U自发裂变径迹最大投影长度研究矿物蚀刻灵敏度的方法,有效地解决了矿物蚀刻条件的选择问题。利用该法成功地确定了国际标准年龄样品——美国鱼谷凝灰岩中磷灰石的三种蚀刻条件下的灵敏度.
A method for studying etching sensitivity of mineral tracks by measuring maximum projected lengths of spontaneous fission tracks from

U is reported. This method can effectively solve the problems of selecting etching conditions of minerals. The etching sensitivities under three etching conditions for apatite from the Fish Canyon Tuff of Southwestern Colorado
USA were measured successfully.
