neutron-proton ratio 中文意思是什麼

neutron-proton ratio 解釋
中子質子比
  • neutron : n. 【物理學】中子。n. -ics 中子(物理)學。
  • proton : n. 【物理學】(正)質子;氕核,氫核始基;精朊腖。 proton decay 質子衰變。 proton-force 質子間力。 proton-scattering 質子互致散射。
  • ratio : n. (pl. ratios)1. 比,比率,比值;比例;系數。2. 【經濟學】復本位制中金銀的法定比價。vt. 1. 用比例方式表達;求出…的比值;使…成比例。2. 將(相片)按比例放大或縮小。
  1. The effect of the autogeny target neutron relates to the target time being used. when the ratio of the proton ( d - d ) counter and a particle counter exceed the experimental need, the target must be changed in time

    自生靶中子的影響跟靶使用的時間有關,當質子( d + d反應)計數粒子計數比值超過實驗規定要求時,應及時改用新靶。
  2. We have further studied equilibration with respect to isospin degree of freedom and proposed that the neutron - proton differential rapidity distribution is a sensitive probe to the energy dependence of the degree of equilibration : there exists memory effect in multifragmentation process ; the degree of equilibration at e = 400a mev qingfeng li, isospin in hics and k production at near threshold is higher than that at eiooa mev ; the average n / z ratio of imf reduces largely as beam energy increases from 100a mev to 400a mev

    進一步地,利用不同的同位旋相關觀測量我們還研究了系統平衡程度問題,發現中子-質子差的快度分佈可以探測到入射能量達到400amev時反應系統的平衡程度比100amev入射能量時要高,中心快度區的系統基本達到平衡,而彈、靶快度區則存在明顯的入射道效應。
