1) Lead absorption
铅吸收
1.
A patient with dermatomyositis accompanying lead absorption was reported, whose illness broke out constantly.

4) lead recovery
铅回收
5) recovery of scrap lead
废铅回收
1.
By way of analysis on the course of life cycle of lead, the following causative factors of recovery of scrap lead are found, such as domeslic consumption rate of lead products, recovered lead consumption rate, amortized scrap lead recovery.
它们是:铅品的国内消费率、可回收性铅消费率、折旧废铅回收率等。

分子式：
CAS号：
性质：238U和235U两个母体铀同位素的特性实质相同，所产生的放射性成因206,207Pb的方程可合并为（207Pb/206Pb）=[(235U/238U)]（t-1）。235U/238U现在的比值是1/137.8，利用非放射性成因‘稳定’204Pb作为参考同位素，作（207Pb/204Pb）与（206Pb/204Pb）的Pb-Pb等时线，应用方程计算年龄，式中（207Pb/204Pb）和(206Pb/204Pb)0是初始比值。
