Then the surface of the star polymer was intramolecularly crosslinked using octa(3-azidopropyl)polyhedral oligomeric silsesquioxane, POSS-(N_3)_8,as the inorganic multifunctional crosslinker at high dilution concentration via click chemistry,forming a novel POSS/polymer hybrid nanostructure.Thermogravimetric analysis shows that after surface crosslinking, the thermostability of the core crosslinked PS can be remarkably improved.In the second work,we synthesized of a novel polymer with quatrefoil-shaped topology.

接着，我们合成了一种结构规整的含八个叠氮功能团的无机分子—多面低聚倍半硅氧烷，以其为交联剂，我们通过Click反应在即稀浓度下实现了前驱体星型聚合物的分子内表面交联，得到了外层为无机分子交联，内层为有机高分子的星状高分子，这种新型的星状聚合物表现出了优良的热稳定性能。

Biocontrol may be an alternative to avoid these problems in tobacco disease control. Ata28 strain is an antagonistic bacterium against tobacco brown spot was isolated from healthy tobacco in Chongqing.

Ata28菌株是从重庆烟区烟草健康植株上分离获得的烟草赤星病拮抗细菌，在PDA平板上可明显抑制烟草赤星病强致病力菌株Tbs3的生长，温室控病效果较好；为了进一步提高拮抗细菌Ata28菌株对烟草赤星病的防治效果，本研究采用紫外线、紫外线和氯化锂、硫酸二已酯及微波对Ata28菌株进行诱变选育，以期获得拮抗性能更强，生物学性状更好的优良菌株，为大田使用提供理论依据和实践经验。

Hyphal growth rate method was used to determine the inhibitory activities of chitooligosancharide against the pathogenic fungus of tobacco brown spot, Alternaria alternate Keissler, in the laboratory, and tobacco plants were applied with COS and its combinations like COS + Trichoderma + chitin with 5 treatments to control the disease under conditions of pot culture and inoculation in the greenhouse. Activities of 4 defensive enzymes, superoxide dismutase, polyphenol oxidase, peroxidase and chitinase, in tobacco plants were determined systematically at the same time within 10 days after application of COS and inoculation with the pathogenic fungus.

在实验室条件下，采用菌丝生长速率法测定了几丁寡糖对烟草赤星病菌的抑制活性，继而在温室盆栽和人工接种条件下，分别研究了几丁寡糖、几丁寡糖+木霉+几丁质等5种方法处理对烟草赤星病的防治效果，同时分别系统测定了烟草植株施用几丁寡糖及人工接种赤星病菌后10 d内SOD、POD、PPO和几丁质酶等4种防御酶的活性。

The metal abundance analysis gives that AG Dra is a CH star (poor metal Ba star, Pop Ⅱ member).

金属丰度分析给出AG Dra是颗CH星(贫金属钡星，星族Ⅱ成员)。

When using a star catalogue that is complete down to a certain limiting magnitude (i.e., the USNO-A2.0 or the UCAC ), a small number of stars (10 to 30) is usually sufficient.

当使用的星表是那种完全限定在某极限星等之下的数据的（比如：USNO-A2.0或UCAC星表），一个比较小的匹配星数目就一般足够了。

Until quite recently, the only useable catalogue for CCD observers was the Hubble Space Telescope's Guide Star Catalogue, that contains about 18 million objects.

直到目前，对于CCD观测者唯一合适可用的星表是GSC（哈勃空间望远镜的引导星参考星表），它包含1.8亿个目标。
