A time always comes at which the moral principles originally adopted have been carried out to all their legitimate consequences, and then the system founded on them becomes as rigid, as unexpansive, and as liable to fall behind moral progress as the sternest code of rules avowedly legal.

The truth was, that the little Puritans, being of the most intolerant brood that ever lived, had a vague idea of something outlandish, unearthly, or at variance with ordinary fashions, in the mother child; therefore scorned them in their hearts, not unfrequently reviled them with their tongues.

But the effect of her being on those around her was incalculably diffusive: for the growing good of the world is partly dependent on unhistoric acts; and that things are not so ill with you and me as they might have been, is half owing to the number who lived faithfully a hidden life, and rest in unvisited tombs.

We of course can't deny the significance of transcendent asthetics and consumption asthetics. Because transcendent asthetics can give some critical proposal to the negative and had phenomenons in asthetic and art under market economic condition. Consumption asthetics possibly make some contribution to the research about connection between asthetic and consumption. But we should resolve a series of asthetic problem in the development of China socialism market economic realistically, historically and scientifically (expansively speaking, it's problem confronted by world contempory asthetics, including the connection between consumption and asthetic). We can't drop in some unrealistical and unhistorical fantasy, nor confused by temporary froth and illusion.We still need rely on the development of asthetics of Marxism practicing outlook nowadays.

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.

A new case-matching algorithm, namely ANNI, is proposed in this paper. It uses artificial neural network to setup the mapping relationship, which is generally decided by human expert before and full of unreasonability in weight setting. The ANNI algorithm is proven to be very suitable for mapping between complex-related factor sets and can be applied in case-matching calculation.
