飞行时间谱仪 meaning in English

time of flight spectrometer

The double differential cross section ( ddx ) of neutron emission from 51v at 10 . 26 mev neutrons was measured using normal and abnormal fast neutron tof spectrometers on hi - 13 tandem accelerator in china institute of atomic energy ( ciae ) . the problem of influence from breakup neutrons of the d ( d , n ) neutron source on secondary neutron spectra was successfully solved
用中国原子能科学研究院hi - 13串列加速器上的常规和非常规快中子飞行时间谱仪，测量了10 . 26mev中子引起~ ( 51 ) v的次级中子双微分截面，成功解决了d ( d ， n )中子源中破裂中子对次级谱的影响。
A lot of methods were used in measurement and data analysis to improve the quality of the data . the measured tof spectra were simulated by monte - carlo code streuer . the cross sections were determined by comparing the measured tof spectra with the simulated tof spectra and the data were normalized to n - p scattering measurement
本论文利用ciae发展起来的常规和非常规快中子飞行时间谱仪，利用d ( d , n ) ~ 3he中子源，测量了10 . 26mev中子引起的~ ( 51 ) v的次级中子双微分截面，成功解决了源破裂中子对次级谱的影响。
