And so, to the front of the grid of challengers roared Mr Montezemolo. In his last big speech as president of Confindustria, the Italian employers' association, the elegant and telegenic Mr Montezemolo appeared to call on Italians to ditch Mr Prodi's shaky old two-wheeler and hitch their fortunes to a Formula One thoroughbred. In what Corriere della Sera on May 25th called a "transparent manifesto", he outlined a vision of what Italy could be by 2015 if it accepted the liberal reforms he proposed: a meritocracy with a flexible labour market and a sustainable welfare system; a country run by a more efficient, but smaller, government; a nation in which everyone paid taxes, but at a lower rate than now.

因此，前面很多挑战者都对 Montezemolo 不满，在他上次作为意大利企业联合会 Confindustria 主席时大型的演讲中，优雅上镜的 Montezemolo 看起来要号召意大利人废弃 Prodi 的两个摇晃的轮子，靠向一流的 F1方程式赛。5月25日， Corriere della Sera 说的一个叫"透明的宣言"，他强调一个意大利可能到2015年如果接受文化改制他提议的：一个灵活的劳动力市场和能维持的福利系统的精英体制；国家更有效的运作，但更小，政府；每人纳税的国家，但比现在低的。

These two qualities, the daunting and the fascinating, combine in a strange harmony of contrasts, and the resultant dual character of the numinous consciousness, to which the entire religious development bears witness, at any rate from the level of the 'daemonic dread' onwards, is at once the strangest and most noteworthy phenomenon in the whole history of religion.

帕斯卡认为世界上有两种智慧：一是那种简单无知的大众，他们生活在传统与想象的智慧中，以似乎是盲目，毫无抵抗的方式彻底掘弃自己地相信一种信念，然后通过约定俗成的礼仪与传古的神话来巩固自己的信念；另一种是圣人与哲人，这是一种通过科学，理性与哲学的探讨来认识自己的无知。

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.
