Jian Xia · 2000
It' s traditionally believed that physical and chemical test for material evidence can only be applied to categorical authentication. The categorical and identical authentication in physical and chemical test of material evidence are just based upon the distinction of the same authentical scope of the origin (or individuality) caused by the material evidence reflector in different levels. With the development of science and technology and the increasing power for the human beings to recognize the world, physical and chemical test of material evidence is bound to the transformation from categorical authentication to identical authentication. It must be observed to combine material evidence test with the nature of the case and the detective process so as to promote to put identical authentication into practice from categorical authentication in physical and chemical test of material evidence.
