	1	Characteristic absorption peak of the human blood measured with differential photoacoustic spectroscopy显示文摘A new highly sensitive spectroscopy technique-differential photoacoustic spectroscopy (PAS) is presented in this paper. The blood samples from 3 healthy persons, patients with leukemia, patients with pregnancy-induced hypertension (PIH), and 40 patients with nasopharyngeal carcinoma were measured by the PAS technique. The normalized, the first order, and the second order differential photo-acoustic spectroscopy of the blood were gained. The results show that ( i) weak absorption peaks or shoulder peaks, which could not be found using conventional photoacoustic spectroscopy, were determined by the first order and the second order differential photoacoustic spectroscopy which significantly improve the sensitivity of detection; and (ii) that two characteristic absorption peaks were found at the wavelength of 637 and 664 nm in all persons’ blood samples by the differential photoacoustic spectroscopy technique. This experiment concludes that the differential photoacoustic spectroscopy technique is superior	TANG Zhilie LIU Jinlong XIA Yunfei SU Yong LIANG Luisheng CHEN Gengsheng	2002	Chinese Science Bulletin2002，47，24：	2
