【Abstract】 It is a useful method for studying dinosaur by CT scan ning that proved by neutron activation analysis. According to the neutron activa tion analysis, the materials of outer and inside of dinosaur egg are showed that the environment were lands both in Xixia region Henan Province and in Ganzhou r egion Jiangxi Province in Late Cretaceous; The permeabilities of dinosaur eggshe ll are very well and the bacterium and virus are easy intruding into the dinosa ur eggs; the extinction of almost dinosaurs and the a lmost dinosaur eggs could not incubate because of the dash of falling star an d the volcanic eruption and the radioelements.更多还原
