战场生物战剂和爆炸物总有一天可被小型飞行时间质谱仪察觉，这种仪器正由约翰·霍普金斯大学应用物理实验室研究人员和该校医学院研究组、马里兰大学以合作方式发展。飞行时间质谱术的意思是，样品分子被所加电压而电离并加速达到一理想的动能，然后解除电压漂移已知距离，到 One day a battlefield biological warfare agent and explosive can be spotted by a small time of flight mass spectrometer, which is being used by researchers at Johns Hopkins University’s Applied Physics Laboratory and the School’s Medical School Research Group, University of Maryland, development of. Time-of-flight mass spectrometry means that the sample molecules are ionized by the applied voltage and accelerated to an ideal kinetic energy and then relieved of the voltage drift by a known distance to
