    Based on Logit model, this paper develops a passenger flight choice model (PFCM) using variable precision rough set (VPRS) approach. Satisfying the required precision, this model can find out the real attributes which affect the choice of passenger on flight and the weights of these attributes without any prior information. Based on this model, the probability of passenger flight choice could be determined as a reference for airlines to design their products and improve marketing strategy.
    文章以Logit模型为基础,运用变精度粗集(Variable Precision Rough Set,VPRS)方法构建了旅客航班选择模型(Passenger Flight Choice Model,PFCM),该模型无需知道旅客航班选择数据集合以外的任何先验信息,在满足所要求精度下,即可求出旅客航班选择的真实因素及各因素权重,从而计算出某航线某时刻旅客航班选择的概率,为航空公司设计产品、改进营销提供可资借鉴的依据。
    The LODs of most elements is 1~5 ng·g-1.The concentrations of main metal impurities are in good agreement with those determined by ICP-MS,which indicate the fast analysis of high purity Tantalum without standard by GD-MS promises to be accurate.
    大多数元素的常规分析检测限在1~5 ng. g-1,主要金属杂质含量与采用ICP-MS法定量分析的结果一致,这表明GD-MS对高纯钽样品无需标样的快速分析有较高的准确度。
