Ladies and gentlemen, since we have started our mission to diminish the use of dangerous biocides, we are widely considered as pioneers in the development of a revolutionary chlorine dioxide material being used for water disinfection and /or water treatment as an alternative to chlorine and chlorine-type disinfectants, which are detrimental to health and environment.

女士们，先生们，自从我们开始我们的使命，减少有害生物杀灭剂的使用，我们就带头开发含有二氧化氯的化学物质，并将之运用于水消毒和水处理中，以取代对健康和环境不利的氯气和氯基杀毒剂。

The one carbon unit transfer reaction involving in the tetrahydrofolate coenzymes has caused great interest which is very important in the living system and has played an important role in the designing and syntheses compounds (especially the anti-cancer and LCD materials). In our study it was found that benzimidazolium salt has the ability to transfer one or two one-carbon unit and is a kind of new tetrahydrofolate coenzymes model. This research provides new method for biomimetic synthesis.

在非酶催化条件下，不仅实现了与生物体内相类似的一碳单元转移反应，而且可以转移具有不同官能团的取代&一碳单元&，使这种一碳单元转移反应传递的功能化一碳单元更加多样化，这方面强劲的研究工作进展，将为异常活跃的合成化学提供更多常规合成方法难以实现或实现不理想的仿生合成新方法。

Physical, chemical and biological agents were main elicitors being applied, which can change morphology, physiology and biochemistry to improve the natural disease resistance.

There were a great deal of kinds of the grass with high quality and quantity fed to fish To determine the best symbiosis ecosystem of fish and grass on a closed system circulated yearly, several cold and warm grass was selected to analyse the adaptability and nutrition absorbed. It indicted that Lolium multiform Lam. and lemarthria compressa were the best option due to high adaptability of wetness, high coarse protein, fat and fibre and so on in the leaf, high biomass, high bio-filtration effect of N and P, adaption to the low or high temperature, resist to the plant diseases and insect pests, and the food of fish whose forage was grass.

鱼用优质高产牧草的种类繁多，为确定最佳的鱼草共生周年循环系统，本文选择几种冷季牧草和暖季牧草进行生长适应性与营养吸收研究，分析表明，多花黑麦草和扁穗牛鞭草是最佳的冷季牧草和暖季牧草，它们耐水性强，叶片中所含的粗蛋白、粗脂肪、粗纤维等化学成分高，植株的生物量也高，生物过滤养殖废水中的氮和磷效果好，而且可以适应外界环境的低温或高温，抵抗病虫侵害，同时为草食性鱼类喜欢食用。
