中文摘要：
快微团簇穿过固体时和固体发生相互作用过程中，尾流效应是一个显著的特性．但由不同元素或原子构成的异构微团簇和固体作用分解后，其较重离子的能谱往往很难观察到尾流现象，这是一个倍感困惑的实验现象．本文系统研究了异构微团簇库仑爆炸中较重离子尾流效应表现不明显甚至’消失’的缘由．通过理论推算结合实验过程以及与实验条件等的综合研究，论证出分辨因素、计数差因数和作用力因素是造成这种反常现象的主要原因，给出了完整的分析．并以HD’、HD＋等离子为例，对库仑爆炸实验中异构微团簇在以上三个因素方面的产物采样、发散等过程做了较详细论述和说明．将对以后从事该领域的研究工作具有借鉴和参考意义．
英文摘要：
The wake effect is a significant feature in the interaction between fast Micro-clusters and solid. However, in decomposition of isomerism micro-clusters （different elements or atoms）, its heavy-ion energy spectrum is often difficult to observe the phenomenon of wake turbulence, which is a particularly embarrassing experimental phenomena. This systematic study of heavy ion wake effects of the isomerism micro-cluster from the Coulomb explosion try to give the explanation on this. Through theoretical calculations and experiments demonstrate, we found the resolution ratio, the counting factor and the forces on the fragments are the main reason for this anomaly. The conclusion will be helpful in the future research in this field.
