At the moment, however, I want to focus on perception and make three points. The first is a point about the intimacy of the connection between perception and action. It involves an argument designed to show that, contrary to what we might suppose, there is no logical or conceptual gap between our conscious perceptual awareness and our corresponding agential capacities. Needless to say, the argument is designed to make the agential approach to direct perception less unintuitive. The second point is made with the same aim, but proceeds from the opposite side. That is, I argue briefly for the inadequacy of the sense-datum conception of visual perception (the source of virtually everyone's "pre-theoretical" intuitions, regardless of their theoretical commitments). And I do so on phenomenological grounds.

此刻，无论如何，我需要集中在感知上，指出三点。1、关于感知和行为之间的密切关联，这包含一个被设计的论证，以指明在'我们有意识地感知'和'我们有意识地agential能力'之间不存在逻辑或概念上地gap，而无需说，这个被设计的'直接感知的agential进路'的论证更少非直观。2、同样的目的，但起点反过来，即，我简单论证了视觉感知的感觉材料概念的不充足（事实上每个人的前理论直观的源头，无论有何种理论承诺），我做这个基于现象学基础。

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.
