大力弘扬仲恺精神,办人民满意的大学

仲恺精神是中国革命近代史留给中华民族精神财富中之瑰宝,是仲恺农业技术学院80年的办学历程中逐步形成的,经由一代代师生的努力,而逐渐积累起来的仲恺文化之精髓.仲恺精神是一种赤诚的爱国精神、坚定的革命精神和顽强拼搏的实干精神.传承革命先辈的伟大精神是纪念大学的历史使命,是建立学校价值取向、行为准则、育人环境、学人品格的基础.     

How to make water run uphill

A surface having a spatial gradient in its surface free energy was capable of causing drops of water placed on it to move uphill. This motion was the result of an imbalance in the forces due to surface tension acting on the liquid-solid contact line on the two opposite sides ("uphill" or "downhill") of the drop. The required gradient in surface free energy was generated on the surface of a polished silicon wafer by exposing it to the diffusing front of a vapor of decyltrichlorosilane, Cl(3)Si(CH(2))(9)CH(3). The resulting surface displayed a gradient of hydrophobicity (with the contact angle of water changing from 97 degrees to 25 degrees ) over a distance of 1 centimeter. When the wafer was tilted from the horizontal plane by 15 degrees , with the hydrophobic end lower than the hydrophilic, and a drop of water (1 to 2 microliters) was placed at the hydrophobic end, the drop moved toward the hydrophilic end with an average velocity of approximately 1 to 2 millimeters per second. In order for the drop to move, the hysteresis in contact angle on the surface had to be low (相似文献   

“双师型”师资队伍建设与高职高专特色办学

"双师型"教师在知识能力方面不仅应具备本专业扎实的理论知识和丰富的教学经验,而且具有较强的解决本专业技术问题的能力。加快"双师型"师资队伍建设步伐是实现高职高专特色办学的重要途径。加强高职高专"双师型"师资队伍建设,应引进与在岗培训相结合,适当扩大兼职教师比例。     

Ecology. Pacific salmon run hot and cold

Using a novel technique, described on page 795, paleoceanographers have been able to chart the abundance of sockeye salmon in the Bristol Bay and Kodiak Island regions of Alaska over the past 300 years--by far the most complete record yet. Through time, they found, sockeye populations have alternately soared and slipped, following natural climate variations--well before commercial fishers began throwing nets over the sides of boats.     

团结务实开拓创新努力办好农业广播电视教育

津南区农广校开展多层次、多形式、多渠道的学历教育和技术培训，主要方法是：一在全市首家加挂“津南区农民科技教育培训中心”的牌子，全面承担政府对农民实施科技教育培训职能；二是加强队伍建设，提高管理水平。三是承担“跨世纪青年农民科技培训工程”项目，措施得当、效果突出。同时紧紧抓住产业结构调整及农民需要这条主线，采用技术推动模式、政策推动模式、园区推动模式、示范户推动模式和信息推动模式等5种培训模式，以点带面，有效地促进了“培训”工作的深入开展。
