The personal income tax exemption volume law system as its tax revenue reduces the system, day by day also has become an important system relating to national economy and the people"s livelihood, but this system continuously has rarely had the change since 1994, but inhabitant"s income level unceasingly enhances, the price also unceasingly rises, in recent years our country promotes the housing system, the medical system, the social security system, the educational system and so on many reform measure, obviously, at present our country personal income tax exemption volume legal system and the development of economy and society are in disconformity, the function of adjusting income assignment gradually weakens, the unfair tax burden question extrudes day after day, The perfection of our country personal income tax exemption volume law system call is more and more high, the experts and the scholars also pays more and more attention to the research of this system.

个人所得税免征额法律制度作为一项税收减免制度，也日益成为了税法当中一项关乎国计民生的重要制度，但该制度自1994年以来一直鲜有变化，而居民的收入水平不断提高，物价也不断上涨，近几年来我国又推出住房制度、医疗制度、社会保障制度、教育制度等多项改革措施，显然，目前我国个人所得税免征额法律制度与经济社会的发展情况已不相适应，调节收入分配的职能逐渐削弱，税负不公的问题日渐突出，完善我国个人所得税免征额法律制度的呼声越来越高，专家和学者也越来越关注该制度的研究。

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.

Through the comparative analysis of the arthropod community between intercropping system and the three control systems～the weeding jujube yard system, not weeding jujube yard system and the system of farmland, it is showed that the intercropping system have a more richer neutral arthropod groups. Compared to Weeding jujube yard system and system of farmland the intercropping system have more advantages in natural enemies groups and more disadvantaged phytophagy groups. And the intercropping system can rebuild the arthropod community more faster than the other systems after the system was seriously disturbed, so it is than compared to other three systems the intercropping system have more proper structure and more stronger regulation ability and also more stronger ability to control pest.
