台湾北部海域黑潮与中尺度涡旋研究进展

The kuroshio,originating from the sea southeast of Taiwan andeast of bashi channel,is the western boundary current of the pacific and has the characterisics of strong flows,high temperature and high salinity.mesoscale eddies have strong kinetie energy with a vertical extent of 100m and a horizontal magnitude of 100km. the submarine topography northeast of Taiwan has complicated strucrures.the continental shelf region shallower than 200m occupies the western and middle part of the east china sea(ecs).in the southeastern ECS lies the deep okinawa trough,in which the main depth can reach more than 1000m.it is the geomorphological separatrix between the continental shelf and the ryukyu islands,. the kuroshio enters the ECS along the east coast of taiwen,flows northeastward along the shelf slope,and hence intrudes across the shelf break.in this paper,our concern is the interaction between the kuroshio in ECS and the taiwan strait waters on the continental shelf. meanwhile the mesoscale eddies in the north of Taiwan is another attention point.     

三类物质的接触角等温线

三类物质的接触角等温线物质溶于水后，按照它们对水的表面张力的影响，大致可分为三类，如表面张力等温线图ｌａ所示［１］。第一类是无机盐、酸和碱等物质，溶液的表面张力随浓度的增加而略有增加（曲线１）。第二类是低级醇、胺和核酸等物质，溶液的表面张力随浓度的增...     

新论生命起源

有关生命起源的“化学进化论”,笔者认为,与事实不相符合。作者根据许多事实,认为石里的低分子有机质是形成生命的主要物质来源。
