For fiber reinforced ceramic matrix composites（CMCs）,oxidation of the constituents is a very important damage type for high temperature applications. During the oxidizing process,the pyrolytic carbon interphase gradually recesses from the crack site in the axial direction of the fiber into the interior of the material. Carbon fiber usually presents notch-like or local neck-shrink oxidation phenomenon,causing strength degradation. But,the reason for SiC fiber degradation is the aw growth mechanism on its surface. A micromechanical model based on the above mechanisms was established to simulate the mechanical properties of CMCs after high temperature oxidation. The statistic and shearlag theory were applied and the calculation expressions for retained tensile modulus and strength were deduced,respectively. Meanwhile,the interphase recession and fiber strength degradation were considered. And then,the model was validated by application to a C/SiC composite.

An important motif in science fiction films is the encounter between different species--usually between human kind and alien kind. In films of this type, both anxieties and hopes are imagined and exhibited. By examining three science fiction films made in Hong Kong, Taiwan, and Chinese mainland in the late 1970s and early 1980s--that is, The Super Inframan （Zhongguo chaoren, 1975）, God of War （Zhanshen, 1976）, and Death Ray on Coral Island （Shanhudao shang de siguang, 1980）--this paper analyzes the ideologies and anxieties behind such encounters. These films present different ＂Chinese＂ pictures, revealing the fluidity of Chineseness, as well as the variety of frameworks within the genre of Chinese-language science fiction films. In this time of globalization, it is important to examine these early science fiction films in order to explore the relation between local social concerns and their artistic presentation.

In a pH 2.4 Britton-Robinson buffer medium, the anthracycline antibiotics mitoxantrone（MXT） could react with metal ions such as Pd（Ⅱ）, Co（Ⅱ） and Cu（Ⅱ） to form 1：2（molar ratio） cationic chelates, which further reacted with the anionic dye titan yellow to form 1：2 ternary ion-association complexes by electrostatic interaction. As a result, the intensity of resonance Rayleigh scattering（RRS） was enhanced greatly. These RRS spectral characteristics of various metal ion systems were similar, and the maximum RRS wavelengths were all located at 454 nm. But the increments of RRS intensities were different in the series of Pd（Ⅱ）〉Co（Ⅱ）〉Cu（Ⅱ）. The enhanced RRS intensities were proportional to the concentration of MXT in a range of 0.03-2.4μg/mL and the detection limit（3σ） was 0.009μg/mL for the Pd（Ⅱ） system. In this study, the optimum conditions of the reactions and the effects of foreign substances were investigated, in addition, the composition and reaction mechanism of ion-association complexes were discussed. Thus a highly sensitive, simple and rapid method is proposed for the determination of MXT in urine and serum samples.

Background： Self-sustained oscillations are a ubiquitous and vital phenomenon in living systems. From primitive single-cellular bacteria to the most sophisticated organisms, periodicities have been observed in a broad spectrum of biological processes such as neuron firing, heart beats, cell cycles, circadian rhythms, etc. Defects in these oscillators can cause diseases from insomnia to cancer. Elucidating their fundamental mechanisms is of great significance to diseases, and yet challenging, due to the complexity and diversity of these oscillators. Results： Approaches in quantitative systems biology and synthetic biology have been most effective by simplifying the systems to contain only the most essential regulators. Here, we will review major progress that has been made in understanding biological oscillators using these approaches. The quantitative systems biology approach allows for identification of the essential components of an oscillator in an endogenous system. The synthetic biology approach makes use of the knowledge to design the simplest, de novo oscillators in both live cells and cell-free systems. These synthetic oscillators are tractable to further detailed analysis and manipulations. Conclusion： With the recent development of biological and computational tools, both approaches have made significant achievements.

For a long time, Chinese export enterprises were afflicted by the vague WTO rules of non-market economy under anti-dumping investigations. On 15 July 2011, the Dispute Settlement Body （＂DSB ＂） of the WTO published the report of the Appellate Body on the dispute called ＂European Communities --Definitive Anti-dumping Measures on Certain Iron or Steel Fasteners from China＂（DS397）. In this article, it is to reason four questions, i.e., （i） the scope of article 9（5） of the Basic Anti-dumping Regulation of the European Union; （ii） whether sampling as described in the second sentence of article 6.10 constitutes the only exception to the principle laid down in the first sentence; （iii） whether a state may be seen as a producer unless individual exporters can demonstrate their independence from the state; （iv） interpretation of the word ＂impracticable＂ under articles 9.2 and 6.10, the DSB finally concluded that the EU acted inconsistently with articles 6.10 and 9.2 of the Anti-dumping Agreement with respect to article 9（5） of the Basic AD Regulation of EU, which refused to give each known NME exporter or producer individual duty treatment. To some extent, this case might clarify the NME issue in the WTO, change the deJbctive situation, and be considered as a milestone for the promotion of justice under a free and rule-oriented multilateral trade system.

胡庚申的翻译适应选择论是一个以译者为中心的翻译理论，其主要观点是“翻译即适应与选择”，翻译的实质是“译者适应翻译生态环境的选择活动”。葛浩文，美国著名翻译家，也是目前英语世界地位最高的中国当代文学翻译家之一。他卓越的双语和双文化能力使其译本在西方国家广为流传，他为传播中国文化，促进中西文化交流做出了不可磨灭的贡献。本论文以翻译适应选择论为理论基础，探讨了葛浩文在英译莫言小说《丰乳肥臀》的过程中，为适应其所处的翻译生态环境而做出的适应与选择。本论文认为，葛浩文所处的翻译生态环境包括两个部分：源文/源语呈现出来的世界以及译语呈现出来的世界，前者主要包括源文、源文作者和汉语及汉文化等要素，后者主要包括译语读者、译语意识形态和出版商等要素。本论文分析了葛浩文在译前和译中两个阶段所做出的适应和选择：在译前阶段，由于葛浩文对中国当代文学具有浓厚的兴趣，并且拥有优秀的双语双文化能力，他成为莫言小说的译者。译前阶段是他对源文/源语呈现出来的世界所做出适应的一个过程。在译中阶段，葛浩文主要对译语呈现出来的世界进行适应，同时相应地选择出适合的翻译策略和技巧。在《丰乳肥臀》的翻译中，葛浩文所用到的翻译策略及翻译技巧是多样化的，就翻译策略来讲，归化和异化都有使用，而在翻译技巧方面，更是不胜枚举，重写，省略，加注等方法均有使用。本论文得出结论，文学翻译并非单纯的语言活动，而是与译者周围各种因素密切相关的一种自然生态活动，译者在翻译过程中所做出的各种选择必须要能够适应其所处的翻译生态环境。本论文旨在为葛浩文及其英译小说的研究开辟一条新的研究路径，同时为目前中国文学的英译提供些许建议。
