失眠患者的耳穴诊断及耳穴贴压疗效观察

[目的]探索大学生失眠患者的耳穴敏感点及耳压治疗效果.[方法]对43例大学生失眠患者和40例健康大学生作了耳穴敏感点测定,同时对患者进行了耳穴贴压治疗.[结果]失眠患者阳性例数在65％以上的敏感点有皮质下、心、神门、枕、垂前、脾等6点,而健康大学生上述6点阳性例数明显减少,经统计学处理,两组有显著性差异(P<0.01).失眠患者治疗后痊愈8例,显效13例,好转18例,无效4例,总有效率为90.7％.[结论]耳穴贴压敏感点治疗失眠疗效满意,可推广应用于学生患者.     

三角形packing问题中零自由度动作的分类

三角形packing问题中三角形可以进行连续平移和旋转,如果不对三角形放置动作进行限制,则计算将无法实现。本文提出了零自由度动作概念,并对它进行了详细的分类,为求解三角形Packing问题建立了一个接近客观情况的模型。     

Made in China: the cultural logic of OEMs and the manufacture of low‐cost technology

Abstract

This paper investigates the conditions of the manufacture of low‐cost technology in China with the examples of ‘pirated’ VCD players, ‘no‐name’ DVD players, and Shenzhen’s development as a techno‐urban city. It emphasizes the significance of the cultural logic of original equipment manufacturers (OEMs) and argues that the various transformations and deflections that are derived from ubiquitous OEM experiences have gone beyond the original model of an authorized OEM, experiences that are to some extent embodied in the transgression of brand name and patent hegemonies, which are mainly controlled by high technology companies. OEMs have been associated with China’s current imperative and uninhibited development of low‐cost technology capitalism. ‘Made in China’ signifies the production of any product, legal or illegal, for transnational high technology giants or domestic technology manufacturers. Learning to ‘become an OEM’ in China has partly resulted in excessive technological mimesis that may be part of an unauthorized, underground economy that is based on low‐cost technology. Based on the Shenzhen experience, part of this study will show industrial production‐oriented OEM cultures in which illegal operations and counterfeit trade are incorporated, even in city projects that are shared by municipal governments and Chinese technological companies, and undergo spatial restructuring in the development of the economy, consumerism, and urbanism.

陶渊明的固穷之志论

在陶渊明一百二十多篇诗歌中,涉及“固穷”的占三分之一强。特别是《咏贫士》组诗,对此表现尤为集中。在写作《咏贫士》前后是诗人内心矛盾极为激烈而急需寻找心理慰安的时候,此组诗正是诗人在能否将固穷之志坚守到底的矛盾斗争中升华的结晶。“固穷”在陶渊明的思想和创作中都占有极为重要的地位。它对陶渊明的思想和人生道路产生过重要影响,成为他精神的重要支撑。那些以《咏贫士》为代表的表现固穷题材的诗歌,直接影响到陶渊明后期创作的风格。     

论现当代农村小说的“安土意识”

现当代农村小说在清除安土意识过程中的表现出为的不彻底性，一方面它不断地清理着农民的安土意识，另一方面又受到深层次安土意识的制约。章分析了造成这种现象的原因，指出了较为彻底地清除安土意识所要注意的问题。     

论中国当下的艺术审美教育

审美教育是我们在任何一个时代都无法回避的问题,特别是在大众文化背景下,审美教育特别是艺术审美教育显得尤为重要。针对目前审美教育缺失的现状,我们应该坚持核心坚守与开放空间的原则,建立具有时代特色的艺术审美教育体系。通过艺术审美教育实现人类和谐全面的发展。     

Research on the methods of detecting and removing slide valve failure

Various ways for detecting slide valve failure are discussed in the paper. Specifically, a new method for detecting slide valve sticking state is first presented. The method does not depend on any special sensor and is only based on the detection of oscillation current wave within a valve coil. Results of theoretical analysis and experimental research are given for comparison. In order to remove a slide valve sticking online, a concept and method of “electrical hammer” is introduced. At last, an application example of the methods is discussed. In fact, it is an electro-hydraulic turbine system with failure diagnosis, fault-tolerant and trouble removal functions.
