, furthermore, these clusters in that case tend to contract due to the decrease of relevant atomic radius and the co-ordination number. This kind of liquid-phase structure leads to a more homogeneous Cu-rich...: electric pulse modification; Al-Cu melt; atomic cluster; liquid structure 1 Introduction With the rapid development of solidification technology and cluster physics, the effects of melt structure......
of nanomaterials. Single particle-inductively coupled plasma mass spectrometry (SP-ICP-MS) was investigated to detect the size of gold nanoparticles (AuNPs) in this work. Discrimination of particle signal and iterative algorithm were used to calculate the baseline of particle signal. Influence of dwell time was discussed and 3 ms was selected as dwell time for size detection. Different AuNPs......
. Then the simulation sample size could be determined according to the estimation of parameters and required precisions. There are primarily two types of performance measures for stochastic simulation systems: (1...Determining simulation sample size for given precision requirements SHI Peng(时蓬), YANG Ming(杨明) (Control and Simulation Centre, Harbin Institute of Technology, Harbin 150080, China) Abstract......
