摘要
本文应用流体力学中L.Rayleigh分析法和Buckingham的π定律来估算岩浆活动中一个重要的动力参数——岩浆上升速度,以期避开岩浆究竟属牛顿流体还是非牛顿流体这一尚存争议的问题。作为初步尝试,此法在研究岩浆活动的各种动力参数时是值得重视的。
A new approach to the estimation of ascending velocity of magmas has been proposed M avoid dealing with a difficult unsolved problem that magmas are Newton fluids or nen-Newton fluids. L. Rayleigh's analysing method was employed in the estimation of the ending velocity which was considered as a function of viscosity of magma, diameter of carried by the magma and density difference between magma and nodules, whereas a law developed by Buckingham was used to calculate the ascending velocity when it was to be a function of pressure difference between two ends of ascending vent of
