double differential meaning in Chinese

双差动

Examples

  1. The study of the effect of the momentun distribution of target nucleons on the scdw calculation is performed , which shows that the larger nucleon momentum compenents affect the double differential cross sections at backward and forward angles , while smaller nucleon momentum compenents affect the cross sections near the qes angle
    本文还分析了核子动量分布对scdw模型双微分截面计算的影响，发现大动量的核子成分的增加会导致截面计算值在大角度区域和极小角度区域的增大；小动量核子成分的减小会导致截面计算值在准弹性散射角附近的减小。
  2. All cross sections of neutron induced reaction , elastic scattering angular distribution , neutron energy spectrum and double differential cross sections were calculated by using optical model and the semi - classical model of multi - step nuclear reaction processes based on the hauser - feshbach and exciton model in the energy region up to 20mev
    应用光学模型和以复合核平衡态理论( hauser ? feshbach理论)及激子模型为基础的核反应多步过程的半经典理论，计算了当中子入射能量低于20mev时n + ~ ( 112120 ) sn反应的所有中子入射截面、弹性散射角分布、出射中子能谱以及出射中子双微分截面。
  3. 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。
  4. The calculated double differential cross section of the new model is compared with experimental data and previous scdw calculations with single particle model . the calculated cross sections are larger than those given by previous calculations at backword and forward angles and smaller than those given by previous calculations near the quasi - elastic scattering ( qes ) angle . the agreement with experimental data is much improved
    新模型的双微分截面计算结果与实验值以及以前采用单粒子壳层模型时的计算结果进行了比较，表明cdfm模型的引入对scdw模型的计算结果有较大的改进，使其在大角度和极小角度区域有所增大，在准弹性散射角附近有所减小，从而能更好地与实验值相符合。
