The main work of this dissertation is constructing Arabidopsis gain of function mutants pool, screening mutants related to plant defense response, cloning the genes and studying their functions. The main results are as following:(1) Arabidopsis in planta transformation were made by Agrobacterium tumefaciens carrying the activation tagging vector pSKI015 with herbicide-resistant Bar gene as a selective marker. About 12000 independent transformant lines were acquired by the above method from which two mutants related to plant defense response and development, asr1 (auxin and salicylic acid responsive 1) and dai1 (drought tolerant and abscisic acid insensitive 1) were isolated.

To express chicken osteoprotegerin in Pichia pastoris and determine its inhibitive effects on mature osteoclastic bone resorptive function in vitro. The chOPG cDNA encoding for 382 amino acid without signal peptice was subcloned into Pichia pastoris expression vector pPICZα-A. The constructed plasmid was transformed into yeast X-33 by electroporation. The recombinant transformants were selected by Zeocin. Induced by the addition of methanol every 24 hours, the product analyzed by SDS-PAGE was sized about 43kDa and 53kDa at a yield of 200mg per litter of culture. The result of Western blotting indicated that the recombinant protein had specific antigenicity mainly owing to heterogeneous glycosylation.

为了在毕赤酵母中分泌表达鸡骨保护素（osteoprotegerin，OPG），采用DNA重组技术将chOPG成熟肽cDNA片段插入毕赤酵母表达载体pPICZα-A中，以电穿孔法转化酵母X-33，用Zeocin 平板筛选重组子，经甲醇诱导表达后， SDS-PAGE 和免疫印迹分析表达产物，由于糖基化不同，表达产物有两种，其相对分子量分别为43kDa和53kDa，表达量约为200mg/L，经Western印迹验证，有较好的抗原性。

Also, because the setweight function marks all lexemes of the given vector the same way, it is necessary to parse the text and do setweight before concatenating if you want to label different parts of the document with different weights.

还有，因为 setweight 函数给同一个给出的向量里的所有语意做同样的标识，所以，如果你想给文档的不同部分加上不同的权重，那么我们有必要先分词，然后在连接之前 setweight。

According to the equivalence of traffic forecasting and function estimating and approaching,the essay puts forward a method of short-term traffic forecasting which is based upon wave decompounding and support vector regress.

基于交通流预测问题与函数估计和逼近问题是等价的的思想，提出一种基于小波分解-支持向量回归的短时交通量预测方法。

For 2p〓-periodic binary sequences, a new weight function, according to the above presented vector expression of the linear complexity, is defined. By analyzing the weight of the product of a special kind polynomial in finite field, the upper and lower bounds on minimum error, expressed by the here denned weight of the linear complexity, are given in different cases.

对于2p〓-周期二元序列，利用所给出的线性复杂度的向量表示定义了一种新的重量函数，通过研究有限域上一类特殊多项式乘积的重量，分情况给出了用线性复杂度的重量表示的最小错误minerror的上界和下界，这里的重量是由我们所定义的重量函数确定的。

It could be useful for the further study of NS1 gene function. Method The NS1 gene of H5N1 subtype AIV was amplified by RT_PCR and cloned to pGEM_T_easy vector. The NS1 gene expressing plasmids was constructed by inserting the target gene fragments into pGEX_4T_1 vectors. The expression proteins were indued by IPTG and analysed by Western blot.

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。
