The results showed that: the influence of the aquaculture process on aquaculture water determined by type of aquaculture; the influence of aquaculture process on the water temperature, salinity and pH value were not wide.the descent of pH value was related to feed coefficients ; the dissolve oxygen of water in outfall was lower than the water in infall,but the concentration still maintained at the saturation level, is mainly affected by density of aquaculture ,rate of feed and artificial measures of increasing oxygen ;the major form of inorganic nitrogen was nitrate-N;the concentration of inorganic nitrogen and the organic matter tended to increase ,but the ammonium to decline ,this was relation with density of aquaculture ,rate of feed and variation of the different inorganic nitrogen form ; concentration of phosphate-P was low in outfall of pond , related with phosphate-P precipitating, as flowing water speed slowly in outfall;This phenomenon that the total number of bacteria and coli form group of water in outfall was lower than the water in infall , this caused by measures of sterilization and disinfection .

结果表明：养殖过程对水体影响与养殖类型有关。养殖过程对水体的水温、盐度和pH影响不大； pH下降与饲料系数高有关；溶解氧含量排水口比进水口低，但仍维持在饱和状态，与养殖密度、投饵率和人工增氧有关。硝酸氮是无机氮的主要存在形式，无机氮和有机物含量有升高趋势，氨氮有下降的趋势，与养殖密度，投饵率和各种无机氮之间的相互转换有关。活性磷酸盐含量在排水口含量下降，与排水口流水速度慢，磷酸盐沉淀有关。生物指标细菌总数和大肠杆菌总数在排水口比进水口低现象普遍存在，这与养殖场杀菌消毒等措施有关。

农村已婚育龄妇女性传播疾病病原体感染率较高，这与文化程度低、卫生保健知识知晓率低、不良的卫生行为有关。

In chapter two, concepts of integrity, integral set and integral number are introduced firstly, and then some relationships between the integrity and some other parameters of graphs are given, then the upper and lower bounds of the integrity are investigated on the basis of integral number determined. The final result is the upper and lower bounds of integral number if the integrity is known.

第二部分主要讨论了完整度与图的其它参数之间的关系；给出了完整度给定条件下完整数的最大可能值及完整数给定条件下，完整度的最大最小可能值；给出了图的完整度与此图的删点子图的完整度之间的关系。

This thesis consists of five chapters. At first, We introduce the study history as well as present situation on KKM theory. Secondly, We discuss the invariability of transfer open valued multimap under the restriction of upper and lower semicontinuity on generalized convex spaces. Then, We obtain new KKM type theorems from the classical KKM theorem by applying upper and lower semicontinuity. We also obtain intersection theorems by applying the KKM type theorems for a multimap from a topological space to another topological space. Further, We obtain Ky-Fan type coincidence theorem by applying known variational results on the KKM type theorems. Finally, We give an application to new theorems.

本文共分五章，首先回顾了KKM理论的研究历史和现状，其次讨论了在一般化凸空间上转移开值映射在上、下半连续映射下的不变性，然后在上、下半连续映射下，以古典的KKM定理为基础得到新的KKM型定理，并利用从一个拓扑空间到另一个拓扑空间的集值映射及KKM型定理得到相交定理，进一步利用已知的KKM型定理的变形结论得到Ky-Fan型重叠定理，最后给出新定理的一个应用。

PDA was often combined with all kinds of intracardial malformation ,preoperational diagnosis and interoperative exploration are extremely helpful for diagnosis . A strict control of indication and the improvement of CPB technique are significant to lower the death rate and postoperative complication . Suturing PDA through incision in pulmonary artery under CPB is the main treatment for PDA, using Foley catheter to block arterial canal flow helps to fully expose the operating field 、shorten CPB duration and lower the complications of lungs and brain .

各种心内畸形经常合并PDA，术前诊断及术中探查，意义重大；严格掌握手术指征和提高CPB技术，对降低手术死亡率及术后并发症具有重要意义；经肺动脉切口缝闭PDA是CPB下处理PDA的主要方法，术中应用 Foley导尿管阻断动脉导管血流，有利于术野显露、缩短CPB时间，可降低肺部、脑部并发症。
