For example:metaphor and cycle factors were never mentioned before;It is the important factor to analyse Chinese accient system reasonable core;the author emphasize that harmonious interhuman also is the important factors of reasonable core.Tochinese accient system ideas culture value,the passage proclaims the inner relationship between Chinese accient system idea and Chinese nation spirit and puts forward the point that Chinese accient system idea is the philosophy base of Chinese nation spirit,especially of partriotism sprit.if grasping this point,it undoubtly has reality meaning study and perform "three represents"essencial thought and reinforce nation sprit and partriotism education.
这些见解突出表现在,对中国古代系统观民族特色的概括有新的视角,如"隐喻性"、"圜道性"特色几乎未见有人提过;对中国古代系统观合理内核的分析,也摆脱了通常围绕自然系统观提法的框架,强调"人际和谐"人文系统观也是合理内核的重要因素,恰恰在这一点上,人们常常没有给以足够重视;对中国古代系统观的文化价值,作者有意没有给以全面展开,只是突出其中的几个方面加以简要分析,创新之处在于,揭示了中国古代系统观与中华民族精神之间的内在联系,提出中国古代系统观是中华民族精神特别是爱国主义精神的哲学思想底蕴这一观点,领悟和把握这一观点,对学习贯彻"三个代表"重要思想,加强民族精神特别是爱国主义精神教育无疑更具现实意义。

So, the nucleocytoplasmic ratio decreased. 10^(-5)MATRA significantly suppressed the proliferation of os732 with only 39.5% cells when compared with untreated cells. Cells in G1 phase increased significantly, and the number of S phase decreased. Expressions of cy-clinD1, cycimD2 and CDK4 mRNA declined, especially cyclinD2 and CDK However, expressions of cyclinD3 and P21WAF1 mRNA changed little.

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.
本论文本着科技创新、服务于生产实践的精神,以设计价格低廉,性能优越、结构合理简单的L-band EDFA为目标,依托浙江省科技厅重大科学基金资助项目(001101027)和浙江大学振兴教育计划资助的全光网络的搭建—《光通信技术》课程实验建设项目,展开了如下工作:首先,介绍了掺铒光纤放大器的工作原理,归纳总结了基于速率方程基础的EDFA的各种理论模型,分析比较了各个模型的特点和适用场合,最终选择完善的Giles理论模型作为本论文分析设计EDFA的理论基础;针对实际实验条件提出了修正的EDFA模型的数值计算方法;创新地提出了增益—噪声系数全局分析法,直观有效地分析了EDFA的增益和噪声系数与掺铒光纤长度和泵浦功率的依赖关系,并对各种EDFA的性能作了全面的比较;第二,介绍了掺铒光纤放大器特性参数的定义与测量方法,重点介绍了噪声系数和增益系数的测量方法及实验装置;介绍了组成掺铒光纤放大器各组件的特性测量方法,重点介绍了测量掺铒光纤参数的方法和实验装置;第三,针对WDM系统对L-band EDFA谱平坦、低噪声、高增益的要求,我们创新地提出了四种不同的L-band EDFA结构,按设计思路可以分为两大类:一类是基于单抽运二级泵浦法,这一类包括在未泵浦掺铒光纤的输入端插入一根布拉格光纤光栅的两段L-band的EDFA的新结构;基于前向ASE光作为二级泵浦源推动下一级EDF工作的泵浦分配、两段级联L-band的EDFA的新结构;基于单根光纤光栅、泵浦分配、两段级联的EDFA;另一类则是基于同时应用前后向C-band ASE作二级泵浦源的双抽运法,如基于前后向ASE光作为二级泵浦源的三段级联L-band的EDFA的新结构。

Eugène Henri Paul Gauguin was born in Paris on 7 June, 1848, the son of Clovis Gauguin, a Republican editor, and his wife Aline Marie Chazal. In 1849, after Louis Napoléon came to power, the family emigrated to Peru. Clovis Gauguin died on the way. His widow and 2 children stayed in Lima with their rich relatives and did not return to France until 1855. On coming back they settled with the uncle Isidore Gauguin in Orléans. In 1865, Paul became a sailor and spent the next three years voyaging between France and South America, and made a voyage around the world. In 1868, Paul joined the navy, which he left after the Franco-Prussian War. Instead, he started to work as a broker's agent in Paris.
