【摘要】 本文应用光声光谱技术,检测正常人和泌尿系肿瘤病人的尿光声光谱图.结果:正常尿光声光谱图中,于240、290nm^±2～3波长处各有一上升的波峰;红、白细胞异常尿液的谱线上,除有正常尿的2波峰外,在410nm^±2～3波长处,又增加一个特征性波峰;肿瘤病人的尿,于240、275、330nm^±2～3波长处,各有一个特征性波峰。肿瘤者尿液中混有红、白细胞的,则于240、275、330、410nm^±2～3波长处各有一个特征性的波峰.并对其机制作了讨论。更多还原

【Abstract】 This report discusses the application of PAS technique that is used to detect the urineof normal and cancerous patients.From the 85 cases investigated,it is found that in normalspectrum,there are two absorption peaks in 240nm,290nm^±2～3,respectively.In additionto these two peaks,there is another charactristic peak at the wavelength of 410nm^±2～3inthe spectrums of inflammatory urine.The PAS spectrums of cancerous patients have threepeaks:240nm,275nm,330nm^±2～3.The spectrums of cancerous urine with inflammatoryhave four peaks:240nm,275nm,330nm,410nm^±2～3.The results of measurement and ap-ply them to clinical diagnosis are discussed.更多还原
