需历经“三寒四暑”的继续教育函授班学生每年都云集到师范大学参加面授,其中《地图学》是必修面授课之一.针对特殊的学习对象,结合他们具有短暂的集中时间、漫长的自学阶段、紧张的本职工作这些特点,如何让学生克服困难,顺利完成教师设计的家庭作业是检验面授效果及自学质量的关键.本人根据令教与学双方都关注的2000级地理函授班的实际做法谈些体会. 相似文献

黑龙江省测绘学会第一次会员代表大会于1965年11月22日-12月3日召开,标志着黑龙江省测绘学会正式成立。本学会是经黑龙江省社团管理部门批准成立的全省测绘科技工作者的群众性学术团体,是黑龙江省科学技术协会的组成部分,也是中国测绘学会的组成部分。黑龙江省测绘学会挂靠在黑龙江省测绘局,常设机构是黑龙江省测绘学会办公室,下设科技期刊《地理信息世界》、《测绘与空间地理信息》编辑部2个。主要开展学术交流、期刊出版、科学普及、继续教育、技术培训、科技考察、行业协调、咨询服务等工作。黑龙江省测绘学会自成立以来,已历经六届理事会。第六届理事会设立了地理信息与遥感、测绘仪器、测绘经济管理、测绘工程、测绘教育与科学普及、测绘专家咨询、《测绘与空间地理信息》编委会等7个专业委员会。目前,黑龙江省测绘学会共发展会员2210名,其中中级职称以上的科技骨干1800名。曾先后组建了鹤岗,大庆、黑河、牡丹江等地市级学会4个。1996年,经黑龙江省测绘局党组研究决定,将东北测绘情报网(黑龙江省测绘科技信息站)合并到黑龙江省测绘学会办公室,便于开展测绘信息交流等工作。黑龙江省测绘学会多年来一直被中国测绘学会评为先进集体,1992年被中国科协评为全国“学会之星”光荣称号,1991年被省科协授予“先进学会”称号。1996年被省科协评为“十五佳学会”光荣称号。2000年又在全省152个学会中再一次被评为省科协“十六佳学会”。 相似文献

Abstract Cultures throughout the world are associating with the rivers. People depend upon the rivers and their tributaries for food, water, transport, and many other aspects of their daily lives. Unfortunately, human beings have not calculated the accurate lengths for the great rivers even today. The lengths of the rivers are very different in popular textbooks, magazines, atlases and encyclopedias, etc. To accurately determine the lengths of the principal rivers of the world, the combination of satellite image analysis and field investigations to the source regions is proposed in this paper. The lengths of the Nile, Amazon, Yangtze, Mississippi, Yellow, Ob, Yenisey, Amur, Congo and Mekong, with lengths over or close to 5000 km, were calculated using the proposed method. The results may represent the most reliable and accurate lengths of the principal rivers of the world that are currently achievable. 相似文献

软科学这一术语是70年代在国外提出的.然而30多年以来,它在国外不仅未得到普遍的承认,而且对软科学的定义也还未能达成大体上一致的共识.而在改革开放后的中国,出于决策科学化和民主化的需要,经过一些领导人的提倡和支持,特别是通过1986年召开的软科学座谈会及1994年召开的全国软科学工作会议,软科学事业得到了蓬勃的发展.据初步统计,截止1998年底全国共有软科学研究机构1224个,研究人员32655人,初步形成了一支较为强大的研究队伍,并取得了数百项覆盖多个领域的研究成果,为支持各级各类的决策发挥了一定的作用. 相似文献

The very long baseline interferometry (VLBI) Intensive sessions are typically 1-h and single-baseline VLBI sessions, specifically designed to yield low-latency estimates of UT1-UTC. In this work, we investigate what accuracy is obtained from these sessions and how it can be improved. In particular, we study the modeling of the troposphere in the data analysis. The impact of including external information on the zenith wet delays (ZWD) and tropospheric gradients from GPS or numerical weather prediction models is studied. Additionally, we test estimating tropospheric gradients in the data analysis, which is normally not done. To evaluate the results, we compared the UT1-UTC values from the Intensives to those from simultaneous 24-h VLBI session. Furthermore, we calculated length of day (LOD) estimates using the UT1-UTC values from consecutive Intensives and compared these to the LOD estimated by GPS. We find that there is not much benefit in using external ZWD; however, including external information on the gradients improves the agreement with the reference data. If gradients are estimated in the data analysis, and appropriate constraints are applied, the WRMS difference w.r.t. UT1-UTC from 24-h sessions is reduced by 5% and the WRMS difference w.r.t. the LOD from GPS by up to 12%. The best agreement between Intensives and the reference time series is obtained when using both external gradients from GPS and additionally estimating gradients in the data analysis. 相似文献

In this letter, we are trying to resolve the electromagnetic problem for the movements of the superconducting particles of the protoplanetary cloud in the magnetic field of Saturn. The force of levitation (Meissner-Ochsenfeld phenomenon) is introduced to the field of planetary science for the first time. It is shown from our theoretical analysis that rings of Saturn might have a superconducting origin, and rings might levitate within magnetic equator plane of the planet. 相似文献
