Section two elaborates the structure of a simple model on static yield curve of zero-coupon bond. According to the difference of constitution principle, the dissertation divides the numerous static models into direct ones and indirect ones. On the basis of setting forth the different constitution thoughts of two methods, it compares the merits, shortcomings, and the application scopes of the two methods. Spline model is the most common indirect method, and is the study emphasis of this section, especially its three key approaches that are defining the rank of function, the subinterval number to be divided, and knot of each subinterval, which are fully elaborated in the dissertation.

The research work presented in this dissertation focused on developing the scheme and techniques of OPCPA. This dissertation gives the results of the theoretical and experimental investigation on OPCPA scheme. The validation of OPCPA at high energy level was demonstrated successfully. And some important results were achieved. Several key techniques related to developing table-top ultra-intense and ultra-short OPCPA laser system were put forward, for example, the generation of femtosecond seeding pulses, the precisely temporal synchronization of the pump and signal pulses, the pulse stretching and recompression, the OPCPA process with high energy conversion efficiency and etc. Based on the integration of these key techniques, a 1.46-TW/153-fs OPCPA table-top ultra-intense and ultra-high laser system has been developed, which, to the best of our knowledge, has generated laser pulses with the shortest pulse duration and the highest peak power among the joule level OPCPA systems in the world.

本学位论文工作主要是瞄准 OPCPA 这一国际上提出不久并处于初级阶段的新概念，重点开展了 OPCPA 新原理的理论模拟、实验验证，以及基于 OPCPA 新原理的小型化超强超短激光系统的研究与发展，创造性地解决关键科学技术问题，建立并发展相关关键科学技术，如超短脉冲种子源的产生、小型化强激光泵浦源的研制及其脉冲的整形、信号光与泵浦光的精确同步、高效率光学参量放大及高保真脉冲展宽与压缩等关键技术，并在单元技术的总体集成方面取得了重大创新性进展与突破性研究成果，获得了国际上高量级泵浦条件下 OPCPA 激光研究中峰值输出功率最高且脉冲宽度最短的总体领先结果。

The first part states in a comprehensive way the research on Zhou Zuoren so as to define the purpose, methodology and significance of the dissertation. The second part analyzes the experience of Zhou's self-culture creation from a personal angle-Yue culture in Zhejiang gave Zhou a perceptual knowledge of folklore, while the idea of world folklore gave him a rational cognition of folk' culture. The combination forms a dual folklore. The third part observes Zhou Zuoren's examination of literarure from folklore's perspective as well as its pioneering significance. The fourth part explores in a further way Zhou's perspective of folk culture, and analyzes the method he has established to conduct literary criticism from the angle of folklore as well as his research on Chinese Culture. The fifth part analyzes the impacts folklore theory and folk culture have on the formation of Zhou' literary ideas, focusing more his folklore interpretation and humanism perspective about the origin and hist ory of literature, also his literary aesthetic standards about "ordinary humanism" and "loving amusement" from the position of folklore. The sixth part expounds Zhou's achievement in combining literature and folklore and explores the consistency of their focus on human, thereby presenting a complete picture of Zhou's literature. The last part generalizes the revelation drawing from the research done in this dissertation.
