【摘要】 新近沉积土的众多变量特征,可以近似的用4个主成分因子来代替。虽然因子数量简化成了4个,但是其中蕴涵的特征信息量却高达94.989%,损失的信息相当少,几乎可以忽略不计,而且这4个主成分因子之间所包涵的信息互不重叠,这就大大的降低了分析问题的复杂性。
【Abstract】 By factor analysis, we extracted four comprehensive factors that can represent the characteristics of therecently deposited soil. The characteristic information included in these four comprehensive factors reach 94.989%and only little information lost. All these information is not overlap, so it will reduce the complexity when analyzingproblem.
