文化差异对修辞学的影响

探讨了英、汉两种语言所反映的文化、用词和修辞形式。语言和文化是密切相关的，而修辞学是一种特定文化的表现，修辞方法因文化而异，文化思维模式决定了修辞学的方法及方式。儒家思想反映了中国文化的思维模式，而亚里士多德哲学反映了英语国家的思维模式。非母语英语课程的学习者总是无意识地把本国语言和文化的修辞形式应用到英语写作中，因此产生学习和交流上的障碍。了解文化差异对修辞的影响，会缩小这种差距。

《孙子兵法》修辞特色述略

《孙子兵法》确实是以其精辟的军事实战思想和军事哲学思想成为世界兵学圣典的。但是，在该书的久远流传中，“语句精练，用词准确”、“辞格多样，灵活自然”、“注重诵读，音韵和谐”的修辞特色也不容忽视。     

法律适用中的语言学研究

法律适用的过程是将法律规则内含的旨意表达出来并使相关人接受、使相关事务得到合理解决的过程,最终使人与人之间的关系归于有序。而人与人之间的关系协调最终是需要通过语言使双方的意图被彼此接受,而法律只是其中的一部分。因此,从语言的角度讨论法律的适用,实质是研究如何使法律更好地得到实施的方法或途径之一。通过研究法律语言的现状从修辞学角度探究法律适用。

China’s Aviation Industry: a Global Partnership Strategy

This article discusses one of the main strategies which China has implemented to develop its competency in the aviation field. It is strategic for China to boost its aviation industry via international cooperation and several models of involvement into the global aviation value chain with leading aviation industries. As it is depicted as a strategy here, it is not necessary to say that a formal strong national strategy in encouraging exists. Actually, it is clearly a way China’s aero industry takes to develop its competency and business at the context it encounters. From an observer’s perspective, it is indeed a critical strategy. This article describes this strategy via the context, policies, program cases, as well as the evolution of the cooperation models in order to synthesize the strategy.     

Gene Transfer and the Reconstruction of Life’s Early History from Genomic Data

The metaphor of the unique and strictly bifurcating tree of life, suggested by Charles Darwin, needs to be replaced (or at least amended) to reflect and include processes that lead to the merging of and communication between independent lines of descent. Gene histories include and reflect processes such as gene transfer, symbioses and lineage fusion. No single molecule can serve as a proxy for the tree of life. Individual gene histories can be reconstructed from the growing molecular databases containing sequence and structural information. With some simplifications these gene histories can be represented by furcating trees; however, merging these gene histories into web-like organismal histories, including the transfer of metabolic pathways and cell biological innovations from now-extinct lineages, has yet to be accomplished. Because of these difficulties in interpreting the record retained in molecular sequences, correlations with biochemical fossils and with the geological record need to be interpreted with caution. Advances to detect and pinpoint transfer events promise to untangle at least a few of the intertwined histories of individual genes within organisms and trace them to the organismal ancestors. Furthermore, analysis of the shape of molecular phylogenetic trees may point towards organismal radiations that might reflect early mass extinction events that occurred on a planetary scale.     

Effectiveness of the Nash strategies in competitive multi-team target assignment problems

The Nash strategy in game theory has often been criticized as being ineffective in competitive multi-team target assignment problems, especially when compared with other simplistic strategies such as the random or greedy targeting strategies. This criticism arises from the fact that the Nash strategies may yield unpredictable results when paired with non-Nash strategies in non-zero sum games. In addition, the Nash equilibrium is generally more difficult to compute than strategies which do not attempt to anticipate the strategy of the other side. The authors seek to show that in multi-team target assignment problems the Nash strategy is superior to such simplistic strategies while also remaining computationally feasible. To demonstrate this point, an attrition model was considered, consisting of two teams of nonhomogeneous fighting units simultaneously targeting each other and compare the outcomes when various combinations of four targeting strategies are used on each side. The four strategies are: 1) the random strategy where each unit selects its target randomly, 2) the unit greedy strategy where each unit chooses the target that optimizes its own performance only, 3) the team optimal strategy where the units coordinate their choice of targets so as to optimize the overall team performance while ignoring the possible strategy choices by the other team, and 4) the team Nash strategy, calculated under the assumption that the other team is also using a Nash strategy. Because the computational requirements for calculating the team Nash strategies may become unfeasibly large, an efficient method was discussed for approximating the Nash strategies using a neighborhood search algorithm called unit level team resource allocation (ULTRA). The results were compared for all 16 possible combinations of these four targeting strategies and show that for each team the Nash strategy outperforms all other strategies irrespective of the strategy employed by the other team     

一种新的小型无人机飞行控制策略研究

针对传统控制策略对小型无人机系统计算能力要求高、结构要求复杂的特点,提出了一种新的控制策略,即只采用角速率陀螺和GPS传感器配置,控制器结构采用两层回路实现(即角速率回路和轨迹控制回路)。利用输出反馈二次调节器设计方法得到了相应的控制器结构参数。最后,通过仿真比较了新控制策略和传统控制策略在轨迹控制过程中的控制效果。仿真结果表明,所提出的控制策略具有与传统控制策略相似的控制效果,但新策略下的控制器结构和系统复杂程度都更简单。
