平均平方误差 - Abstract : the effects of the impurity particles on the structure of a 2d dusty plasma system . the mean square displacement , pair correlation function have been calculated to analyze the system ' s structure characteristics . the results show that both of the impurity particles ' content and mass or charge in the range of our caleulation will decelerate the system ' s phase transition process . here the impurity particles are smaller than the background dusty particles on mass and charge
文摘:利用分子动力学模拟研究了杂质粒子对二维尘埃等离子体系统的影响.分别计算了平均平方位移,两体相关函数来分析系统的机构特性.结果表明,在参数范围内,杂质的含量以及杂质的质量和电荷的大小都会减慢系统的相变.杂质粒子在质量和电荷上都小于背景的尘埃粒子 - Aimed at the parameter estimation and model reduction problems of non - linear systems in noisy environment , a class of particle swami optimization ( pso ) approach with hypothesis test is proposed , named psoht , which estimates parameters by using pso operator in conjunction with evaluation and comparison in statistical sense to minimize mean square error function
