The charm of their combination is presented in the studies of aforementioned systems.

两者结合的魅力在前面提到的研究体系中得到了充分的体现。

The paper studies the rational back aggraclation width of yellow river dike with reliable theory,researches and formulates the finite element reliability program of Monte-carlo filtration for calculate the failure probability of filtration stability for soil body of different distance from slope base of yellow river dike under design flood level,thus determines the rational back aggradation width.

利用可靠性理论对黄河堤防淤背设计的合理宽度问题进行了系统的分析研究，充分考虑了黄河堤防土体参数的随机变异性，研制了蒙特卡洛渗流有限元可靠度程序，用来计算在设计洪水位下距黄河堤防背河坡脚不同距离的地层土体渗流稳定破坏概率，从而确定合理的淤背宽度。

In chapter four, by the concept of negative definite of symmetry interval matrix, methods of analysis of interval matrix and the method of Lyapunov function, the robust absolute stability of Lurie control system with multiple nonlinearities was investigated, and some algebraic sufficient conditions in the form of inequalities of interval matrix were obtained.

在第四章，通过定义对称区间矩阵负定的概念，主要用区间矩阵分析技术和Lyapunov函数方法，研究了具多非线性的区间Lurie控制系统的鲁棒绝对稳定性，我们给出了此类区间Lurie系统鲁棒绝对稳定性的区间矩阵不等式形式的代数充分条件。

In 1992, a three phase double circuit line between Goudey and Oakdale station was reconstructed to six-phase line and was operated commercially by New York state electric and gas. It is a milestone from theoretical research to practical application in the development of six-phase transmission.With the decrease of cultivated land and the environmental problem in china, it is an important factor to improve power transmission density in the construction of electric network, and the predominance of six-phase transmission is obvious in this aspect.

六相输电是多相输电的一种，在国外六相输电技术作为提高输电线路功率传输密度，节约线路走廊空间的重要手段得到了充分的重视，对六相输电技术的研究也取得了很大的进展。1992年，美国纽约电力和天然气公司将Goudey到Oakdale之间的一条双回线路改造成了六相输电线，并且已经投入了商业运行，这标志着多相输电技术已经从理论研究向实际应用迈出了重要的一步。

This thesis takes the Fujian sea fisherman as the Object of study, drawing support from the document data and the field investigation, giving a view upon the politics, economy, culture and so on, emphatically discussing the changes and the characteristics about fisherman"s life, makes a comprehensive research to the fisherman during the time of Ming and Qing Dynasties. Meanwhile,the text attempts to affirm fisherman"s history contribution and the unique fishing culture connotation depending on the fisherman behavior and the Spiritual research.

本文以福建海洋渔民为考察对象，以明清时期为切入点，运用文献与田野调查相结合的方法，着重探讨明清以来福建沿海渔民生产生活的特点及变化，从政治、经济、文化等方面对渔民进行综合性的探索和研究，试图通过对渔民行为和精神层面的研究，充分肯定渔民的历史贡献和独特的渔文化内涵。
