Self-assembly of PEO-b-PB (M〓of PEO=5100 g/mol and M〓 of PB=5100 g/mol) and poly (PAA, M〓=2000 g/mol) was obtained in THF/dodecane mixtures via PEO/PAA complex. The effect of ratio of PEO-b-PB: PAA was investigated.

通过PEO-b-PB（PEO和PB分子量均为5100g／mol）中PEO链段和聚丙烯酸（PAA，分子量为2000g／mol）的氢键相互作用，我们在THF／正十二烷混合溶剂中获得了PEO-b-PB／PAA的自组装体，并研究了PAA用量对自组装行为的影响。

In regulating blood sugar experiment,the polysaccharide of Enteromorpha could decrease the concentration of the diabetes mices which was caused by tetraoxypyrimidine.

在调节血糖的试验中，桑黄菌丝体多糖能降低链脲佐霉素所导致的糖尿病小鼠的血糖浓度。

In this paper, an escherichia coli-saccharopolyspora erythraea shuttle vector containing the erya promoter region was constructed using the enhanced green fluorescent protein gene as a reporter. the shuttle plasmid was transformed into sac.erythraea a226 and streptomyces lividans jt46 by peg mediation, respectively. fluorescence microscopy confirmed that the egfp was expressed in both strains.

本文克隆了erya基因的启动子perya，以绿色荧光蛋白基因为报告基因，构建了大肠埃希菌-糖多孢红霉菌穿梭型质粒。peg介导原生质体转化法将穿梭型质粒分别转入糖多孢红霉菌a226与变铅青链霉菌jt46，荧光显微镜检测发现，此启动子在两菌株中都具有功能。

We have synthesized fourdioxotetraamine ligand appended with fluorenyl group and their transition metal complexes.The crystal structures of the complexes were determined by x-ray diffraction. Stability,electrochemistry and switch properties in aqueous solution was studied by pH-potentiometricand fluorimetric titration as well as cyclic voltammetry.

合成了带侧链荧光基团—芴的二氧四胺配体及其过渡金属配合物，测定了过渡金属配合物的晶体结构，研究了他们在水溶液中的稳定性、电化学性质和荧光开关性质。

Six thermophilic bacteria were isolated and purified from a hot spring in Chang-bai mountains,One of those morphology has been studied detailedly,it's growth course has been observed,we find it's morphology is very peculiar,at different growth phase,it's morphology changed very evidence,in the logarithmic growth phase,the cell is rod, majority cells are single existence,minority are geminous or a long discontinuous chain,in the middle growth phase,rod and globe are concomitant,in the late stationary growth phase, the cells change to globe.

从长白山中一个温泉里面分离，纯化出来六株高温菌，我们对于其中一株CW2的个体形态做了详细的研究，对它的生长过程连续监测，发现它的个体形态比较特别，在不同的生长阶段，它的个体形态变化非常明显。菌体在对数生长期初期是杆状，大多数单生，少数对生或者形成间断的长链，在中期就是球形和杆形共存，在对数生长期的末期基本上是球形。
