中国革命史教学改革的探索

一、对学科体系和课程功能的思考按照《中共中央关于改革学校思想品德和政治理论课程教学的通知》精神,我校把中共党史改为中国革命史课程已有五年时间了。这样做,不仅增加了历史的长度和宽度,而且通过横向和纵向的对比,有利于对学生进行以中国革命史为中心的历史教育。中共党史、中国革命史(以下简称革命史)和中国近现代史是互有联系而又有区别的不同学科。如果不弄清它们的研究对象,就很难确立它们的学科体系。党史是一门研究中国共产党的历史发展及其规律的学科,它主要反映党自身的活动。革命史是一门研究中国民主革命和社会主义革命进程及其规律的学科,它涉及的范围比党史、工运史、军史等各门专史要宽,要叙述各革命阶级、阶层和各族人民进行反帝反封建斗争、进行社会主义改造的经过,并阐明革命     

以改革总揽全局,把竞争机制引入学校

党的十三大再一次突出强调了教育在社会主义现代化建设中的战略地位,提出了“百年大计,教育为本”,这是历史赋予我们教育战线的光荣使命。高等教育事业则必须适应今后经济建设、经济体制改革、政治体制改革形势发展的需要,深化自身的改革。回顾近几年来学校的工作,如果说有一定的成绩,最主要的经验就是必须以改革总揽全     

中南工业大学教研室工作条例

第一章总则第一条教研室是学校组织教学、科研和师资培养工作的基层组织,它是按照专业、课程(一门或几门性质相近的课程)设置的教学科研的教学人员集体,教研室的增设、撤并要报学校审批。第二条教研室工作应以培养合格的社会主义事业的建设者和接班人为目标,坚持社会主义的办学方向,坚持教学改革,全面贯彻党的教育方针,保证学生在德、智、体诸方面发展。     

学生评价高等教育服务质量实证研究——以湖南高校2008届毕业生满意度调查为例

本研究以利益相关者理论、顾客满意度理论为指导，以本专科院校2008届毕业生为对象，组织学生登录指定的网络链接，填写自制的《学生评价高等教育服务质量评量表》，首次对湖南34所院校的1342名本科生、研究生和高职高专学生进行904评。研究表明，本科生、研究生、专科生总体满意度平均为3．76，相当于百分制的75．2分。专科生满意度相对较高，为3．81；研究生满意度相对较低，为3．73；本科生居中，为3．75。三类学生对课程与教学、个人发展服务的满意度比较接近，而对生活和环境、信息资源、入学和就业、咨询和建议、收费和资助服务的评价差别较大，对个人发展、课程与教学、信息资源服务满意度相对较高，而对入学和就业、生活和环境、咨询和建议的服务较不满意。在最不满意的10个项目中，本科生、研究生和专科生都选择的有“学校的餐饮和卫生环境”、“学校医疗条件和服务”、“校方经常收集我对教育质量的意见”、“学生会代表了学生的利益”。工学和教育类专业学生三个层次的满意度都高于平均水平，法学类专业学生的满意度都低于平均水平。学生满意度与教学评估和大学竞争力评价结果相关度很低，表明学生满意度调查具有不可替代性。建议国家和省级教育行政部门尽早建立我国学生满意度调查和结果的发布制度。     

"服务能力"与高职教育自身建设的导向——以安徽省为例

高职教育自身建设的导向存在谬误的现象需引入“服务能力”的概念来加以更正。当前高职教育服务能力不足表现为对经济、社会建设活动的直接参与度不够、服务不全面；服务弱势人群的意识与行动欠缺；深度服务产业的能力不足。其原因是学校发展思路偏差、缺乏扎实的专业和课程建设、优秀职教人才稀缺。提升服务能力的途径是学校自觉加强能力建设，政府以服务能力为标准评价和指导高职院校。     

“潜课程”和“校园文化”理论是高校后勤服务育人的重要理论依据

“潜课程”理论,属于课程领域的研究范畴,是从教育学的角度提出来的。比较有权威的是胡森,他主编的《教育的国际百科全书》中作了如下解释:潜课程是指那些在课程指导和学校政策方面不十分明确的部分,但却又是学校教育过程中不可缺少而行之有效的组成部分。我们可以将潜课程看作是隐蔽的、无目的的、含蓄的或简直是不被公开承     

高校国防教育是大学生素质教育的重要组成部分

“全民国防教育是新时期我国国防现代化建设的重要组成部分 ;在高等学校开展国防教育 ,是‘教育必须为社会主义现代化建设服务’,包括为国防现代化建设服务的具体体现 ,是教育外部关系规律的客观要求”的理论观点 ,在经过 1985年以来十几年学生军训的实践——认识——再实践——再认识的多次反复之后 ,已经为广大教育工作者所认识和接受 ,并付诸实践。1997年颁布的《中华人民共和国国防法》规定 :“学校的国防教育是全民国防教育基础。各级各类学校应当设置适当的国防教育课程 ,或者在有关课程中增加国防教育的内容。”江泽民同志也明确指出…     

关于实行学生思想政治教育系列化的意见

为将学生培养成为德、智、体全面发展的社会主义事业的建设者和接班人,使学生具有坚定正确的政治方向,学校必须加强学生思想政治教育。近年来,有色系统所属院校在加强和改进学生思想政治工作方面取得了可喜成绩,但也还存在着不少问题。比较普遍的是在学生思想政治教育的计划、内容安排和方法上存在随意性、临时性,“头痛医头,脚痛医脚”的被动局面没有得到根本扭转。要改变这种被动局面,加强学生思想政治教育的主动性、针对性、系统性,实现思想政治教育科学化,实行学生思想政治教育的系列化十分必要。

为贯彻党的“治理经济环境、整顿经济秩序、全面深化改革”的方针,在广告管理中杜绝虚假广告和其他违法广告的发生,中国广告协会在全国广告行业中开展了“重信誉、创优质服务”的活动。经四川省及成都市广告协会充分讨论、认真评选,授予《电焊机》杂志编辑部等21家广告经营单位:四川省及成都市广告业1989年“重信誉、创优质服务”先进单位称号。本刊的广告经营,一贯坚持“信誉第一、质量第一”的思想,注重广告的社会效益和经济效     

再论"教育产业化"

近来关于“教育产业化”、“教育企业化”、“教育市场化”的呼声日见高涨。持这一观点的人们认为教育是产业,教育产业化有利于加速发展教育产业,更好地满足社会对教育的需求。我认为,我国在经济不发达,国家不能为教育提供充分经费的条件下,教育系统适度引入市场竞争机制有利于充分利用教育资源,在有限的时间、空间中产学研更好地结合,但这不意味着“产业化”。“产业化”意指整个社会发展的大趋向,它意味着绝大多数学校转化为产业。结果容易导致全社会教育机构一哄而起,向产业的目标发展。我们在提出目标时,必须考虑教育与社会之间以及教育…     

Effects of Post-weld Heat Treatment on Microstructure,Mechanical Properties and the Role of Weld Reinforcement in 2219 Aluminum Alloy TIG-Welded Joints

In as-welded state, each region of 2219 aluminum alloy TIG-welded joint shows diff erent microstructure and microhardness due to the diff erent welding heat cycles and the resulting evolution of second phases. After the post-weld heat treatment, both the amount and the size of the eutectic structure or θ phases decreased. Correspondingly, both the Cu content in α-Al matrix and the microhardness increased to a similar level in each region of the joint, and the tensile strength of the entire joint was greatly improved. Post-weld heat treatment played the role of solid solution strengthening and aging strengthening. After the post-weld heat treatment, the weld performance became similar to other regions, but weld reinforcements lost their reinforcing eff ect on the weld and their existence was more of an adverse eff ect. The joint without weld reinforcements after the post-weld heat treatment had the optimal tensile properties, and the specimens randomly crack in the weld zone.

Theoretical Analysis for the Motion and Temperature of Melt Droplets in Spray Degassing Process

The motion of melt droplets in spray degassing process was analyzed theoretically. The height of the treatment tank in spray degassing process could be determined by the results of theoretical calculation of motion of melt droplets. To know whether the melt droplets would solidify during spraying process, the balance temperature of melt droplets was also theoretically analyzed. Then proof experiments for theoretical results about temperature of melt droplets were carried. In comparison, the experimental results were nearly similar to the calculation results.     

Growth Kinetics of Single Inclusion Particle in Molten Melts

On the basis of the single-particle framework, a new theory on inclusion growth in metallurgical melts is developed to study the kinetics of inclusion growth on account of reaction and collision. The studies show that the early growth of inclusion depends on reaction growth and Brawnian motion collision, and where the former is decisive, the late growth depends on turbulence collision and Stokes＇ collision, and where the former is dominant; collision growth is very quick during the smelting process, lessened in the refining process, but nearly negligible in the continuous casting process.     

An Easy Way to Quantify the Adhesion Energy of Nanostructured Cu/X(X=Cr,Ta,Mo,Nb,Zr) Multilayer Films Adherent to Polyimide Substrates

An approach based on film buckling under simple uniaxial tensile testing was utilized in this paper to quantitatively estimate the interfacial energy of the nanostructured multilayer films(NMFs) adherent to flexible substrates. The interfacial energies of polyimide-supported NMFs are determined to be *5.0 J/m2 for Cu/Cr, *4.1 J/m2 for Cu/Ta,*2.8 J/m2 for Cu/Mo, *1.1 J/m2 for Cu/Nb, and *1.2 J/m2 for Cu/Zr NMFs. Furthermore, a linear relationship between the adhesion energy and the interfacial shear strength is clearly demonstrated for the Cu-based NMFs, which is highly indicative of the applicability and reliability of the modified models.     

High-Speed Friction Stir Welding of SiC_p/Al–Mg–Si–Cu Composite

A 17 vol% SiCp/Al–Mg–Si–Cu composite plate with a thickness of 3 mm was successfully friction stir welded(FSWed) at a very high welding speed of 2000 mm/min for the first time. Microstructural observation indicated that the coarsening of the precipitates was greatly inhibited in the heat-affected zone of the FSW joint at high welding speed, due to the significantly reduced peak temperature and duration at high temperature. Therefore, prominent enhancement of the hardness was achieved at the lowest hardness zone of the FSW joint at this high welding speed, which was similar to that of the nugget zone. Furthermore, the ultimate tensile strength of the joint was as high as 369 MPa, which was much higher than that obtained at low welding speed of 100 mm/min(298 MPa). This study provides an effective method to weld aluminum matrix composite with superior quality and high welding efficiency.     

Three-Dimensional Growth of Coherent Ferrite in Austenite: A Molecular Dynamics Study

Coherent second phase often exhibits anisotropic morphology with specifi c orientations with respect to both the second and the matrix phases. As a key feature of microstructure, the morphology of the coherent particles is essential for understanding the second-phase strengthening eff ect in various industrial alloys. This letter reports anisotropic growth of coherent ferrite from austenite matrix in pure iron based on molecular dynamics simulation. We found that the ferrite grain tends to grow into an elongated plate-like shape, independent of its initial confi guration. The fi nal shape of the ferrite is closely related to the misfi t between the two phases, with the longest direction and the broad facet of the plate being, respectively, consistent with the best matching direction and the best matching plane calculated via the Burgers vector content(BVC) method. The strain energy calculation in the framework of Eshelby's inclusion theory verifi es that the simulated orientation of the coherent ferrite is energetically favorable. It is anticipated that the BVC method will be applicable in analysis of anisotropic growth and morphology of coherent second phase in other phase transformation systems.     

A STUDY OF TEMPERATURE-DEPENDENT VALENCE BOND STRUCTURE OF TITANIUM

On the basis of energy and shape method for the determination of the valence bond (VB) structures of crystal, the valence bond structure of titanium is redetermined at room temperature and calculated in the whole temperature range of 0-1943K. The outer shell electronic distribution of Ti is e_c~(2.9907) · (s_c~(0.4980) d_c~(2.4927)) ef1.0093 in crystal. The temperature dependences of the VB structures of hcp and bcc phases are the same. The VB structures of hcp and bcc phases monotonically increase or decrease with the increase in temperature, but show discontinuous changes at the phase-transformation temperature 1155K.     

Structural Optimization of Electromagnetic Swirling Flow in Nozzle of Slab Continuous Casting

During the slab continuous casting process, the flow field of molten steel in the mold plays a decisive role in the quality of the slab. In this paper, electromagnetic swirling flow in nozzle technology is proposed to control the flow field in mold.This technology can drive molten steel to rotate inside the submerged entry nozzle by electromagnetic force, thereby controlling the flow field. This research shows that it can reduce the impact of molten steel on the bottom of nozzle and partly reduce the negative pressure at the upper part of nozzle outlet which is even eliminated by optimizing the structure and angle of nozzle. The area of heat flux of the mold wall becomes larger, and the crest value of heat flux gets lower than that without swirling in nozzle and any nozzle optimization. The meniscus fluctuates smoothly, and the flow velocity at the top surface is within a reasonable range. The temperature field distribution in the mold is uniform which was beneficial to the growth of equiaxed crystal and decreased element segregation.
