以正电子直接触发闪烁体作为起始时间信号，设计并建立了三探头符合β~＋-γ正电子寿命谱仪。谱仪时间分辨率ＦＷＨＭ＝２５５ｐｓ，并已应用到实际测量工作中。
The direct triggering of scintillator with positron is used as the starting time signal, and the three-probe coincidence β ~ + -γ positron lifetime spectrometer is designed and established. Spectrometer time resolution FWHM = 255ps, and has been applied to the actual measurement work.
