裂变径迹方法是近十多年内发展起来的新技术,目前它正广泛应用于各个学科领域,因而引起许多科学家的重视和关注。1974年美国首次建立了裂变径迹玻璃系列。至今,世界各国的径迹实验室均向美国购买这种标准玻璃,由于价格很贵加上不便购买,这就给径迹工作的开展带来了很多困难。美国目前使用的主要是标准铀玻璃,其铀含量分别为:SRM
Fission track method is a new technology developed in recent ten years. At present, it is widely used in various disciplines and thus attracts many scientists’ attention and attention. In 1974 the United States for the first time established a series of fission track glass. So far, all the track laboratories in the world have purchased such standard glass from the United States. Due to the high price and the inconvenience to purchase, this has brought many difficulties to the track track work. Currently, the United States mainly uses standard uranium glass with uranium contents of SRM respectively
