Calculation of Young's Modulus and Coefficient of Linear Expansion on Several Solid Solution with Cubic Structure

杨氏模量和线膨胀系数是表征金属材料重要的物理量。但是，目前已有的二元及多元合金固溶体的杨氏模量和线膨胀系数的实验数据十分有限。因此，利用合理的理论模型来实现对杨氏模量和线膨胀系数的计算并建立性能数据库十分重要，能够为材料设计提供必要的基础信息。本课题组在应用相图计算技术建立热力学数据库和指导合金的成分设计方面取得了不错的成效。本研究基于相图计算的研究方法，考虑温度和成分两个变量的影响，开展合金溶体相的杨氏模量和线膨胀系数的计算。其具体研究成果如下： (1)借鉴计算相图(CALPHAD)方法的研究思路，构建了二元及三元合金溶体相的杨氏模量和线膨胀系数的计算模型。 (2)运用杨氏模量的半经验模...Young's modulus and coefficient of linear expansion are the important physical properties of metal materials. But experimental data of the binary and multicomponent alloy solid solution is limited. Therefore, establishing reasonable theoretical model to calculate young's modulus and linear expansion coefficient is very important for establishing the property database. In our group, we have achieve...学位：工学硕士院系专业：材料学院_材料学学号：2072012115004

Acoustic measure of fundamental frequency during three speech tasks in vocally healthy children

The present study examined the fundamental frequency (F0) during three speech tasks in a group of vocally healthy children. The study also compared the reliability of different speech tasks for eliciting F0. Fifty-six vocally healthy children (31 boys and 25 girls) between the ages of 7.0 and 10.11 years participated in this study. Each child completed three speech tasks used to elicit a voice sample for subsequent analysis of fundamental frequency (F0). The tasks included: (a) sustained vowel /a/ prolongation, (b) repeating a sentence, and (c) reading aloud a passage. Two types of reliability, between-trial and between-day reliability, were compared across speech tasks. Results revealed significant difference in F0 between the three speech tasks (p = 0.01). Post hoc comparisons revealed that vowel task elicited significantly higher F0 values than the passage task. Passage reading task yielded the highest intra-class correlation coefficient values for both between-trial and between-day reliability. The results provide some empirical data for standardizing voice assessment protocol for school-age children.published_or_final_versionSpeech and Hearing SciencesBachelorBachelor of Science in Speech and Hearing Science

渤海海峡跨海通道景观设计与旅游规划研究

渤海海峡跨海通道建设项目既是21 世纪世界级的重大交通项目,也是贯通山东半岛与辽东半岛的重大社会性基础设施项目。除大桥本身设计方面需要解决的关键技术问题外,项目整体规划设计应按照国际一流水平标准,项目的各种设施和生态修复等工程应该在工艺设计、景观设计等方面精心雕琢,打造新型隧桥文化与旅游文化;并以高水平通道规划和建设带动长岛和通道两端的旅游资源保护和旅游开发建设,打造跨越渤海海峡的海上旅游大通道和世界级旅游景群,使跨海通道建设水平和知名度提升,生态环境更趋良好,社会和环境功能更趋完善

Study on the regulation of large scale ecological tort

生态破坏突发事件或积累性的生态破坏行为不仅给生活于生态系统中的人们带来了巨大的人身损害以及财产损失，还给生态环境带来了巨大的损害。生态侵权课题具有广泛的实际运用前景和深入的科学研究价值，但截止目前，国内外学者对此类问题的研究尚处于起步阶段。笔者在前言中通过结合几则案例，引出本文主题，并分为三章来探讨生态侵权理论基本框架的构建，以期为未来该理论的发展提供参考依据和理论基础。 第一章是大规模生态侵权的理论概述。这一章主要探讨大规模生态侵权的概念及特征，分析大规模生态侵权产生的原因，同时通过比较、分析发达国家的相关经验探讨对我国的启示。笔者认为“大规模生态侵权”发生的前提是造成生态系统中的个体存在...Ecological damage incidents or cumulative ecological destructions in ecological system not only lead to serious personal injury huge and economic loss, but also bring great damages to the ecological environment.

A Marketing Strategy Research on Canadian North Shore Icewine

2008年金融危机席卷全球，但中国葡萄酒市场却未受全球金融风暴的冲击，仍然保持了高速增长，其中对高档葡萄酒的消费增速最快。冰酒，是高档葡萄酒中的奢侈品，具有“高端小众”的特点，如何做好冰酒的营销工作，是目前众多冰酒经营者面临的共同挑战。北海岸冰酒是加拿大顶级冰酒的代表，由世界最大的葡萄酒商美国星座公司位于加拿大的威克尔酒厂生产，上海建发实业有限公司2007年将这款酒引入中国市场。近两年来，北海岸冰酒的销售业绩远低于预期。本文主要介绍了北海岸冰酒的营销现状，通过分析发现，影响其销售的主要原因是定位。在经过市场细分、目标市场选择后对北海岸冰酒进行了全新的定位，即：“葡萄酒中的奢侈品，贵宾专属的精神...The financial crises of 2008 heat the whole world. While the Chinese wine market was not affected by the crisis and grew very fast, among which the high end wine market increased with a top speed. Among all top wines, Icewine is the ultimate.
