【摘要】 激光功率和抗凝素对血清的光谱影响较大 ,低功率的激光可以有效减小由血清光化学作用产生的影响 ,不加抗凝素可使特征峰明显增强。血清不加抗凝素且使用低功率的激光可以得到重现性、信噪比都较好的谱图 ,以便利用光谱法诊断疾病。更多还原

【Abstract】 The laser power and heparin have great influence on serum spectrum.The lower power laser can reduce the photochemistry reaction of serum,and the character peak in spectra of serum is enhanced without heparin.The reappearance and sign-noise ratio of laser Raman spectra of serum are better with the lower laser power and without heparin,which is a chief condition for the diagnosis of breast cancer.更多还原
