Global optimization of Morse clusters with short-range potential is a great challenge.Here,we ap-ply our recently developed unbiased fuzzy global op-timization method to sys-tematically study Morse clusters with the potential range ρ=14 and the number of atoms N up to 400.All the putative global minima reported in the literature have been successfully reproduced with relatively high success ratios.Compared to the available results for N≤240 and several larger Morse clusters,new global minima (and local minima) with lower energies have been found out for N=164,175,188,193,194,197,239,246,260,318,and 389.Clusters with magic numbers are figured out through fitting the size-dependent global minimum energies.The cluster structures tend to be close-packed for short-range potential with large N.

In the past few years,the renormalized excitonic model (REM) approach was developed as an efficient low-scaling ab initio excited state method,which assumes the low-lying excited states of the whole system are a linear com-bination of various single monom
分析对比气相色谱–串联质谱(GC–MS/MS)法测定中药材中35种农药残留的3种样品处理方法,为中药材中农药残留检测提供参考.以乙腈为提取溶剂,样品经高速匀浆提取后,取提取液进行净化处理.比较了基于QuEChERS原则的处理方法、石墨化碳黑–氨基复合固相萃取(GCB–NH2)法和亲水亲油平衡材料固相萃取(HLB)法3种净化方式对中药材中35种农药残留检测的基质效应、色谱峰干扰、回收率等方面的影响.基于QuEChERS原则的处理方法回收率最好,除杀虫脒外其它34种农药回收率均为72.9％～110.9％,但净
