This paper reviews pathways of aerobic and anaerobic microbiological degradation of PCP. It can be concluded that reductively dechlorination prior to ring cleavage plays a key role in mineralization of PCP.

文章通过综述好氧与厌氧微生物降解五氯酚的降解菌和降解途径，认为五氯酚首先通过脱氯转化为低氯代化合物后再开环，因此脱氯就成为五氯酚降解的关键步骤。

The catalytic cracking of NNJ 150 over USHY, HZSM 5 and SAPO 34 catalysts presented as that the selectivity of light olefins over USHY was the lightest among the three calalysts with a quicker deactivation, while HZSM 5 showed a longer catalyst life and lower selectivity of light olefins, for SAPO 34, both the conversion and the selectivity of light olefins were the lowest.

实现吸热型碳氢燃料这种功能的关键之一是选择适当的化学反应。由于碳氢燃料的裂化是吸热反应，而催化裂化与热裂化相比，能降低反应的温度，因此催化裂化是实现吸热型碳氢燃料功能较好的途径之一。由热力学可知，燃料裂化生成乙烯、丙

In this paper,functions of key enzymes in the biosynthesis pathway of shikimic acid were analyzed,and the breeding of engineering bacterium by genetic improvements for high yield of shikimic acid was also discussed.

简述了莽草酸生物合成的途径，着重从基因工程角度分析了莽草酸合成过程中的关键酶及其对莽草酸产量的影响，旨在为研究和开发微生物工程菌生产莽草酸提供参考。

In this process, I focus on refuting the arguments which believe social laws are either impossible, impractical, or ungainable. Finally, I aim to find a way to mitigate those a rguments: to weaken the concept of laws to unify laws and rules, and by this way do I want to support the coexistence of different methodologies.

本文以这三个问题为中心，挑选自然主义、反自然主义及多元论的几位典型代表人物的观点来展开论述，重点在于反驳坚持社会科学规律不存在、不实际或不可获得的观点，为化解关键争论找到一个途径：弱化&规律&概念，融规律与规则于一体，以期将此作为支持不同方法论的存在的突破口。

Then current status of considering ecoenvironmental water demand in planning and related planning is presented in details. Based on that the importance and urgence of introducing eco-environmental water demand in eco-environmental construction planning are as follows.(1) Collocating enough eco-environmental water demand is the key to eco-environmental construction planning;(2)introducing eco-environmental water demand presents new ideas and measures for water resource management, which promotes planning;(3) sound eco-environmental water demand is the subject of eco-environmental construction planning;(4) the objects of planning, on the contrary, improve the research of eco-environmental water demand.

接着对现在的生态环境需水在生态环境建设规划及相关规划中的应用情况作了详细介绍，在前面的基础上提出在生态环境建设规划中引人生态环境需水的重要性和紧迫性：(1)配置足够的生态环境需水是生态环境建设顺利进行的关键所在；(2)引入生态环境需水为水资源管理提供新思想、新途径，促进生态环境建设规划的实施；(3)合理的生态环境需水是生态环境建设规划的实现目标；(4)生态环境建设设定目标反过来又促进生态环境需水的研究。
