摘要: 文章介绍一种推断物证性质的方法。它利用统计学原理,能判断出两个物质一样或不一样的特征,并且给出一定的置信度。本文详细地介绍并举例说明统计量 ω(x-x_0)=sum from i=1 to N_∞(x-x_(0i))~2/(Δx_i~2+Δx_(0i)~2)在物证技术学中的应用方法。Abstract: The method to deduce the property of forensic evidence is introduced inthe paper. It can deduce whether two material evidence come from a identicalsource, and a confidence level is given. To use the statistic ω(x-x_0)=sum from i=1 to N(x_i-x_(0i))~2/△x_i~2+△x_(0i)~2in criminalistics is introduced in detail and is showed with some samples.
