Multipolar model for collisional quantum interference on rotational energy transfer

A theoretical model of collisional quantum interference ( CQI) is developed in a diatom-diatom system based on the first-order Born approximation of time-dependent perturbation theory and the multipolar interaction potential. The transition cross section is obtained. The relations between the differential and integral interference angles are discussed. The key factors on the determination of the differential and integral interference angles are obtained. The changing tendency of the interference angles with the experimental temperatures is obtained.     

喜马拉雅碰撞造山作用与(超)大型矿集区的形成:科学问题与思考

青藏高原及邻区是中国唯一的一块具有世界规模级的成矿富集区 ,迄今所发现的大型、超大型矿床 /矿集区 ,在时间抑或空间上均与喜马拉雅碰撞造山作用有着密切的联系 ,反映了与喜马拉雅碰撞造山作用过程相伴随的青藏高原周边及内部岩石圈薄弱地带的壳幔置换过程、层圈交换作用、流体活动及其地球化学分馏过程 ,是控制大型、超大型矿床 /矿集区形成的主要因素。青藏高原成矿大陆动力学研究是阐明该区矿产资源分布规律和进一步发现大型、超大型矿床 (矿集区 )的科学基础
