电提取离子法中离子运移机理初探

首先讨论了大量离子系统的初值问题，随后介绍了６个基本概念，估算了地层中离子的平均热运动速度。导出了离子散射的指数规律，得出离子的平均自由时间的数值等于散射几率的倒数；离子的平均漂移速度和电场强度成正比，离子淌度与平均自由时间成正比，与有效质量成反比；介质的电导率和离子浓度、平均自由时间成正比，与有效质量成反比的结论有有关公式、表达式。指出了离子的运移机理是，运移－散射－再运移－再散射，直到离子被吸

DISCUSSION ON IONIC MIGRATION MECHANISM BY ELECTRIC EXTRACTING ION METHOD

First of all, the initial value of vast amount of ion is discussed and six basic concepts are introduced. Then the average thermal kinematic velocity of ion in the stratum is estimated. The index law of ion scattering is deduced. The value of average ionic freedom time is equal to the reciprocal of scattering probability. The average drifting velocity of ion is directly proportional to the electric field intensity. The ion mobility is directly proportional to its average freedom time and inversely proportional to efficient quality. The medium conductivity is directly proportional to ion density and average freedom time while inversely proportional to efficient quality. The paper lists out some related formulas and points out that the migration mechanism of ion is migration scattering remigration rescattering untill the ion is absorbed.
