摘　　要： 用新型快速显微多道分光光度(MMSP)技术,在生理环境(pH、温度、氧分压和渗透压)改变下,对单个活态人血红细胞内血红蛋白分子的吸收光谱进行监测。发现生理环境的改变,引起血红蛋白吸收光谱曲线540,575nm特征吸收峰的峰高、峰位和峰形发生了不同程度的变化。MMSP技术提示血红蛋白分子的结构、浓度和功能与上述生理环境密切相关。 With the application of a novel fast multi-channel micro-spectrophotometry（MMSP）, the absorption spectrum of intracellular hemoglobin molecule in a human single living red blood cell was monitored under the altered physiological environments （pH, temperature, partial pressure of oxygen, and osmotic pressure）. It was found that on the absorption spectrum curve of hemoglobin the spike, the height and the position of the characteristic absorption peaks at 540 and 575nm were altered obviously with the changes in physiological conditions, indicating that the concentration, structure and function of the hemoglobin in the red blood cell may be closely associated with the physiological environments.
