马克思、恩格斯关于科学技术对于经济促进作用的认识     

赵峰 《和田师范专科学校学报》2011,30(1):21-22

马克思早在‘资本论》（第一卷）中就曾经谈到过“科学技术是生产力”,第一次工业革命之后的事实也证明了这一论断的正确性,科学技术对于经济的促进作用非常巨大。邓小平同志将这一论断上升为“科学技术是第一生产力”,这对于中国的经济发展尤其具有重要意义。  相似文献

石门坎苗族文化在短时间内从边缘崛起到繁荣引起众多关注,本文从石门坎的历史叙述着手,探究石门坎文化现象背后的驱动力,发现饱受压迫的苗族的政治诉求以及强烈的族群意识是产生这次苗族文化繁荣的主要动力。  相似文献   

球墨铸铁等温淬火前后切削加工性能研究     

李专洋 《新课程学习(社会综合)》2011,(11)

球墨铸铁等温淬火后力学性能大大增强,但切削加工性随之变差。分析热处理后材料微观组织的变化,并采用晶体压电传感测力仪、电荷放大器及计算机组成的切削力数据采集系统测量陶瓷刀具干切削球墨铸铁（DI）及等温淬火处理后的球墨铸铁（ADI）时的切削力。比较不同切削深度、进给速度及切削速度下,DI和ADI两者之间切削力大小关系,观察两者切屑形态的异同,研究球墨铸铁等温淬火前后切削加工性能的变化。结果表明,等温淬火后随着金相组织的转变,材料力学性能大幅增强,切削力大幅增加,切屑短小崩碎．易飞溅,切削加工性能明显变差。  相似文献   

狭义相对论中各变换式的重新推导及合理性分析   总被引：1，自引：0，他引：1  

田树勤 《廊坊师范学院学报(自然科学版)》2011,11(4):51-55

鉴于狭义相对论的不自恰性,对整个理论体系存在的两处失误进行了修正,使之在符合现有实验的基础上,与经典理论达到融合。首先指出导出洛仑兹时空变换式的原始数学模型存在缺陷,对其修正后,重新推导出了新的洛仑兹时空变换式。其次对力的定义进行了严格分析,据此导出两惯性系间的力变换式,简洁明了。对比新旧变换式(推论),阐述了旧变换式存在的不合理之处和新变换式的合理性。  相似文献   

对范德瓦耳斯气体引力势能的一种谬论的深入分析     

邵云 《咸阳师范学院学报》2011,26(6):32-35

对范德瓦耳斯气体引力势能理解中的一种错误进行深入分析,根据统计的思想,用两种方法证明了范氏气体摩尔引力势能的表达式,并指出它的适用条件是短程弱引力分子气体;通过对比范氏固体和范氏气体引力势能的计算过程,揭示了谬论的错误所在;从概率论的角度分析了膨胀时气体引力势能变化量有别于固体的根本原因。  相似文献   

Integrating the theory of planned behavior and behavioral attitudes to explore texting among young drivers in the US     

《International Journal of Information Management》2020

The proliferation of cell phones and the growing culture of constant connectivity has introduced a plethora of new challenges for mobile citizens. One of the major challenges transportation professionals desire to address involves the use of cell phones to text while driving, especially for less experienced drivers. In this study, the Theory of Planned Behavior (TPB) in conjunction with psycho-social factors is utilized to explore the intention to text while driving among young drivers. The results of a survey administered to 524 drivers suggest that the TPB constructs (attitude, subjective norm, and perceived behavioral control) along with the perceived disadvantages of abstention and age of the driver explain a significant amount of variance in the intention to send text messages while driving (adjusted R² = 0.71).  相似文献   

“十二五”以来科学基金资助项目增长驱动分析     

徐哲  周凌云  唐湘方 《科研管理》2020,41(2):283-288

 Institute of Animal Science, Chinese Academy of Agricultural Sciences was established in 1957 and it is a national multi-discipline research organization in the field of animal sciences. The Institute of Animal Science, Chinese Academy of Agricultural Sciences sets up 5 research departments, namely: Animal Nutrition and Feed Science, Animal Biotechnology and Reproduction, Animal Germplasm Resources and Production, Grassland Science and Veterinary Medicine as well as a central laboratory for chemical analysis. Institute of Animal Science, Chinese Academy of Agricultural Sciences carries out applied and fundamental research and technical development and research with swine, poultry, cattle, sheep and goats as main research objectives. The institute puts emphasis on the areas of germplasm resources, genetics and breeding, reproduction, feed science, nutrition and animal bio-technology, veterinary medicine, in order to solve the scientific and technical problems in animal production which are crucial, basic, commonly encountered or orientation-determining for the animal production. Moreover it is also engaged in organizing and coordinating key national research projects, extension of research achievements and advanced techniques, training of high-ranking scientists and technicians, promotion of domestic and international scientific exchange and collaboration.  The National Natural Science Foundation of China(NSFC) plays an important role in promoting the ability of undertaking national scientific and technical projects, enhancing the basic research and independent innovation, supporting the industrial development, training research teams and extending the international academic influence for the Institute of Animal Sciences of the Chinese Academy of Agricultural Sciences.  Based on the summary and analysis of the number of applications and projects funded by NSFC, the funded rate and the distribution of disciplines and fields since the implementation of the 12th Five-Year Plan from the Institute of Animal Science, Chinese Academy of Agricultural Sciences, we analyzed the overall development trend and the major driving factors of the growth on projects supported by NSFC from Institute of Animal Science, Chinese Academy of Agricultural Sciences in three aspects. They are the macro level of the State, the medium level of the institute and the micro-level of NSFC′s delicacy management. Besides, we summarize the refined managerial experience of the institute′s projects funded by NSFC, propagate the culture of NSFC and build up the mechanism of mobilization and examination. Furthermore, based on the gap of the National Natural Science Foundation of China undertaken in our institute, we put forward some ideas about designing the strategic layout in top-level, constructing and developing the discipline and training the talent team. Meanwhile, we also take some measures to tap potential in the application of NSFC, widen application type and increase application quality. At last, we expect to further improve the management and service level of NSFC and move forward the work of NSFC into a new phase, which will provide strong scientific and intellectual support for establishing world-class agricultural research institution and innovation-oriented country.  相似文献

法律治理文化与强制力的理性构建     

景枫 《保定学院学报》2011,24(6):1-4

我们所要实现的和谐社会不是也不可能是一种完全消除矛盾的和谐社会,和谐社会也必然存在矛盾,但诸多的矛盾都能够通过合理的方式加以化解。国家强制力的理性构建必须明确这样的基本理念,才可能真正促进优良的法律治理文化的形成,让我们的社会变得更加和谐美好。  相似文献
