摘要
用氮分子激光作光源,以激光诱导荧光光谱方法测定体外人工血栓的荧光光谱。实验显示血栓荧光光谱具有不同于动脉内膜和斑块荧光光谱的三个特征:1.荧光强度普遍减弱.2.420nm前无荧光峰.3.荧光峰值波长向较长波长移位。
We used laser induced fluorescence spectroscopic method with N_2 laser at the wa-velength of 337 nm as an excitation scouce to differentiate atherosclerotic plaques from normaltissues. The ratio between fluorescence intensities at the wavelength of 390 nm and 476 nm waschosen as a dimesionless contrast function. The ratio values for the plaques were usually largerthan 1.25, but the normal tissues were smaller than 1.25.
