摘　　要：采用标准的量子力学方位阱加库伦位垒,计算了氘 氚聚变截面。给出了0.2～280keV能区内的截面数据,与实验符合得很好。此模型说明了不可用Breit Wigner公式来讨论轻核聚变反应。将此模型运用于束缚态带电粒子之间的核反应,可以解释一系列"异常现象",并展现了开发不带强放射性的聚变能的前景。The D-T fusion cross-section is calculated using quantum mechanics with the model of square nuclear potential well and Coulomb potential barrier.The agreement between ENDF data and the theoretically calculated results is well in the range of 0.2～280keV.It shows that the application of Breit-Wigner formula is not suitable for the case of the light nuclei fusion reaction.When this model is applied to the nuclear reaction between the charged particles confined in a lattice,it explains the 'abnormal phenomena'.It implies a prospect of nuclear fusion energy without strong nuclear radiations.
