利用光谱法检测血痕变化时序性研究

Research on the detection of temporality of blood stain changes by spectroscopy

血液中的部分化学基团会随时间发生变化。利用紫外-可见分光光度法和傅里叶红外光谱法研究人体血痕红外光谱图的时序性变化,通过分析不同时间紫外光谱图、红外光谱图中峰值的变化规律,找到血痕时序性变化的一般规律。

Some chemical groups in the blood will change with time.The temporal changes of human blood stain infrared spectrogram is studied by using ultraviolet and visible spectrophotometry and Fourier infrared spectroscopy.The general law of temporal changes of blood stain is found by analyzing the change law of peak value in ultraviolet spectrogram and infrared spectrogram at different times.
