| ABSTRACT |
| The shortcomings of the present two formulae for describing column holdup are analyzed and deductions are ade to find a new formula,The column holdup,Hw,described by the new formula is dimensional,and related to soil soulte transport kinesis and column physical properties,Compared with the other two column holdups,Hw is feasible to describe dimensional column holdup during solute transport process,The relationships between Hw and retardation factor,R,in different solute transport boundary conditions are established. |
