So in order to deal with the problem, both the living habit and distribution of Chironomus larva in the water treatment system and the methods in removing Chironomus larva at present were introduced in this article. Meanwhile, the relationship between its physiological characteristic and environmental factors was demonstrated. Also the research status、advantage and limitation of different methods in the remove of Chironomus larva were analyzed systematically and some scientific tendencies were prospected. It was suggested that enhancing the management to the raw water and optimizing the drinking water treatment processes were the feasible ways to effectively control the pollution.

本文首先介绍了摇蚊幼虫的生活习性及其在水处理工艺中的分布规律，然后对其生理特性与环境因子之间的关系进行了论述；并就近年来采用物理法、化学法和生物法防治水处理工艺中摇蚊幼虫污染的研究进展、现状和局限性进行了较为系统的分析，展望了摇蚊幼虫污染防治技术的研究前景，指出目前控制饮用水中摇蚊幼虫污染必须将水源水质水控制、污染治理与净水工艺处理结合起来，优化水处理工艺和强化水源水体保护是根本保障。

In the citrus orchards in Canton suburbs the pradaceous mites, chrysops, mite-eating ladybird, certain species of thrips and spiders have been found to be the natural enemies of the citrus red mite Panonychus citri McG.

经过两年的试验证明，以利用钝绥螨为主，少量使用选择性农药和加强田间管理的综合措施，是防治柑桔红蜘蛛行之有效的途径，可长期控制其数量在防治指标以下，化学农药的用量也相应大大减少。

Vascular hyperpermeability is one of the important causein hypovole-mia and organs disfunction after various kinds of shock,and its treatment is still one of the problems in the medical field. For example,the operative methods of preventing hyperpermeability and plasm bleeding is still unreliable after severity burn,and traditional treatment just passively transfuses according to the burn clysis formula instead of inhibiting permeability by injecting drugs. The principal reason is that pathogenesis of vascular endothelial cell permeabilty has not been entirely revealed at the level of molecular biology.

血管通透性增高是休克时有效血容量减少和器官功能损害的重要原因之一，它的防治一直是医学界的一个难题，如在大面积烧伤时，至今未能找到一个简单有效的防治血管通透性升高和血浆渗出丢失的方法，传统的方法只是根据烧伤补液公式测算进行被动的补液来纠正，而不能依靠注射化学制剂来终止其渗出，主要原因是未能从分子生物学水平揭示血管内皮细胞渗出的机制。

The incidence of Sitodiplosis mosellana has following four factors, which are a new insect in Beijing area, concealable behavior, rapid growth of population and poor understanding of the insect.

通过对小麦吸浆虫发生为害调查、防治试验和灾害控制，明确了该虫在北京市成灾的主要原因有4点，即吸浆虫是外来入侵的新害虫，生活、为害隐蔽，种群数量增长迅速和防治不及时。

To provide a non-toxic, zero-residue and effective approach to prevent the parasitical Ascaris suum, the effect of kaempferol-3-a-L-(4-O-acetyl)-rhamnose-7-a-L-rhamnoside,extracted from Cyrtomium yunnanense, on the the animals infected with A. suum was studied.

为猪蛔虫病的防治提供无毒、无残留，对人体无害的高效防治方法，利用云南贯众分离得到的化合物山奈酚－3-a-L-（4-O-乙酰基）鼠李糖基－7-a-L-鼠李糖苷作为试验用药，对感染猪蛔虫的动物进行了药效试验研究。

The preventing and controlling best time in the nymphae time,Dactylopius confusus\'s nymphae time in the end of February and at the beginning of March,is generally good in this time preventing and controlling effect,simultaneously must pay attention to each medicament to gather the theory with and mixes uses,delays its antibiotic production.

防治的最佳时期一般在若虫期，胭(来源：5cABC论文网www.abclunwen.com)脂虫的若虫期在2月底3月初，在此时期防治效果较好，同时要注意各种药剂的合理轮用及混用，以延缓其抗药性的产生。来源：A0424B42C论文网www.abclunwen.com

Third, evaluate the risk of the disaster the debris flow brought. Confirm evaluation area on danger area basis, then evaluate the fatalness, damageability, loss of the debris flow. Finally, combining with foregoing research, put forward an economical and effective preventing and curing scheme for the debris flow happened in Qiongshan ditch, moreover, evaluate the projects benefit.

然后对此沟泥石流所造成的灾害进行风险评估—根据泥石流的危险范围确定评估范围，再进行危险性评价、易损性评价和灾害破坏损失评价；最后结合前面的研究，对邛山沟泥石流提出经济合理的防治方案，并对其进行防治工程效益评价。

Plant Virology 2 S T. H. Chen, FThe course will give conventional and molecular level of plant viruses in order to help the students to get much theoretical and practical knowledge about plant virology. The contents cover the molecular structure of virion and genome, virus isolation, dentification and purification, transmission, variation,ecology, nomenclature and classification, diagnosis and control.

本课程除传统植物病毒学范畴外，并涵盖从分子层次讨论植物病毒之构造，引起之植物病害，田间发生及防治，期能达到理论与实务并重；内容包括植物病毒分子层次的构造及核酸组成，病毒分离、鉴定与纯化，在寄主体内之增殖及转移，媒介传播、遗传及变异，其引起之病害及田间发生生态与防治。

All kind of structure changes do not occur at the same time, for example the epithelial desquamation occurring after exposure for 1 week and sub- epithelial fibrosis occurring after exposure for 8 weeks, and it is incomplete that the prevention of inhaled corticosteroids on airway remodeling. So inhaled corticosteroids should be introduced to treat asthma as early as it possible.

5哮喘气道重塑过程中，气道结构的各种改变是不同步的，气道上皮脱落在激发1w后即可发生，而上皮下纤维化在激发sw后出现，且ICS对气道结构改变的防治是不完全的，故临床上应及早使用ICS治疗，并结合其他抗炎剂如白三烯受体拮抗剂以最大程度地防治气道重塑的发生。
