Results: 1) The site and funds are in shortage, teachers level is limited, match quality is not high, students’ enthusiasm is hard to mobilize, parents’ concept are constrained, accidents are often happened, school corruption is difficult to control, which are the main dilemmas faced by the principal. 2) The "school football ", “gold football", "constitution football", "minor soccer" and "limbs football" are the main erroneous ideas of the principal. The following suggestions are given to the principal: upgrade idea, overall develop campus school; integrate resources to break teachers, funds and sites problems; actively propagate to reverse parents’ traditional concept; deepen the reform of football teaching according to own school; innovate rules to lead the game value return; seize the opportunity to apply for characteristic school football construction; improve the campus football security to prevent trouble before it happens; set an example, try to lead the school football activities; break system, strengthen the campus football zone construction; and prevent campus football corruption
野马追中总黄酮的测定
,
南京师范大学学报(工程技术版) , 2004,
Abstract: 采用冷浸法、加热回流法和超声法3种提取方法提取了野马追中的总黄酮,用芦丁作为对照品,硝酸铝―――亚硝酸钠紫外―――可见分光光度法测定野马追中总黄酮含量.在选定的实验条件下,芦丁的浓度和吸光度呈良好的线性关系,标准曲线的相关系数为09999,测定的相对标准偏差为127%~163%,平均回收率为9820%.该方法简便、快速、灵敏度高,并具有较好的精密度与准确度,适合中药总黄酮含量的测定.结果显示野马追中含大量黄酮类化合物,含量在2%左右;不同提取方法比较,超声法黄酮的浸出率最高
A preliminary study on DNA sequence diversity of soil microbial community affected by agricultural chemicals
农用化学品污染对土壤微生物群落DNA序列多样性影响研究

YAO Jian,

生态学报 , 2000,
Abstract: The DNA sequence diversity in four soil microbial communities affected by agricultural chemicals was evaluated by using random amplified polymorphic DNA(RAPD)fingerprints.The results showed that these soil microbial communities had differences at DNA sequence richness,diversity index and evenness.The changes in the soil microbial community diversity by agricultural chemicals were found at the DNA level.It was suggested that enrichment or loss of some microbial species may occur in the soils polluted by fert...
分子生物学方法在微生物多样性研究中的应用
杨永华,
生物多样性 , 2000,
Abstract: ?微生物多样性是生物多样性的重要组成部分。由于微生物和大生物(动、植物)相比,存在着多种显著差异,因此其多样性研究、保护及利用也有所不同,尤其是研究方法亟待完善、提高。近年来,分子生物学方法广泛用于微生物多样性的研究并取得了一系列研究成果。本文从四个方面加以介绍:1)微生物总dna制备及其遗传多样性检测方法;2)16srrna基因序列研究;3)核酸杂交分析技术;4)dna动力学的研究。今后的发展趋势是加强这些方法间及其与传统方法的有机结合,并发展新的方法,促进微生物多样性研究的深入开展。

,贾桂华
图书情报工作 , 1997,
Abstract: ?“情报”一词多义的术语观违背了科学术语的专门性原则,是导致语言障碍?逻辑荒谬和学术思想混乱之源?只有坚持术语专门性的科学观,才能克服实际工作中的障碍,健全和发展信息科学。
“情报学”亦应更名——与邱均平先生商榷
,黄炳坤
图书情报工作 , 1994,
Abstract: ?中文“情报”有传统概念与非传统概念之区别。非传统概念“情报”实为“信息”之误称,应更正为“信息”;而传统概念情报,没有误称问题,不能乱改。“情报学”因其研究的“情报”属非传统概念,当然要改。

Abstract: 摘要:为实现地方高校体育院系在“地方高校转型发展战略”和“全民健身国家战略”两个重要机遇期,更好的调整办学定位,优化服务职能,彰显独有价值,助力强国建设,运用文献资料调研、专家访谈和实地考察法对地方高校体育院系服务区域发展进行研究,结果显示:1)地方高校体育院系急需向主动、直接服务型高校转型升级,且具有地域和文化、办学成本和社会资本、人力和场馆资源、区域体育资本市场信息获取等优势;2)转型升级存在办学定位错位,专业设置趋同,服务意识薄弱;现代化大学治理体系建设滞后,服务动力不足;师资、办学资源配置结构失衡,服务能力不强;服务体制机制缺失,服务运行不畅等困境。提出服务观念、服务对象、服务内容、服务体制、机制和评价等转型升级策略,为地方体育院系更好的服务区域提供理论和实践参考,为教育主管部门对其社会服务能力综合评估提供决策建议。
Abstract: The purpose of this study was to help local college’s sports department to adjust education orientation, optimize service function, show special value, and assist nation construction in “local colleges’ transformation strategy” and “nationwide fitness strategy”. This paper analyzed local colleges’ sports department service area development by the methods of literature review, expert interview, and field investigation. Results: 1) The upgrading of local colleges’ sports department needs changing to initiative and direct service college. Local colleges have advantages in region and culture, educational cost and social capital, manpower and facility resources, regional sports capital market information acquisition. 2) The existed problems of transformation and upgrading are wrong education orientation, similar major setting, weak service conscious, lagged modern university running system construction, unbalance of faculty and other resources structure, deficit service mechanism, and unsmooth service running. We put forward a transformation and upgrading strategy, including service concept, service object, service content, service system, mechanism, and evaluation, for local college s’ sports department and their service area theory and practice. And we hope it will provide a new angle to comprehensively evaluate their social service ability for government education administrative section
纺锤体检验点的功能与染色体不稳定性
,郑宇鹏,雪彪
科学通报 , 2002,
Abstract: 细胞生长和个体发育均依赖于母细胞将遗传物质(染色体)精确地分配给两个子细胞。在染色体分离过程中,纺锤体检验点起到了举足轻重的作用。染色体的正确分离是遗传信息稳定性的保证,而异常分离则产生染色体不稳定性,继而直接或间接地导致了一些疾病的发生,如先天愚型综合症和癌症等。动粒及其调控蛋白构成了纺锤体检验点,决定细胞有丝分裂过程中染色体分离的时空可调性。
