20世纪20年代末中国初中混合数学教科书考察     

陈婷 《教育学报》2010,6(2)

受欧美,尤其是美国数学教育倡导融合主义主张的影响,20 世纪20年代我国编写的初中混合数学教科书数形结合,各科知识前后衔接关联自然.但由于编写过程中打乱了学科知识本身的系统性,对数学的"整体性"考虑不够,勉强把几种知识混合为一体,学生难以学到系统的知识,再加之师资水平有限,编写队伍不够成熟,以及当时毕业会考的影响等原因,混合数学教科书以失败而告终,但这次实验对当时及后来我国中学数学教学产生了深远的影响.  相似文献   

战争影响下的民生——北宋经略西北的另一面     

封婷 《金陵科技学院学报(社会科学版)》2010,24(4)

北宋西北地区因其军事地理位置的特殊性,受到统治者的高度重视.北宋经略西北,战争频繁,对宋夏边境蕃族人口的发展有严重影响;战争及运粮过程中北宋兵力与民力的损伤也极其严重;北宋民众的劳役负担逐渐加重,沿边居民的生活亦受到影响.战争影响下的民生是认识北宋经略西北历史的重要内容.  相似文献   

Development of a large-scale isolation chamber system for the safe and humane care of medium-sized laboratory animals harboring infectious diseases

The close phylogenetic relationship between humans and non-human primates makes non-human primates an irreplaceable model for the study of human infectious diseases. In this study, we describe the development of a large-scale automatic multi-functional isolation chamber for use with medium-sized laboratory animals carrying infectious diseases. The isolation chamber, including the transfer chain, disinfection chain, negative air pressure isolation system, animal welfare system, and the automated system, is designed to meet all biological safety standards. To create an internal chamber environment that is completely isolated from the exterior, variable frequency drive blowers are used in the air-intake and air-exhaust system, precisely controlling the filtered air flow and providing an air-barrier protection. A double door transfer port is used to transfer material between the interior of the isolation chamber and the outside. A peracetic acid sterilizer and its associated pipeline allow for complete disinfection of the isolation chamber. All of the isolation chamber parameters can be automatically controlled by a programmable computerized menu, allowing for work with different animals in different-sized cages depending on the research project. The large-scale multi-functional isolation chamber provides a useful and safe system for working with infectious medium-sized laboratory animals in high-level bio-safety laboratories.  相似文献   

Personalized image-based templates for precise acetabular prosthesis placement in total hip arthroplasty: a pilot study     

Bin Chen  Sheng-xiang Xiao  Peng-cheng Gu  Xiang-jin Lin 《Journal of Zhejiang University. Science. B》2010,11(9):673-680

Objective:In order to achieve accurate implantation of the acetabular prosthesis in total hip arthroplasty(THA),we designed individual templates based on a three-dimensional(3D) model generated from computed tomography(CT) scans.Methods:Individual templates were designed for 12 patients who underwent THA.A physical template was designed to conform to the contours of the patient's acetabulum and to confirm the rotation of the acetabular center.This guided the acetabular component orientation.Results:The preoperative and postoperative X-ray and CT scans were obtained to assess the location with respect to the accuracy of the acetabular component.For all patients,the abduction angle of the acetabular component was 46.7°o 54.3°and the anteversion angle was 11.3°to 18.5°.Conclusions:The assessment of postoperative CT scans demonstrated higher accuracy of the acetabular component bore when used with the individual template.Therefore,the individual template can be an alternative to the computer-assisted navigation systems,with a good cost-performance ratio.  相似文献   

Preparation of high-affinity rabbit monoclonal antibodies for ciprofloxacin and development of an indirect competitive ELISA for residues in milk   总被引：2，自引：0，他引：2  

Bin Huang  Yun Yin  Lei Lu  Hai Ding  Lin Wang  Ting Yu  Jia-jin Zhu  Xiao-dong Zheng  Yan-zhen Zhang 《Journal of Zhejiang University. Science. B》2010,11(10):812-818

A convenient competitive enzyme-linked immunosorbent assay (ELISA) for ciprofloxacin (CPFX) was developed by using rabbit monoclonal antibodies (RabMAbs) against a hapten-protein conjugate of CPFX-bovine serum albumin (BSA). The indirect competitive ELISA of CPFX had a concentration at 50% inhibition (IC₅₀) of 1.47 ng/ml and a limit of detection (LOD) of 0.095 ng/ml. The mAb exhibited some cross-reactivity, however, not so high with enrofloxacin (28.8%), ofloxacin (13.1%), norfloxacin (11.0%), fleroxacin (22.6%), and pefloxacin (20.4%). And it showed almost no cross-reactivity with other antibiotics or sulfonamides evaluated in this study. The competitive ELISA kit developed here could be used as a screening tool to detect and control illegal addition of CPFX in food products. This kit had been applied to milk detection and the recovery rates from samples spiked by CPFX were in a range of 63.02%–84.60%, with coefficients of variation of less than 12.2%.  相似文献

历史事实与文本情境:人类学田野复原非洲本真态     

马燕坤  屠潇 《邯郸学院学报》2010,20(1):108-113

非洲具有丰富而悠久的历史文化,其独到的表述方式和记忆脉络传递着非洲古老的文化内涵。而在近现代进程中,随着科学技术、理性认知引发的人类文明登上时代的顶峰,非洲的这一特色遭遇了前所未有的挑战。来自外界,尤其是西方的霸权试图抹去并替代非洲的传统。结果造成非洲声音被压抑,形象遭扭曲的局面。人类学田野作为一种可行而科学的方法,在充分彰显非洲历史文化风貌并促成非洲与外界形成对话的同时,能够较好地剥离掉西方在表述非洲时附上的情境因素,从而复原非洲本真态。  相似文献   

高等职业教育“校企合作”模式的探讨   总被引：2，自引：0，他引：2  

叶潇  曾青松 《中国科教创新导刊》2010,(11):54-54,56

＂校企合作＂是高等职业教育发展的必然选择。高职院校与企业的合作有助于提高教师的教学水平和科研水平,有助于教师了解企业的需求,培养满足市场需求的人才,有助于学校为满足市场需求和经济发展而进行的教学改革,有助于实现教育对象从学生到从业者的＂角色转换＂。我国高职教育校企合作现状较流于表面,校企合作实施过程中存在体制及认知的障碍,校企合作模式可行性的实践方案应该紧密联系企业,建立＂服务外包＂机制,实施＂工学交替＂。  相似文献   

健全转学机制,促进教育公平——读《高等教育不能回避历史——21世纪的问题》     

李化树  付婷 《安阳工学院学报》2010,9(4):97-99

《高等教育不能回避历史——21世纪的问题》是克拉克·克尔博士所著高等教育文集的第三卷。在第三编"高等教育机构职能的分化和均质化"中,作者深入分析了21世纪的高等教育趋同模式——既普遍入学又促进优秀。作者认为精英教育必须保持高度的选择性,以尽力维持精英型大学的水准,有必要建立一种能有效促使高等教育系统功能分化的制度,这对保持我国大学的精英性具有重要的理论意义和实践价值。  相似文献
