| 1 | Advances in dynamics and control of tethered satellite systems显示文摘拴住的卫星系统(TSS ) 的概念答应革命化空间探索和利用的许多方面。它提供不仅众多的可能、珍贵的应用程序,而且与他们的动力学,控制,和物理实现有关的挑战性、有趣的问题。在过去的十年,这个令人激动的话题从许多研究人员吸引了重要注意并且与动力学和控制的二个必要方面的一个焦点获得了分析、数字、试验性的成就的一个广阔数字。这篇评论文章介绍历史性的背景和最近的热话题因为空间拴住,并且以一种进步方式介绍 TSS 的动力学和控制给最先进的成就,从基本操作原则。 | Dongping P.Jin Haiyan Y.Hu | 2008 | Acta Mechanica Sinica2008，24，3： | 23 |
| 2 | Pinpointing the sources and measuring the lengths of the principal rivers of the world显示文摘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. | S.Liu P.Lu D.Liu P.Jin W.Wang | 2009 | International Journal of Digital Earth2009，2，1： | 2 |
