【摘要】 采用文献分析法,研究物理学家江仁寿在金属液体黏滞性和表面张力方面做出的贡献.结论认为:江仁寿从19世纪30年代开始致力于液体黏滞性的研究,改进并发展了亥姆霍兹设计的双线悬挂旋转球法,利用改进的惯性棒双线悬挂球实验装置,测定了水的黏度、液态碱金属钠、钾的黏度以及钠钾合金的黏度,测得的精确数据得到国际公认并被长期沿用.江仁寿后期将研究范围拓展到液态金属表面张力方面,为中国近代流体物理学的发展做出了重要的贡献.更多还原

【Abstract】 Based on document analysis,the contribution of physicist JIANG Ren-shou to the viscousity of the liquid metal and surface tension is discussed. It is concluded that he worked on the viscosity of the liquid since the1830 s began,improved the Helmholtz double suspension spinning ball design method,used the improved suspension wire rod inertia ball experimental device to measure the viscosity of water,liquid alkali metals sodium,potassium viscosity and viscosity of sodium- potassium alloy. The measured accurate data was internationally recognized and was a long- term follow. JIANG Ren-shou expanded the scope of the study to the surface tension of the liquid metal,he has made important contributions to the development of the modern fluid physics in China.更多还原
