介绍了由渗透方程，经理论推导得到一个滤膜渗透速率常数与氡子体~(218)Po衰变放出的α粒子脉冲计数的简单公式，设计了测量滤膜渗透速度常数的实验方法。测量结果表明，该方法的测量一致性好。

This report concludes a simple formula of the penetrating rate of filtrational membrane that is relevant to the pulse counts of α particles emitted from radon daughter of 218 Po by theoratical deduction and suggests a experiment to measure the membrance penetrating rate. Experiment results have...
