IntroductionIn composite applications, 3D woven fabrics used forreinforcing preforms are usually in plate forms. But insome special applications, 3D woven preforms need to bemade with changing cross sections so as to manufacturecomposites with special shapes. Research on 3D wovenstructures and their weave design methods should be firstdone before 3D woven preforms with changing cross sections can be woven on looms.To realize woven fabrics with changingcross secti… 相似文献

Gelman and Bloom found that adults and children's object naming was sensitive to how an object was created (man-made or not), but they did not reveal on which specific level of conceptual system this effect was. Using a free-naming task and a force-choice task, two experiments were conducted to test a hypothesis that this effect was specifically on domain level ("artifact/non-artifact" distinction). In Experiment 1, participants were asked to name shortly-depicted objects, rate their confidence, and report their reasons for each naming response. Results showed that most of the naming responses in "man-made" condition were in artifact domain, and most in "natural" condition were in non-artifact domain, although in both conditions names were very divergent on basic level. In Experiment 2, another group of participants were asked to choose one from two names (one in artifact domain and the other in non-artifact domain) to match the same shortly-depicted objects presented in the first experiment. Re-sults of Experiment 1 on domain level were replicated in Experiment 2. These convergent findings supported the hypothesis that the effect of object's origin is specifically on domain level of conceptual system of objects. Reasons explicitly reported for naming responses in Experiment 1 suggested that participants might automatically infer objects' functions in "man-made" condition but not in "natural" condition. Here the function-based hypothesis of artifacts classification is discussed. 相似文献

翻译研究早已关注语篇和语境,语篇翻译研究也已注重语境,但对物理语境和社交语境关注较多,对心理语境关注甚少。由于心理语境对其他语境存在深层制约作用,因此有必要分析其对翻译语篇的影响。从逻辑思维差异出发,以心理语境为中心来分析汉译英中的翻译语篇问题,是进行这方面研究的一种尝试。 相似文献

Adeno-associated virus (AAV) is a promising viral vector and meets most requirements of being a safe biological agent. However, the commercialization of AAV has been hampered due to the limitation of large-scale production, and only a small number of clinical trials have been launched. In recent years, progresses in scalable manufacturing of AAV have dramatically improved AAV- based clinical researches, and have assisted the develop- ment of investigational drug products. An AAVl-based investigational product, Glybera, has been formally approved by European Commission for the treatment of lipoprotein lipase deficiency (LPLD). Glybera was the first gene therapy product in the western world, and the pro- duction process involves a scalable baculovirus-insect cell system. However, many problems still need to be solved to improve the productivity and quality of AAV. The present review gives critical insights into current state-of-the-art scalable producing methodologies of AAV, such as bacu-lovirus-insect cell system, HSV complementation system, and Ad complementation system, along with a discussion on the problems, solutions, and developmental trends.Novel AAV-producing platforms in Saccharomyces cere- visiae and vaccinia virus complementation system will also be discussed. 相似文献

运用DEA-Malmquist指数,测度了1996—2010年中国大陆30个省市高技术产业全要素生产率的变化和差距,并对其影响因素进行了分析。研究表明:技术进步在各地区差异明显,但各地区全要素生产率的增长具有趋同的趋势。相比东部地区,中西部地区技术效率对全要素生产率的推动作用更为明显。从全要素生产率的影响因素来看,科技活动人员、对外开放水平对全要素生产率的影响为正,市场化程度对全要素生产率的影响为负,研发强度、政府管理水平对全要素生产率的影响并不显著。 相似文献

摘要: 针对多处理器片上系统 (Multiprocessor System on chip,MPSoC) 的通信优化技术--通信流水线和消息聚合,其过度使用可能会导致系统同步开销上升从而带来整体系统性能降低的问题,提出了基于整数线性规划(Integer Linear Programming, ILP)的优化策略.该策略以综合优化系统通信和同步开销为目标,通过对通信流水线技术和消息聚合技术的合理规划,使系统性能达到最优.实验结果表明,基于ILP的通信优化策略能够充分发挥通信优化技术的优点,使系统性能显著提升.
