Secondly, the relevance feedback approach requires relevant documents to be similar to each other. That is, they should cluster. Ideally, the term distribution in all relevant documents will be similar to that in the documents marked by the users, while the term distribution in all nonrelevant documents will be different from those in relevant documents. Things will work well if all relevant documents are tightly clustered around a single prototype, or, at least, if there are different prototypes, if the relevant documents have significant vocabulary overlap, while similarities between relevant and nonrelevant documents are small.

第二，相关反馈方法需要相关文档之间相似，即它们可以聚类，理想地，所有相关文档 term 分布应该相似，相关档即用户标记的文档，同时不相关文档应该与相关文档的 term 分布不同，如果所有的相关文档都很紧凑地聚在一个单一的中心点，或至少有不同的中心点，如果相关文档有明显的词汇重复，同时相关与不相关文档相似性比较小，它才是可行的。

Aimed at the shortcomings of previous studies, this research constructs the system of primary school students' mathematics learning strategies, in which the using status, developmental traits and main influencing factors are investigated thoroughly. The processing mechanism of strategies is revealed both in psychological and physiological aspects through cognitive psychology and cognitive neuroscience methods. In order to promote children's strategy learning, the teaching method and effect are explored through the instructional experiment.

In this thesis, I summarize the theoretical calculation method, applied scope and notice of siphonic drainage system, and point out the advantage of siphonic drainage system compared with gravitation drainage system. In the archetype experiment study of siphonic drainage tube, I adopt different tube diameter and different structural height to survey the drainage volume and press in different place. I observe various kinds of flow state, and get chief factors which influence hydraulic peculiarity of system as the tube diameter or structural height, and find out the relevance of factor to flux. I apply CFD Fluent software and adopt standard k-ε model and RNG k-ε model, then use finite volume method and second-order upwind scheme to discrete numerical model, while coupling numeration of velocity field and press is based on SIMPLE. In the numerical simulation of curved part of tube, siphonic drainage tube experiment system and multi-outlet siphonic drainage system, I make research on internal velocity and press of system in different project condition by changing the tube diameter of curved part, negative press value in tube export and improving the quantity of water gutter. This thesis first adopts a method of combining archetype experiment and numerical simulation to study the siphonic drainage system, test and verify the validity of experiment and numerical simulation, and makefurther study on system, it solves the problems of limited testing conditions, and has a logical results, it can provide a valid method for optimizing and designing the drainage tube-net system. The conclusion have referring value for study and design of siphonic drainage system.

Objective To investigate the curative effect of left ventricular hypertrophy with uretic indapamide, Methods 96 patients wiht LVH were divided into two groups, 50 patients in A group were treated with indapamide 2,5～5mg/d, and 46 patients in B group with nifedipine 20～60mg/d for 12 months, Results Blood pressure、interventricular septum thickness、left ventricular posterior wall thickness、left ventricular mass index and left ventricular ejection fraction in all cases were improved after treatment, A group was better than B in LVEF, Conclusion Both indapamide and nifedipine can regress LVH, and improve left heart function

目的 观察新型噻嗪类利尿剂吲达帕胺逆转左心室肥厚的效果。方法 96例高血压LVH患者，分别给予吲达帕胺(A组，50例)2，5～5mg/d和硝苯地平控释片(B 组，46例)20～60mg/d持续12个月治疗，观察治疗前后血压及左室结构变化。结果两组治疗前后血压、室间隔厚度、左心室后壁厚度、心室重量指数和左心室射血分数均有改善(P＜0，05～0，01)，A组在改善LVEF方面优于B组(P＜0，05)。结论吲达帕胺具有与硝苯地平类似的逆转LVH作用，有明显改善左心功能作用。

Much work has been done on multi-objective optimization methods to make them turn from deterministic searching algorithm to stochastic searching one, and from single objective optimizing method in nature to veritably vector optimization method. At present there are still many unsolved problems on it.

摘 要 多目标优化方法经历了一个从确定性搜索算法到随机搜索算法的过程，本质上仍是单目标优化的目标组合方法到真正意义上的向量优化方法的过程，至今仍在不断地发展中，但仍有大量未解决的问题。
