转移核糖核酸--核糖核酸的一种，当蛋白质合成时，当氨基酸与信使核糖核酸的转接器。

In this paper, problems of trend test in clinical experiment are studied mainly by the statistical inference method under order restriction. The ori- gins of order restricted statistical inference are usually dated back to the early 1950s. At about the same time, a number of researchers started working inde- pendently on similar problems. The field developed rapidly during the 1960s and early 1970s and formed the more perfect theory of estimation and test- ing.

The development of military affairs technic of Taiwan is special, the special political requirement inside and the complex international relation make its , ilitary by thought of "Taiwan independence", So its military affairs technic is restricted by the need of weapons for a long time, and badly depend on the environment, Especially restricted by Aamerica, which make a kind of deviant need draught and dependency, Because of restriction its politics, economic strength, sources and international environment, Taiwan cannot sustain a perdure war, to improve the short time battle effectiveness because the first aim of military affairs technic has many shortcoming.

由于台湾自身政治、经济实力、能源资源以及国际环境的局限，台湾并不能够承担持久战，所以提高短期战斗力成为台湾军事技术发展的中心目标，而其军事技术发展的直接目标表现为武器获得。

The Charon library DNA was then digested with restriction enzymes BamH Ⅰ and Hind Ⅲ, and DNA fragments of length of about 0.5-1. 5kb was subcloned into plasmid pUC 18 which was also digested by BamH Ⅰ and Hind Ⅲ and dephosphorylated by alkaline phosphatese before being ligated with Charon fragments.

抽提λCharon文库总DNA，用BamHⅠ和HindⅢ完全酶切电泳，用低熔点琼脂糖回收长约0.5-1.5kb的DNA片段；连接到pUC18上，pUC DNA先用BamHⅠ和HindⅢ酶切，后用碱性磷酸酯酶脱磷。

With the"phototactic effect"ofthe advanced technology wars hard to be eliminated in a short time and presenting the ten-dency to develop long,the effective way to settle the contradiction between the great cost ofthe advanced technology wars and rigid restriction of resource supply is only to raise the effi-cacy of the advanced technology wars.

In the present study, the effects of food restriction on the growth, survival and metamorphosis of Pinctada fucata were investigated from April 27 to May 25 in 2009 under different feeding conditions.

自2009年4月27日至2009年5月25日，在不同投饵条件下研究了限食对合浦珠母贝幼虫生长、成活和变态的影响。

Restriction map of H. polymorpha CBS 1976 chromosomal locus containing △9-fatty acid desaturase gene was constructed based upon the data of Southern analysis, and a 3. 4kb BamHⅠ-XhoⅠ genomic fragment was isolated. Sequence analysis showed that it contains an ORF of 1353bp with high homology with cloned yeast △9-fatty acid desaturase genes.

构建了H.polymorpha CBS 1976染色体△9-脂肪酸去饱和酶基因座位的限制性酶切图谱，进而分离了3.4kb BamHⅠ-XhoⅠ基因片段并进行全序列分析，结果表明这个片段含1个与已克隆的酵母△9-脂肪酸去饱和酶基因高度同源的、由1353bp组成的ORF。
