the TRP -2 coding region. The PCR product was cloned into pUC19 plasmid and sequenced, then subcloned into vector pGEX-4T-1. The TRP-2 protein was expressed hi E coli of DH5 a as fusion protein with glutathioneS-transferase induced by IPTG. The fusion protein was purified by glutathione resin column.

我们通过RT—PCR的方法扩增TRP—2编码基因，克隆至pUC19载体并测序，再亚克隆至GST融合表达载体pGEX—4T—1，转化大肠杆菌，IPTG诱导表达了GST/TRP—2融合蛋白，并分析鉴定表达蛋白的可溶性，最后第四军医大学硕士学位论文一用谷氨酚胺树脂柱纯化表达的蛋白。

In order to efficiently handle multi-constraints, a vector function inner product is defined in the zero level set and a gradient projection method is constructed, and the necessary condition satisfied by the optimal solution is proved.

一个赝矢量和一个矢量的标识称为赝标量。

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.
