In this paper , an analysis is made on the data generation procession of money supply and price in china , using the theory of structural change and cusumsq test 摘要运用结构突变理论和cusumsq对我国货币供应量与物价的数据生成过程进行经验分析表明，我国货币供应量和物价分别服从单位根过程和结构突变的趋势稳定过程，且表现出较强的“路径依赖”特征。
Based on the theory of structural breaks , we studied on the different structural breaks models in dgp , and proposed its test methods , which can distinguish unit root with structural breaks from trend stabilization with structural breaks 本文基于结构突变理论，研究了数据生成过程中的几种不同结构突变模式，并对结构突变的单位根过程和结构突变的趋势稳定过程给出了不同结构突变模式的检验方法。
What is more , for china ’ s stock market has not only the character of new market , but also the particularity caused by institutional change , analyzing structural change is significant to comprehend and master the stock market fluctuation features 此外,我国股票市场不仅具有新兴市场的特征,而且表现出特殊性,对股票指数序列进行结构突变搜索与分析,为深入理解股票市场的波动过程提供了重要的信息。
The most significant declines , which are traced back to roughly 90 , 000 years ago , 45 , 000 years ago , and 10 , 000 years ago each involved major nuclear catastrophes , which mutated the human genetic structure to such a degree that a major drop in vibration occurred over the course of one generation 最重大的下降，概略地追溯至90 , 000以前、 45 , 000年以前和10 , 000年以前，每个时期都包括了重大的核灾难，使人类基因结构突变入如此程度，让一代人的振动发生较大下降。
The paper combined the stock index with the study on structure change . on one side it is because the stock index apparently has the characteristics of structure change and is representative of it ; on the other side , there are many confusing phenomenon arising in chinese stock market such as going opposite to gdp growth rate while growing in pace with net exports and currency supply 本文结合上证指数对结构突变进行研究，一方面是因为上证指数在形式上具有明显的结构突变特征，具有代表性；另一方面，中国股市呈现出了许多令人迷惑的现象，一方面，如与gdp增长率相背离，却与净出口、货币供应量等具有同步的特征。
After studying a lot of literature on issues related to structural change , this dissertation introduces group method of data handling ( gmdh ) , modeling gmdh auto - searching structural change , to avoid the possibility that the traditional endogenous methods maybe falsely decide the most outstanding break - point 本文在分析了结构突变理论及其研究现状以后,引入gmdh ( groupmethodofdatahandling ) ,建立了gmdh自动搜索结构突变模型,避免了传统单结构突变方法可能有偏地决定最显著结构突变点的局限性。
As long as f statistical value constructed by sectional regression exceeds the given critical value , structural change happens . the critical value is exactly the structural change point and the study on this point just constitutes the structural change problem . the further study on this problem is accompanied by the development of the unit root and cointegration theory Chow提出，只要由分段回归而构造的f统计量超过了给定的临界值，就认为发生了结构变化，而发生结构变化的临界点就是结构突变点，对结构突变点的研究就构成了结构突变问题，结构突变问题随着单位根和协整理论的发展而被得到深入研究。
The modeling method can solve not only the problem of the number and the location of breaks which the multiple structural changes theory requires , but also take the break kinds of every structural change into consideration , which is likely to be of particular relevance in practice 这种建模方法,不仅能够解决多结构突变理论要求解决的结构突变个数和结构突变点的定位问题,而且能够同时考虑每个结构突变点的突变类型,从全局出发考虑多个突变点,搜索出显著的多个结构突变点,符合实际情况。
This paper has made no further breakthrough on structure change model , the prominent specialty of this paper lies in the new points of view on the internal mechanism of structural changes and the new definitions of both the structural changes and the related problems . the thoughts of the author embodied best is the judgment that the structural changes are caused by external factors and the internal factors will never result in structural changes 本文对于结构突变模型尚没有更深的突破，但本文最大的特色是对结构突变的内在机理提出了一些新的看法，并重新对结构突变及相关问题加以了新的定义，笔者的思想集中体现在提出了“结构突变由外生因素引起，内生因素不会引起结构突变”的判断上。
5 . the mechanism of unscented kalman filter ( ukf ) is analyzed and a new multiple model estimator based on ukf and imm is proposed for maneuver target tracking with non - linear measurements . simulation results show the superiority of this new algorithm in dealing with such systems 提出了一种基于unscentedkalmalfilter ( ukf )的交互式多模型算法，该算法结合了imm算法对系统结构突变的跟踪能力和ukf算法对系统状态或量测方程非线性的处理能力，并在二维非线性机动目标跟踪中显示了其比基于ekf的imm算法的优越性。
