广州医学院校中医学生与西医学生对中西医结合认识的调查报告

建国以来,我国大力致力于培养中西医结合型人材,然而到目前为止,关于中西医结合的概念在医学层面上仍达不到统一的共识,对于当今的医学生们,他们对中西医结合了解有多少,他们如何看待中西结合,中西医结合课程所起的作用有多大等等,这些都非常值得我们关注。为此,2005年6月份期间对广州市五所医学院校的学生进行了有关问卷调查。     

特需医疗服务发展意向研究概述

我国特需医疗服务发展已近20年,尽管其在满足较高层次的医疗保健需求方面确实起到了积极的作用,但同时在特需医疗服务的内涵、服务内容和承担主体等问题上却始终存在着较大争议。本研究从剖析各位学者对上述问题的不同观点入手,对特需医疗服务的供需双方进行意向调查,在此基础上探讨我国特需医疗服务发展的基本思路,为促进我国特需医疗服务的良性发展提供决策的参考依据。     

危险性分析在大学生亚健康状况研究中的应用

亚健康状况在大学生中已经相当普遍,并且严重危害大学生的健康成长。通过应用危险性分析方法,描述了亚健康状况的危害特征及暴露情况,在此基础上概括出亚健康的成因,并提出针对性的对策来解决亚健康所带来的危害,从而帮助大学生实现从亚健康向健康的转化。     

试论如何运用系统论原理认识细胞

运用系统论的原理分析了细胞的形态、结构与功能.细胞是生物体结构和功能的基本单位,具有多样性和统一性.细胞系统是复杂的物质系统,具有层次性、整体性、动态性及开放性等特征.应用唯物辩证法系统论的原理可以对细胞系统做出更新、更全面的诠释.     

精神医学中的信息系统控制原理

精神医学是临床医学的一个分枝,是高度复杂的一门科学,站在哲学的角度反思,信息系统控制科学方法渗透于精神医学的历史发展过程和临床工作的资料收集、诊断、治疗等各个环节,以及精神医学的科研工作中,还启迪着我国精神卫生事业的发展方向.     

小学生自我调节学习的特点

本文采用学业自我调节问卷,探讨了小学四、五、六年级学生自我调节学习的特点。结果表明,不同年级小学生在自我调节学习的外部调节、摄入性调节、认同调节和内部动机维度上存在差异;不同调节类型对学习成绩有影响;不同年级、不同调节水平对数学成绩有显著影响,在语文成绩上未达显著;最后,本文对于该方向的未来研究给予了展望。     

On value and culture

Value stands for the significance of things, and concepts of value are ideas, opinions and attitudes about what kind of things are significant. Studies on the concept of value cannot be separated from culture. Every society has its own distinct culture and concept of value shared by its people. The relationship between concept of value and culture shows that the building of the concept of value must be based on culture. Developing culture, providing excellent products of culture and better humanitarian environment are the premise for people’s possession of the correct concept of value. __________ Translated from Hebei Xuekan 河北学刊 (Hebei Academic Journal), 2005 (1) by Dong Lihe     

飞行学员自我妨碍倾向与竞技应对方式研究

以206名飞行学员为被试,采用问卷法对自我妨碍倾向与竞技状态下应对方式的关系进行研究。结果表明:(1)自我妨碍倾向与想象、努力付出等积极应对方式呈负相关关系,与情绪发泄、疏远、分散注意和放弃等消极应对方式呈正相关关系。(2)低自我妨碍倾向的飞行学员更多地使用想象、努力付出和逻辑分析等积极的应对方式;高自我妨碍倾向的飞行学员更多地使用情绪发泄、疏远、分散注意和放弃等消极的应对方式。     

Influence of aging pathways on the evolution of heterogeneous solute-rich features in peak-aged Al-Mg-Si-Cu alloy with a high Mg/Si ratio

We report on a study of the influence of aging pathways on the evolution of solute-rich features in peak-aged Al-Mg-Si-Cu alloys. The concentration and partitioning ratios of Mg, Si and Cu and Mg/Si ratios in the heterogeneous solute-rich features all increase with increasing size, with Si exhibiting the highest partitioning ratio, but notably these ratios change dramatically depending on the aging pathway selected. Accordingly, the short-time age hardening response can be enhanced by promoting both homogeneous and heterogeneous precipitate nucleation, while simultaneous improvements in peak-aged strength and elongation can be attained by a vacancy-assisted aging pathway.     

Effect of heat treatment on the microstructure and mechanical properties of spray-formed 7055 aluminium alloy

7055 Al alloys samples were prepared by spray forming and hot-extrusion followed by two different aging treatment procedures. Their different distributions of GP zones, and nanoscale precipitates η′ (MgZn) and η (MgZn₂) are extensively investigated by transmission electron microscope (TEM). The mechanical properties, including tensile strength, Vickers hardness and elongation of both aged 7055 Al alloys, have also been measured and analysed. It is found that T6 and T76 aging treatment results in quite different microstructure and mechanical properties. The outstanding performance of the 7055 Al alloys after T6 aging treatment is attributed to nanoscale semi-coherent dispersion precipitates.
