【摘要】 <正> 铁污染是大气污染中较为常见的一类。虽然人们常用滤纸收集然后用化学方法分析,但本文提出用穆斯堡尔谱学这一核方法来分析悬铃木上的绿斑,可以准确了解铁污染的分布,而且不仅可以定量,还可以了解污染物的化学结构,甚至铁颗粒尺寸的大体分布,方法简便。更多还原

【Abstract】 The Fe-57 Mossbauer effect was used for analyzing the green-stains on the barks of plane-trees. It can be successfully used for determining the degree of the iron pollution and obtaining some information on the microstructure of the pollutants. It was also possible to apply the effect in the investigations of iron concentration variations due to nuclear explosions made in the atmosphere.更多还原
