SQUA genes of Dendrocalamus latiflorus were sequenced, and phylogenetic form on SQUA genes in angiosperms was analyzed. Relative rate and adaptive evolution after SQUA gene duplication in recent common ancestor of monocots and eudicots were analyzed using the methods of relative rate test, statistic on synonymous and non-synonymous coden substitution sites and likelihood rate test.

测定了麻竹的SQUA基因序列并分析了被子植物中SOUA类基因的系统发育式样；采用相对速率检验、同义与非同义置换位点统计以及似然比检验方法，分析了单子叶和真双子叶植物最近共同祖先中SQUA基因发生基因重复后的进化速率与适应机制。

The duplication and synthesis of DNA and RNA in tumor cells are restrained after Glycyrrhiza flavonoids binding with them.

甘草黄酮与肿瘤细胞DNA和RNA结合后抑制其进一步复制与合成，可能是其抗肿瘤作用的途径之一。

HaNPV is the earliest commercial baculovirus insecticide in China and about 100, 000 hectare cotton farmland had been used such insecticide to prevent Heliothis armigera by the end of 1999. Many aspects of HaNPV such as the isolation and identification of different virus strains, bioassay of their toxicity, infectivity and duplication in culture cells, genome sequencing and some functional genes have been researched.

国内已对HaNPV进行了多方面的研究，包括病毒株的分离鉴定、形态特征、病毒生物活性测定、离体细胞感染和复制、测序和功能基因研究，基因工程病毒杀虫剂的构建等；但对其复制侵染与宿主细胞互作的分子机理，目前仍缺乏足够且深入的了解。

It is the research of the hypercycle theory about molecularevolution that attempts to give a description of kinetics which describes themolecular duplication's mechanism of historical process.

而超循环论的分子进化过程的研究，就是给出分子复制形成过程的动力学描述。

After extraction by ethanol and purification by cationic ion-exchange column, a method of using reversed-phase high-performance liquid chromatography and precolumn derivatization with o-phthalaldehyde and 9-fiuorenylmethylchloroformate is employed for determination of free amino acids in tobacco . This method assures that amino acids with amino and imino groups can be determined simultaneously. The results of duplication experiment and recovery experiment are acceptable.

本试验用乙醇提取烟叶中的游离氨基酸，并用阳离子交换树脂纯化，再用邻苯二甲醛、氯甲酸芴甲酯联合柱前衍生、反相高效液相色谱分析测定了烟叶中的游离氨基酸，该方法能同时测定烟叶中的带氨基和亚氨基基团的氨基酸，并且分析方法的重现性和回收率均令人满意。

Subcutaneous layer of the root of the second, third whisker in the third row and nervus ischiadicus on one side of 40 normal Wistar rats were stimulated by electricity, TEP and IEP were detected from the contralateral epidural surface, and the detection rate, stability and duplication of waveform were compared.
