摘　　要：用半导体激光抽运极化１２９Ｘｅ气体，在８０ＳＹ核磁共振谱仪上单次采样得ＮＭＲ信号，信噪比大于１００，信号增强因子大于１０３，降温凝固成固态后，其信噪比大于５０，初步测得固态（约８０Ｋ）１２９Ｘｅ弛豫时间为４４００ｓ。The nuclear polarized 129 Xe gas by diode laser pumping was measured with a WP 80SY NMR spectrometer.We found that the SNR was greater than 100,and the signal enhancing factor was greater than 1000.After frozento solid state(80K),SNR was better than 50,the relaxation time was 4400s.
