摘　　要：介绍了第19次中国南极科学考察中海冰走航和定点调查使用的一些新技术.实践发现这些辅助技术可以提高裸眼观测的准确性,它们同样可以应用于渤海海冰和内陆河冰的现场调查.其中可视技术、船舶雷达跟踪技术和冰层厚度变化过程测试技术应用前景宽阔,介绍了它们的测试目标、原理、组成和运行性能.Some new techniques are introduced in this paper, which were used in the route and field sea ice investigation during the 19th Chinese Antarctic Expedition. The practice has found that these techniques made the observation more accurate, and they can be used in the sea ice investigation in the Bohai Sea and inland river ice. The techniques of video, marine radar for icebergs movement and ice sheet thickness are more useful. Their designed aim, principles, components and capabilities are given.
