重离子核反应 meaning in English

heavy ion induced nuclear reaction
heavy ion nuclear reaction

The isospin effect and k production in intermediate and high energy heavy ion collisions ( hics ) are hot topics in the nuclear physics . based on the isospin - dependent quantum molecular dyanmics ( iqmd ) model and self - consistent relativistic boltzmann - uehling - uhlenbeck ( rbuu ) model , we have studied them and obtained some interesting results . as for the study of isospin in intermediate energy hics , we ' ve investigated how both stength ( q ) and density dependence of symmetry potential ( sp ) affect many measurable observables , such as the yield , phase - space , and isospin distributions of fragments , as well as the correlations between intermediate - mass - fragment ( imf ) multiplicity n and charged - particle multiplicity n , , light - charged - particle ( lcp ) multiplicity n , and neutron multiplicity n ,
在中能重离子碰撞的同位旋研究方面，分别研究了对称势的强度( c _ s )和其密度依赖形式对中能重离子核反应各类碎片产物产额、相空间、及其同位旋的分布，中等质量碎片多重数( n _ ( imf ) )与带电粒子多重数( n _ c ) 、轻带电粒子多重数( n _ k ) 、中子多重数( n _ n )的关联等多种实验观测量的影响，以获取对称势中该两方面的信息，尤其着重于研究如何分别获取有关该两方面的信息的途径。
