neutron moderator 中文意思是什麼
neutron moderator
解釋
中子慢化劑-
The uranium may be put into the reactor in the shape of rods, and the rods surrounded with a neutron-slower, or moderator.
可以把鈾做成棒狀放在原子反應堆內，在鈾棒的四周，圍一層中子減速劑即節速劑。 -
According to the demand of the concept design of china spallation neutron source ( csns ), the target station, i. e. the target, the reflector and the moderator have been simulated and optimized using monte carlo simulation software, nmtc / jam and mcnp4a, firstly. the neutron flux escaping from the target and the moderator and the heat deposition in the target, the reflector and the moderator are calculated. these results provided essential data as a basis of the spallation neutron source design
本論文結合當前中國散裂中子源（ chinaspallationneutronsource ， csns ）工程概念設計的迫切需要，選擇國際上廣泛使用的基於蒙特?卡羅方法，用於模擬粒子輸運過程的程序mcnp4a和nmtc jam作為研究工具，首次對csns靶站進行了全面的模擬與優化，內容包括靶、反射體與慢化器系統的中子通量分佈以及熱量沉積，同時計算了靶的溫度場與應力場分佈。 -
The reflector can increase the neutron flux obviously and the main processes of the neutron yield in reflector are spallation reaction induced by energetic hadrons and ( n, 2n ) reaction. when the moderator height is equal to the distance between the upper part and the lower part of the split target, the total neutron flux of the split target will be higher by 20. 1 % than that of the integral one. secondly, the high - energy neutron escaping from the target will enter into the moderator and be slowed down
得到經水慢化器慢化后，中子通量在慢化器厚度與高度方向上的分佈；比較了水與液態氫的慢化能力以及中子在水、液態氫、液態甲烷這三種慢化器慢化后的能譜；在csns的靶站設計中，引出慢中子的導管不完全位於慢化器中子引出面的法線方向上，因此進一步計算了中子通量角分佈。 -
The neutron flux extracted to different angles has been calculated. finally, the heat depositions in the target, the reflector and the moderator have been calculated. based on these results, the temperature and stress distribution hi tungsten target under different cooling condition have been calculated too
最後計算了靶、反射體以及不同慢化器（水、液態氫、液態甲烷）中的熱量沉積，並以此為依據，利用工程軟體ideas進一步計算了各種冷卻條件下，靶中溫度場與應力場分佈。 -
A low energy neutron resulting from scattering reactions of a fast neutron with the moderator
因中子的動能與其溫度成正比，故而得名。 -
This similarity supports the notion not only that groundwater passing through the oklo deposit was a neutron moderator but also that its boiling away at times accounted for the self - regulation that protected these natural reactors from destruction
這樣的相似性不僅支持流經歐克陸礦床的地下水是中子緩沖劑的理論，也支持地下水沸騰排出是這些天然反應堆自我調控而不致摧毀的機制。
