nuclear fragmentationとは 意味・読み方・使い方

This structure is constituted by combining integrally a first layer shielding material 11 formed of a light material of low density which generates hardly nuclear fragmentation by action of the charged particle of high energy incident from an outside to decelerate the charged particle of high energy with a second layer shielding material 13 formed of a heavy material of high density to decelerate the incident charged particle effectively.例文帳に追加

外から入射してくる高エネルギー荷電粒子の作用で核破砕を起こし難い密度が小さい軽材料で形成して前記高エネルギー荷電粒子を減速する１層目の遮蔽材１１と、密度が大きい重材料で形成して入射した荷電粒子を効果的に減速する２層目の遮蔽材１３とを一体的に組み合わせて構成した。 - 特許庁
