Int J Adv Manuf Technol (2013) 68:187–196 DOI 10.1007/s00170-012-4718-7 Machining deformation prediction for frame components considering multifactor coupling effects Z. T. Tang T. Yu L. Q. Xu Zhanqiang. Liu Abstract : The machining deformationprediction model was developed considering multifactor coupling effects includingoriginal residual stresses, clamping loads, milling mechanical loads, millingthermal loads, and machining-induced residual stresses. The machiningdeformation of a true frame monolithic component was predicted by this model.To validate the accuracy of prediction model, deformations also were measuredon a coordinate measuring machine. The deformations predicted by the model showa good agreement with the experiment ’ s results. The deformation prediction model can providean effective way to study further control strategies of machining deformationsfor monolithic component. Keywords : Machining deformationprediction.

人工智能专家Minsky在1975年提出了Frame这一概念，用于描述专家系统中的典型场景。随后，美国语言学家Fillmore将其引入语言学，1977年形成Frame Semantics。Talmy提出了event-frame，以及操作模型：windows of attention，gapping。Goldberg发展出Construction Grammar。Lakoff分析了政治辩论中的framing，将框架语义学应用到政治分析中。

文题 “教、管、学”的分层次多模式探新——“自主、互动、积累”良性循环 修改 英文文题 A Probe into the Multi-Layered, Multi-Modal of"Teaching, Management and Learning”：the Virtuous Circle Program of "Autonomy, Interaction and Accumulation" 修改 作者 邹顺鹏;邹晓辉; 修改 摘要 如何在课堂上实施“教、管、学”分层次多模式探新？笔者认为：首先，需要认清事实。在笔者看来，只有自主学习才能做到教是为了不教;因为教无定法、学无止尽，所以须强调互动并注重积累。然后，分两阶段实施“自主、互动、积累”即“教、管、学”三环节良性循环方案。本文重点从整体上检验了第一个环节的实际效果，即通过调查对比和实证分析，科学地验证笔者在2010秋至2011春两学期三个班的大学一年级的公共英语课尝试“创造性合作型生产式”智慧融通活动的初步结果，为今后进一步系统地认识并全面推广它打下了具体实践的感性基础。研究结果表明：大学英语课堂“教、管、学”分层次多模式探新，对学生英语自主学习意识及能力乃至学习兴趣的发展的确有显著影响。 修改 英文摘要 How to put into action of a probe into the Multi-Layered, Multi-Modal of "Teaching, Management and Learning” in the classroom? The authors think as follows: First and foremost, we need to know the truth. In the authors' opinion, only through autonomous learning can we achieve the result that The Purpose of Teaching Is Not to Teach. Since There Is No Universal Teaching Method and There Is No End to Learning, we must emphasize interaction and focus on accumulation. Besides, we need to put into action of the virtuous circle program of "autonomy, interaction and accumulation", which is equivalent to three aspects of "Teaching, Management and Learning”. This article focuses on examining the practical effect of the first aspect from the overall perspective, which means verifying scientifically the preliminary results of The Creative, Cooperative and Productive Activities of Intellectual Integration during the authors’ experiment towards the three public English classes of the freshman in the two semesters from autumn 2010 to spring 2011 through investigation, comparison and empirical analysis. This lays a perceptual solid foundation concerning the practice for further systematic understanding and comprehensive popularization. The results show that: The searching into the Multi-Layered, Multi-Modal of "Teaching, Management and Learning” in the English class does have a significant impact on college students’ awareness and ability of autonomous learning, as well as the development of their learning interest. 修改 关键词 自主学习;互助活动;知识积累;实证研究 修改 英文关键词 Autonomous Learning; Interaction; Knowledge Accumulation; Empirical Research 修改 原稿 WORD (876.5 KB) PDF (1.07 MB) 图1 全局关系和“教、管、学”宏观导向的示意图 图2 同学们在微观上协同操作的生词和带例句的生词“双列表”格式的示意图 图3 可融通融合多种教学组织形式的宏观总量控制模型的示意图 图4 微观程序控制示意图 图5 借助汉语表达的人机协同计算系统的双语并列标注的标准化宏观知识库示意图 图6 依托宏观知识库而由学生根据自身情况可选用个性化微观知识库的情形示意图
昨天在中科院听了两场学术报告，上午是山东大学嵇少林教授作的题为“ Ambiguous Volatility, Possibility and Utility in Continuous Time ”的报告，下午是新加坡国立大学Shen Zuowei教授作的题为“MRA-based wavelet frame and applications”的报告。 巧的是这两位老师之前不久都在北大作过报告，一个是在理科一号楼1418，一个是在北大国际数学中心。 嵇老师是概率和金融数学方向的，对于我而言这个内容不是很懂，但是能感觉到从理论到实际应用，报告人及其团队所作的工作很好。沈老师是逼近论出身，研究小波、稀疏表示和图像处理的，这是我所比较熟悉的，听得不住赞叹，惊诧于结果之漂亮，忍不住在沈老师报告结束后提问时间举手请教，并在报告结束后跑上前去拷了报告ppt回去好好学习研究。 听报告之最大感受：要有持续性的工作，理论功底一定要扎实，应用一定要有实际意义。 后记： 反省自己的研究团队，目前处于二者的交界处，就看如何能更好地协调好二者的关系了。
