利用伴随粒子飞行时间方法，通过测量１４．７ＭｅＶ中子在聚乙烯和碳样品上的次级中子谱，得到了在０．９９—１４．７ＭｅＶ能量范围内ＳＴ－４５１液体闪烁体中子探测器的探测效率值，其总误差＜４．７％，其中统计误差＜３．５％．
The secondary neutron spectra of 14.7MeV neutrons on polyethylene and carbon samples were measured using the accompanying particle-based time-of-flight method. The neutron detection of ST-451 liquid scintillator at energies between 0.99 and 14.7MeV The detection efficiency of the device, the total error <4.7%, of which the statistical error <3.5%.
