应邀来杭参加东海及其它陆架沉积作用国际学术讨论会的日本东京大学地球物理教研室永田丰教授于4月17、18日两天在我所作学术报告,其内容为:1.东海的一般海况;2.吐噶喇海峡表面水温分布的变动和黑潮变动;3.黑湖北侧水温的微细结构;4.黑潮流轴附近浅海区地形作用的涌升;5.淡水侵入均匀旋轴盐水的特征(转盘试验);6.沿两均匀层交界面的水平淡水侵入(转盘试验)。 永田丰教授的报告内容丰富生动,图表 Professor Nagata Nagata, Faculty of Geophysics, University of Tokyo, Japan, invited to Hangzhou to participate in the international symposium on the sediment deposition in the East China Sea and other places, gave an academic report to me on April 17 and 18 two days. The contents are as follows: 1. General sea conditions in the East China Sea; 2. Changes in surface water temperature and Kuroshio in the Tugara Strait; 3. Microfacies of water temperature in the northern Black Lake; 4. Fluctuations in the terrain of the shallow sea near the Kuroshio Current axis; 5. Characteristics of freshwater invading uniform rotary shaft brine (Turntable test); 6. horizontal freshwater intrusion along two uniform layer interface (turntable test). Professor Nagata Hirota’s report is rich and vivid, the chart
