fission cross section 中文意思是什麼
fission cross section
解釋
對裂截面-
The effect of detector disturb and the shell of the detector and construction material is not distinct. the low absorb cross section material is used to 235u - fission chamber. the low z material is used in experimental bracket and shielding material and the material is used less
獲得了探測器之間擾動、探測器外殼、支架材料對信號中子測量無明顯影響的結果;對~ ( 235 ) u裂變電離室,需採用中子吸收截面低的材料,對實驗裝置的支撐材料和屏蔽材料宜選用低z材料且盡量減少用材。 -
Under the given condition, we have proved the existence and uniqueness of the minimum norm scattering - fission cross section control element, and have given its corresponding optimality conditions
