From the industry to observe,the author discovers that the regional gap of the secondary industry was the primary contributor,but the rate of was descending.The third industry was becoming the important contributor.The industry structure adjusting and the agglomeration of the third industry and the secondary industry are the primary reason of the forming of the disparity of between the east and the rest areas.In the 1978 to 2005,the absolute convergence of economic growth didn't occur,the other way round,the club convergence of economic growth occurred in the east and in the middle.The speed of the economic growth in the east was higher about 1 centigrade than the middle and the developing west,and was higher about 2 centigrade than the west.

从以省区为单元的中国地区经济发展差距形成的产业构成来看，第二产业的地区差距长期以来都是中国地区经济发展差距的主要贡献者，居主导地位：但是随着第三产业产值比重的提高和第三产业地理集聚的非均衡性扩大(1990年以后)，第三产业的地区差距正逐渐演变为以省区为单元的中国地区经济发展差距形成的主要贡献者。1978-2005年期间，中国地区经济增长并没有出现绝对收敛趋势，而是表现为东中部地区内部的"俱乐部"收敛。1978-2005年东部地区经济增长速度比中西部地区更快，东部地区平均经济增长速度比中部地区高1个百分点左右，比西部地区高接近2个百分点，地区间经济增长速度存在显著的差异。

The method of the research in the paper is impellent,and the basal research course is the following.Firstly,the author uses the Theil coefficient and Gini coefficient to analyze the regional economic gap,and decomposes the structure in China.At the same time,the author tests theσconvergence,the absoluteβconvergence,the conditionalβconvergence and the club convergence.Secondly, the author analyzes the forming reason and mechanism of the regional economic gap in China.

本文研究过程中采取逐步深入的推进方法，其基本研究思路是：首先，使用基尼系数和泰勒指数对中国地区经济发展差距的历史演变轨迹进行了分析，并对其形成结构进行了分解，同时对中国经济增长的σ收敛、绝对β收敛、条件β收敛和"俱乐部"收敛进行了检验，以此为基础形成了对中国地区经济发展差距的全面了解；其次，以新古典增长理论和新增长理论为基础对中国地区经济发展差距的形成机制进行了分析；再次，以FDI非均衡分布为视角对中国地区经济发展差距的形成机制进行了解释；最后，提出了本文的政策建议。

In addition,Various methods of stability analysis of wakes behind bluff bodies arediscussed,among which the general theory of absolute/convective instability is strictlyformulized from stability equations of viscous flow;the theoretical foundation of stabil-ity analysis of time-average flows is also discussed from basic equations of fluids,andthe reason for the stability analysis of time-average flow can predict the frequency inthe saturation state is explaned.

此外，讨论了钝体尾迹稳定性分析的各种方法，其中从粘性流的稳定性方程出发严格推导了绝对/对流不稳定性的理论公式；从基本方程出发探讨了采用时均流场作稳定性分析的可行性，并解释了用时均流场作稳定性分析可以更好地预示饱和频率的原因。

In the second chapter, we investigate propagations of desynchronous disturbances in synchronized chaotic one-way coupled map lattices. It is well known that spatiotemporally chaotic systems with large gradient couplings may show convective instability under the absolute stability condition of chaos synchronization. This convective instability is the key reason for the effective propagation of control signals.

时空混沌在不同的耦合系数情况下会表现出不同的动力学行为，用驱动实现具有强梯度耦合系数的时空混沌同步时，会观察到在绝对稳定条件下被驱动系统表现出对流不稳定性，这种对流不稳定性是在单个信号驱动下实现混沌同步的关键原因。

在中国共产党的文献中第一次把发展慈善事业提到&最广泛最充分地调动一切积极因素，不断提高构建社会主义和谐社会的能力&的高度来认识。近年来，社会学界对慈善事业的理论专著发表较多，有鉴于此，笔者不揣浅陋，谈谈自己的认识和见解。
