neutron nuclear reaction
解釋
中子核反應-
The nuclear fissile reaction system, which provides nuclear energy or neutrons, theoretically demands its criticality safety and neutron energy spectrum to be predicated. generally, those are realized by calculating the k - eigenvalue problem
對于提供核能源或中子源的核裂變反應系統，需從理論上給出它的臨界安全性和中子能譜，通常通過k本徵值問題的計算來實現。 -
The target studied in this paper is one of the most important components in the ads. coupling the two innovative fields in the nuclear scientific and technological circles that are accelerator and sub - critical reactor. the physical function of this part is be as the neutron source, accepting the medium or high energy proton, breeding spallation reaction, arising the self - sustaining nuclear fission and generating the power
本文所研究的靶件作為該系統最重要的關鍵部件之一，耦合核科技界的兩大創新領域-高功率質子加速器和次臨界堆，該靶件的物理作用主要是接受中、高能質子，發生散裂反應，產生中子源，引發持續鏈式反應，產生能量。 -
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
應用光學模型和以復合核平衡態理論（ hauser ? feshbach理論）及激子模型為基礎的核反應多步過程的半經典理論，計算了當中子入射能量低於20mev時n + ~ （ 112120 ） sn反應的所有中子入射截面、彈性散射角分佈、出射中子能譜以及出射中子雙微分截面。 -
The evolution of fixed star having something to do with nuclear reaction, the star generally loses partial mass in its final period and finally collapses into compact star ( white dwarf, neutron star or black hole )
恆星的演化與核反應有關，演化到晚期的恆星一般要損失一部分質量，然後坍縮成緻密星（白矮星、中子星或黑洞） 。 -
