聚丙烯

The results of CRYSTAF test showed,along with the increment of the ethylene content,an increase in the tacticity of propylene homopolymers and decreases in the isotacticity、long crystallizable sequence content.

结晶分级分析测试结果显示，随着乙烯含量的增加，聚丙烯均聚物部分链结构规整性提高，结构规整、可结晶的长序列含量在减少，可见乙烯含量的变化规律直接决定上述参数的变化规律。

The antibacterial activities of most of fractions were similar to the pomegranate peel extract.(7) Respiratory inhibition experiment showed that the respiration of thallus was inhibited mainly through the hexose monophosphate pathway, which leaded to be short of NADPH, and induced metabolic function dysfunction. Growth curve assay showed that the pomegranate peel extract inhibited cytodieresis in logarithmic growth phase. After exposure to the pomegranate peel extract, bacterial protein was analyzed by SDS-PAGE. The results showed that protein synthesis was inhibited, especially for large molecular weight protein.

7呼吸抑制试验结果表明，石榴果皮提取物主要是通过抑制HMP途径，导致还原力NADPH缺乏，引起代谢功能障碍，达到抑菌的目的；加药组和正常组金黄色葡萄球菌生长曲线的对比结果表明，石榴果皮提取物能够抑制金黄色葡萄球菌对数生长期的菌体分裂；SDS-聚丙烯酰胺凝胶电泳分析表明，石榴果皮提取物能够抑制菌细胞蛋白合成，尤其对菌体内大分子量蛋白作用最明显。

The catalyst used diethyl 2,3—di—i—propylsuccinate as internal donor particles were also synthesized.

The research displayed that yeasts Genus level can be discerned by agarose gel electrophoresis and polyacarylamide gel electrophoresis, but the latter is more advanced. The Saccharomyces cerevisiae strains ITS-1 sequences are most disalike, few of them are equal completely. The bigger differences are part of base pairs about Poly-T, others are exchanged by single base pair.

研究表明，以酵母菌株的rDNA ITS-1序列进行琼脂糖凝胶电泳，能把菌株分类鉴定到属的水平；采用非变性聚丙烯酰胺凝胶电泳能把部分酿酒酵母菌株分类鉴定到种的水平，区别效果较琼脂糖凝胶电泳有所提高；对rDNA ITS-1序列进行克隆、测序，经序列比对后发现，酿酒酵母属中酿酒酵母菌株的ITS-1序列大多数有差异，差异主要表现在ITS-1序列上游的一段Poly-T碱基上，其它处的差异仅是个别碱基的转换或颠换，ITS-1序列长度分布在360-370bp之间，G+C%含量均在35.3%左右。
