液態靶 的英文怎麼說
中文拼音 [yètàibǎ]
液態靶
英文
liquid target-
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。In the way based the scientific and tecdrical talks on i presided at and panicipated in, the graduation theis included a p1entful thets in recent years wtll be divided into three parts for depiction conxteniently and clearly, according to the content as fo1lowsf ( l ) the study of shock compression properties with the drixtiir - liquid co and n, experimentally ( 2 ) the study of the phenomenon of excess heat produced by deuteriurn atoms entering into the lattice of titaluxn experimentally ( 3 ) the calcujation for the electronic structure and energy of hydrogen atoms cluster ffi. the mainstream in the first part of the paper is to exposure some experimental tecndques in high pressure and high temperatur shock compression physics, including by using a cryo - target cooled down circulating steaxned n, to condense the well - proportioned mixed liquid sample from pure gas co and n = with equal molar voiurne
根據近幾年所承擔和參加的科研任務，將研究成果總結寫成的論文按以下三個部分敘述： （ 1 ）液體co和n _ 2混合物沖擊壓縮特性的實驗研究（由國防科技重點實驗室基金項目96js75 . 2 . 1 . jw1902資助） （ 2 ）重氫原子進入鈦晶格中引起過熱現象的實驗研究（由國家自然科學基金10145002資助） （ 3 ）氫原子團簇h _ 9的電子結構與能量計算第一部分以高溫高壓沖擊波物理實驗為主，採用自行研製的低溫循環汽冷靶冷凝制樣技術由高純co和n _ 2氣體獲取等摩爾體積均勻混合的液體沖擊初態樣品。A series of results are achieved such as fluid field thermal field pressure field and stress field. those results show that sphere target has better heat exchange and convenient fluid structure and that cone target is easy to accepting neutron and has the convergent stress. taking into account the thermal - hydraulic and physics discipline, solid target choose sphere structure but liquid target still should further consider of material study
計算結果表明：圓球靶型散熱快，流道設計方便;錐形靶易於接收中子，但結構易引起應力集中，在綜合熱工、物理兩個角度，固態靶選取圓球型鎢靶比較滿意，液態靶區的計算需要在材料研究的基礎上進行。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。分享友人
