This doctoral dissertation is composed of several parts: At beginning, the frontal structure, the effects of diabatic heating and orography, the dynamics of frontal circulation and the mesoscale systems associated with front are reviewed. Several problems based on the review are brought forward. First, at present, the semigeostrophic frontogenesis theory is the most appropriate basic framework for the general explanation of the frontogenetic process. However, the comparison between semigeostrophic theory and the observation have revealed some inconsistencies. The newly observational facts increase the inconsistencies.

本博士论文主要由如下几部分组成，首先对锋面结构、地形和非绝热加热对锋的影响、锋生环流及锋面附近中尺度系统动力学问题的历史与现状进行了综述，在此基础上提出需要进行研究的若干问题：(1)、半地转锋生理论直到今天仍是解释锋生过程的最合适的理论框架，但是通过与观测事实比较，人们发现半地转理论不能对许多锋面观测特征给出令人满意的回答，新的观测事实使问题更加突出，这就向人们提出：是什么原因导致半地转理论与实际观测的不符？

计算表明，多向地震动下的面板峰值小主应力、顺河向峰值加速度及坝体的永久变形均与单向和双向输入时显著不同，实际工程计算时应同时考虑三个方向的地震动；振动型地震激励引起的坝体反应明显大于冲击型地震激励；随着地震动强度的增加，峰值加速度、峰值剪应变、面板应力和周边缝变形等增加；面板刚度对面板的应力值和周边缝的变位具有较大影响，当面板模量取值较低时，计算所得到的"面板"应力集中部位不甚明显，计算结论为新型的"土工膜面板堆石坝"提供了理论依据。

With the support of a major research grant of Zhejiang Province (No. 001101027) and the Plan of Promoting Education of Excellence of Zhejiang University in the 21st Century, this dissertation is devoted to address the above problems and fabricate an L-band EDFA with low cost, high performance and technological innovation.First the mechanism of an erbium doped fiber amplifier is introduced. Various theoretical models based on classical rate propagation equations are summarized and compared for their applications. We use a modified numerical model based on the Giles model, which agrees with the experimental results well. This serves as the theoretical base for the whole thesis and will be used to optimize the characteristics of EDFAs. A novel method based on a map of noise figure and gain is proposed to analyze efficiently the dependence of the noise figure and gain for EDFAs on the EDF length and the pump power. The characteristics of various EDFAs are studied and compared.Secondly, some important parameters are introduced to describe the characteristics of EDFAs. The methods and the experimental setups for measuring the gain and noise figure of an EDFA are emphasized. We introduce how to measure the characteristics of each component of an EDFA, especially the gain and absorption coefficient of an erbium doped fiber.Thirdly, four types of simple and novel L-band EDFA structures with low noise, high gain and low gain ripple are proposed to satisfy the requirement of a DWDM system. They can be classified into two categories. In the first category, a single ASE pumping is served asa secondary pump. This category includes the following three types. Type: a new construction using a fiber Bragg grating in an unpumped EDF section at the input side. Type: a new structure of L-Band EDFA with two-stage pumps, which utilizes the forward ASE as a second pump.

The author mainly discusses the relationship between the two culture phenomena: culture identification and culture uniform tendency, describes the culture identification in the minds of people in the period of culture globalization, detailedly traces the historical evolvement of culture identification, and expatiates the theory of cultural nationalism 3identification, strong culture identification and entirely westernization identification, at last objectively gives some opinions on the realistic function of western culture in the development of modern society. Meanwhile, the author does not echo what other says, and entirely opposes the what is called culture imperialism or western culture intimidation, on the contrary, the author impersonally analyses some other voices which is arisen with deconstructionism, reminds people must start from national practice, recognize the predominance and shortcoming of one's own national culture, neither narcissism nor self-humiliation.
