毛管内荷电粒子的移动规律与流体电阻率

当前的流体导电理论用于多孔介质时矛盾较多,不适用于研究流体电阻率和多孔介质的其他电学问题。本文认为毛管内的荷电粒子的移动过程服从水力学原则,为一层流运动,并假设毛管内液相中荷电粒子的体密度是均匀的,由力电平衡可导出毛管内荷电粒子移动速度抛物线分布规律,毛管内荷电粒子的平均速度是其最大速度的一半。毛管内的流体电流强度与毛管孔径的4次方程成反比,毛管内的流体电阻率是按抛物线的倒数分布的,其平均电阻率是最小电阻率的2倍,毛管内的电阻率是毛管孔径、离子迁移率和普通流体电阻率的综合函数,比普通流体电阻率复杂得多。

The moving law of charged Particles and the Liquid Resistivity in Capillary

This paper holds that the moving process of charged particles in capillary abides by hydrodynamics principle and it is a motion of laminar flaw; the body density of charged particles in liquid phase in capillary is approximately even, the equilibrium of mechanical force and electric force can lead up to the parabolical distribution of moving velocity of charged particals in capillary. The average velocity of charged particles in capillary is a half of its maximum. The electric intensity in capillary is inversely proportional to the fourth power of capillary diameter. The fluid resistivity in capillary distribute according to parabola's reciprocal. The average resistivity is twice its minimum. The fluid resistivity in capillarry is the comprehensive function of the capillary diameter, ion mobility and general fluid resistivity, which is much more complex than the common resistivity.
