摘要
运用因子分析法对青海湖区牦牛体内内脏微量元素含量进行综合评价.提取了三个主因子,并对主因子做出了合理的解释.
The factor analysis is applied to trace element evalution of yak internals in Qinghai Lake Area. Based on the correlation matrix of the data sets, a three-factor model of yak internals in Qinghai Lake Area is extracted to interpret the trace elemental characteristics of yak internals.
