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.

对枣粮间作系统和三种对照系统，即除草枣园系统、未除草枣园系统和农田系统的节肢动物群落进行对比分析发现枣粮间作系统具有更为丰富的中性节肢动物类群，比起除草枣园系统和农田系统有更优势的天敌类群和更劣势的植食性类群，且在遭受生境的巨大变化后新生境重新形成时枣粮间作系统的各亚系统能更迅速的形成节肢动物群落和各种功能类群，说明枣粮间作系统比三种对照系统的节肢动物群落有着更合理的结构、更强的调控能力和更强的控害能力。

This paper includes several parts: first, some important concepts of the thesis have been defined, a theoretical overview of currency crisis has been finished; then, we have described the history of the international monetary system; later, three chapes have been arranged to discuss the mechanism of currency crisis under fixed and floating and intermediate exchange rate system respectively. The part of the fixed exchange rate system mainly includes the analysis of the collapse of the international gold standard system, the Bretton Woods system and the the European Monetary System; in the part of the floating exchange rate system, the volatility problem under freely floating exchange rate system has been studied; the part of the intermediate exchange rate system mainly includes the analysis of currency crises in regional dollar standard system and the currency board system. And finally, we have analysed the inevitability of the appearance of new type regional monetary cooperation patterns, and how these cooperations avoid currency crises.

本文主要包括这样几部分：首先，对论文中涉及到的重要概念给予界定，并对货币危机理论进行系统梳理；接着，按时间顺序从总体上回忆国际货币制度的历史演进；然后，用三个章节分别研究了固定汇率制度、浮动汇率制度以及中间汇率制度下货币危机的形成机理，其中，固定汇率制度下的货币危机主要包括国际金本位制度和布雷顿森林体系的崩溃，以及欧洲货币体系的瓦解；浮动汇率制度下的货币危机，则重点分析了自由浮动汇率制度下汇率的过度波动问题；中间汇率制度下的货币危机，分别分析了区域美元本位及货币局制度下货币危机的发生机理；最后，分析了目前新型区域货币合作模式出现的必然性，及各模式下如何规避货币危机。

The following exciting results are revealed: 1 When considering the influence of some nonlinear elements such as hard-limit of exciters, the effects of some devices such as Power System Stabilizer and Static Var Compensator which can introduce positive damping in power system, the reasonability of system parameter values in simulation, the SNB surface and HB surface on the boundary of SSSR will turn close to each other and even coalesce together; 2 Under some conditions, coupling between slow exciters and shunt capacitors will bring negative damping in power system dynamics, which increases the possibility of oscillatory instability. So the power system with mass shunt compensators is easily subjected to the oscillatory instability. In recent years, chaotic phenomena of power system have been reported many times. Some simulation studies even found chaos existing inside the power system SSSR. In this dissertation, chaotic phenomena in power systems are thoroughly studied in order to make clear the relation of chaos and SSSR. The following results are derived: 1 Based on Li-Yorke Theorem and their definition on the chaos, the existence of chaos in power system is verified; 2 Three possible routes of causing chaos in power system are found and deeply investigated. They are route of cascading period doubling, route of directly initial energizing and route of torus bifurcation (or quasi-periodicity). The latter two routes are investigated for the first time in power system stability studies; 3 When the stability conditions of chaos are broken, it is found they can lead to voltage collapse, angle divergence, or voltage collapse with angle divergence simultaneously.

针对在电力系统小扰动稳定区域内可能存在混沌吸引域的有关报道，本文深入研究了电力系统混沌现象的出现途径和与系统失稳模式之间的关系：1利用Li-Yorke定理和Li-Yorke的混沌定义，从理论上证明了电力系统混沌现象的存在性；2发现了电力系统中导致混沌出现的三种可能途径：倍周期分岔导致混沌、初始能量直接激发混沌和经由环面分岔导致混沌，并对后两种新发现的途径进行了较为细致的研究；3发现了混沌极限环破裂导致电压崩溃、角度失稳以及电压崩溃和角度失稳同时出现的现象，其中混沌极限环破裂导致系统角度失稳和电压崩溃及角度失稳同时出现的现象均属首次报道；4证明由微分-代数方程描述的系统模型，其小扰动稳定域的边界只包含HB、SNB和SIB三种分岔界面，在SSSR的内部和边界上，均不可能存在会导致混沌的点，从而将混沌现象排除在小扰动稳定域的研究之外，简化了后者的研究工作。

Factory remaining hot water, remaining vapor and boiler heating system, were adopted in tilapia overwintering. Every step, such as site selection, pond and fish preparation, cultivation of fish, fish selection, timing of overwintering, stocking density and managements during overwintering, was compared among three systems. The results of data analysis showed that the survival rate in remaining hot water system was 12% higher than in remaining vapor system and 21.25% higher than in boiler heating system. The overwintering cost in remaining hot water system was 735 Yuan/m~3, which was 18 Yuan lower than in remaining vapor system and 71.4 Yuan lower than in boiler heating system. The profit in remaining hot water system was 201 Yuan/m~3, which was 162 Yuan higher than in remaining vapor system and 275.4 Yuan higher than in boiler heating system.
