摘要
通过高感度、分析时间短、并且具有同时处理大量样品的质子激发X线放射分析法(PIXE分析法),对二叠纪和三叠纪地质层页岩中提取的微小铁粒的成分分析。发现这些微小铁粒的含量和太阳系广阔宇宙空间中铁的含量十分接近,暗示着这种微小铁粒起源于超越太阳系的广阔宇宙空间,由超新星等直接喷射到宇宙,是宇宙背景放射的物质组成部分。
The component in the micro iron particle obtained from the Permian and Triassic shale are analyzed in this paper through the PIXE analytic method, which are high sensitive, short analytic time and a large amount of proton samples inspiring X - ray disposal at the same time. It is found that the quantity of these micro iron particle is very similar to the iron quantity in the solar system universe space and this implied that this kind of micro hind the solar system and be ejected to the the materials emitted from the universe bac iron particle originate from the wide universe space beuniverse directly from a supernova and the component of kground.
