Then the sustainable development of Qitai artificial oasis was discussed. Researches showed that the oasis development has gone through three phases: The first was harmonic stage before the middle of 20, the oasis developed according to water resources. The second was unharmonic stage from 1950's to 1980's because of unreasonable policies, that is cultivated area enlarged rapidly and water resources exploited backward. As a result, land output was lower, and environment destroyed heavily. The third stage is after 1980's, the new fragile balance between oasis and its environment was established on the base of the more and more ground water utilization.

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.

In the top of the fifth, Posada helped Wang do just that. Rodriguez lined a single into the gap in left-center and reached second when Joey Gathright misplayed it. After Hideki Matsui walked, Posada - batting righthanded against lefthanded reliever John Bale - lifted a long fly to rightfield on which Teahen turned the wrong way. Possibly affected by the wind, the ball wound up hitting the base of the wall for a two-run double that gave the Yankees a 5-3 lead. www.wangfans.com; h2 E# 7 \/ f* i
