具有模糊系数的多目标模糊正项几何规划的解法

多目标几何规划是解决一些最优化问题的强有力工具,当问题中的参数为模糊数时,目标值也应该是模糊数。本文提出求解系数是模糊数的多目标模糊正项几何规划的算法,首先利用线性加权的方法将问题转化为单目标模糊正项规划问题,再利用Zadeh的扩张原理与对偶原理将单目标模糊正项规划问题转化为两个普通的正项几何规划。

Orogen-parallel extension in Himalays:Is it the indicator of collapse or the product in process of compressive uplift?

Extensional structures developed extensively in Himalaya with their strikes perpendicular to that of the orogenic belt. The studies of such structures in Qusum, Burang, Lhozhag, Nyalam and Yadong show that they represent an orogen-parallel extension. The basins produced by the extension experienced orogen-perpendicular compression during their formation. The ages of the extension rang from 16 to 13 Ma and coincide with the intensive compressive stage in Southeastern Asia. Therefore, the extension is syn-shortening and the dominate tectonic movement in Himalaya was compression and uplift during the extension. The extension was the partition of compressive deformation rather than the indicator for the collapse and falling of the Tibetan Plateau.

从能指和所指的角度看隐喻的符号学翻译

为了更好地实现英汉语之间隐喻的翻译,特选取符号学的符号概念来研究不同来源的隐喻的翻译．具体从能指和所指两个方面来分析不同层面,包括字词、句子和语篇隐喻的翻译,提出了几种从符号的角度进行隐喻翻译的具体翻译方法．研究发现,从符号的角度能更准确更恰当地实现英汉语隐喻的翻译,希望能给符号学与语言翻译实践进一步的结合带来一点借鉴和启示．

非线性系统的高增益滑模输出跟踪

Extension strategy-tactics-planning (ESTP), based upon the science of Extenics, is established for the purpose of solving contradictory problems. In this paper, the fundamental thoughts, theories and methods of ESTP are introduced concisely. The highlights of ESTP are that the techniques, used in the case of tackling such problems as how to generate the ideas of strategy-tactics-planning, how to completely analyze the resources, how to exploit extension resources, how to transfer the incompatible into the compati-ble, and how to transfer the opposite into the co-existent, are developed in a formalized way. And regarding the practices of ESTP, the applications of ESTP in resource integration, project, market development, and the prevention and handling crises are presented.
