欧洲央行的主要关注点应该在防止在一家银行违约的情况下，其它作为成员的央行面临亏损的风险，还要保证各家银行没有以优惠的形式将自己的信贷风险转嫁到欧洲央行身上。

This paper studies the concept and key facts of the enterprises' autonomous technological innovation, then it constructs a model of the key factors' conduction mechanism according to the logic of the SCP structure, finally it analyses the innovation path of china's enterprises and suggests that under the resources constraint, the feasible solution of china's enterprises is congregating resources to capture the subdivide market, then taking this as the chance, realizing the transformation from partial breakthroughs to overall rising by technology accumulation.

本文在现有研究的基础上，研究了自主技术创新的概念及其关键因素，然后按照战略－行为－绩效的逻辑关系，构造了关键因素间的传导机制模型，对我国企业自主创新的路径进行分析，认为在资源约束下，我国企业的可行途径应是通过资源集聚，占领细分市场，保证技术和市场的良性互动，然后以此为契机，通过技术积累实现由局部突破向全面崛起转化。

In this article two functional modes of the Fly-back Converter (Continuous Conduct Mode and Discontinuous Conduct Mode) are particularly analyzed, which include their characteristics, applications, the critical pattern of two functional modes is argued, both the exact boundary from the angle of circuit parameters is crystallized, at the same time, basic principle of PFC under the DCM mode is introduced, which settle theoretical basis for the subsequent design; by establishing the mathematic model of the converter, a further investigation of the configuration is made, qualitatively and quantitatively, analyzed to settle exactly theoretical basis for the subsequent emulation and the experimental parameter; from the angle of steady-state analysis, the transfer function of the system is deduced to establish dynamic small-signal state equation, emulating the system with the help of matlab, then according to the simulation result and the theory of PFC revise the system, lastly, we adopt the project which add a zero-pole compensator to the voltage loop, by this way, a satisfied system performance is gained and the PFC scheme is ensured successfully; finally, based on the previously-done work, we combining with the situation of specific design requirement, acquired the numerical value of each unit devices in this converter

详细分析了反激式变换器的两种工作状态，连续模式(Continuous Conduct Mode ，简称CCM)和断续模式(Discontinuous Conduct Mode，简称DCM)以及各自的特点、应用场合，论证了两种工作状态的临界模式，从电路参数的角度明确了二者的界限，同时还介绍了DCM模式下PFC的基本原理，为后面的设计奠定理论基础；通过对整个变换器系统建立准确的数学模型，对此变换器的电路结构做了进一步的研究，定性、定量地分析了变换器各部分的工作状态，为仿真和实验参数的确定以及电路参数的优化提供理论依据；从稳态分析的角度，为系统建立了动态小信号状态方程并推导出系统的传递函数，利用matlab对系统进行仿真，进而根据仿真结果以及PFC的相关理论对系统进行校正，采用在电压环加入零点—极点补偿器的设计方案，得到了满意的系统特性并且保证了PFC的顺利实现；最后，在前面所做工作的基础上，结合设计要求计算出此变换器系统中每个元器件的数值，利用Pspice对其进行了仿真、优化，然后根据仿真结果搭建了硬件电路。

On the design of index system, this paper introduces the idea of BSC to design the frame of index system, to explain the index system from the four dimensions of finance, custom, management, and development. The basal indexes of each dimension is filtered in the way of partial correlate of these indexes and EVA form the point of view of validity andindependence, and gets well indexes to make up the index system of Advanced Professional Executives performance evaluation.

Underwater color photography was born with this shot of a hogfish, photographed off the Florida Keys in the Gulf of Mexico by Dr. William Longley and National Geographic staff photographer Charles Martin in 1926. Equipped with cameras encased in waterproof housing and pounds of highly explosive magnesium flash powder for underwater illumination, the pair pioneered underwater photography.
