摘要 本文采用最新的观测数据,用单辐照参数化模型重新计算了12颗星,结果有8颗符合得很好,验证了单辐照参数化模型的正确性和有效性.从而为相关问题的研究提供了可靠的依据. The parameters of single neutron-exposure model are used to calculate the 12 stars in literature. The result of 8 stars fits the observation well, and the Parameters of single neutron-exposure model are proved to be correct and valid, providing reliable gist for the investigation of correlation questions.
