threshold neutron 中文意思是什麼
threshold neutron
解釋
閾能中子-
When the energy distribution of secondary neutron are represented by evaporation spectrum ( lf = 9 ), care must be taken in describing the nuclear temperature near the threshold
通過分析發現，評價次級中子能譜數據所採用的蒸發譜模型大都忽略了能級密度參數與激發能之間的關聯。 -
We take 3. 5 solar masses as the benchmark for judging whether something is a black hole because we know we know that theoretically the mass of other compact objects like neutron star cannot exceed that maximum threshold. otherwise those bodies will collapse under their own gravitational force into black holes
我們以質量大於太陽的3 . 5倍作為判別黑洞的標準，是因為從理論上得知，其他緻密天體如中子星的質量都不可能超越這個上限，否則它們便會因為本身的重力而塌縮成黑洞。 -
Calculation of absorbed dose from neutron irradiation by application of threshold - foil measurement data
用分界箔測量數據計算來自中子輻射的吸收劑量 -
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。
