摘　　要：分别对游离态的氘 氘核系统 ,磁阱位形下的氘等离子体 ,共有电子对约束的氘 氘核系统 ,以及在晶格强力约束下实现了高密度积累的氘 氘核系统中氘核间库仑相互作用的位能曲线进行了讨论 ,并以此为基础在一维方势垒近似下研究了在上述几种约束模式下氘核对氘核的势垒贯穿 ,以及因此而引起的核反应率随相关参数的变化情况 .研究表明 ,冷聚变在物理上是说得通的 ,但聚变率太低 ,看不出有任何现实意义 .Coulomb interaction between deuterons under several restriction conditions is discussed The restriction conditions are (1) free deuteron system. (2)deuterium plasma confined by magnetic potential well. (3)two deuterons attracted by common pair of electrons. (4)deuteron system with very high density under strong restriction by lattice. Investigation on penetrating of deuteron into coulomb potential barrier of neighboring deuteron is proceeded by one dimensional rectangle potential barrier simulation under the conditions. Penetration coefficient, nuclear reaction ratio and their variation with relatively parameters are got. The results indicate: even cold fusion may be possible from physics view, but the nuclear reaction ratio is too small to have any practical significance.
