血痕时序性研究进展
Research Progress on Time Series of Blood Stain
摘要
Abstract
Blood stain is the trace evidence with the highest frequency of encountered and the richest information,and it is the key evidence needed to solve the case.By observing and analyzing the physical form and chemical characteristics of the blood stain left on the scene,investigators can partially restore the criminal process and tools,which provides an irreplaceable role for narrowing the scope of investigation and analyzing the case.The characteristics of the blood stains on different tissue carriers will change regularly with the passage of time,and even at the same exposure time,the blood stains on different carriers have different manifestations in different dilution methods and concentrations.Therefore,the detection of blood stains,the discrimination between blood stains and other body fluids,and the prediction and inference of the formation time of blood stains have always been extremely important research directions in case investigation.In this paper,the research progress of blood trace detection based on direct observation,biochemical method,optical visualization method,colorimetric quantification method and so on in recent years is reviewed,in order to provide reference for forensic practice and research.关键词
