用法例句

A detection set-up,composed of a typical grid-ionization chamber and a ΔE-E particle telescope,was constructed to study the charge distributions of fragments in spontaneous fission of 252Cf.

研制了屏栅电离室+ΔE-E望远镜探测器系统,系统的屏栅电离室用来测定252Cf自发裂变碎片的能量和相对于探测器系统轴线的发射角,与屏栅电离室耦合安装的ΔE-E望远镜探测器由一个薄的屏栅电离室(气体ΔE)和一个金硅面垒探测器(E)组成,用来确定互补碎片的电荷。

In order to study charge distributions of fragments in spontaneous fission of 252Cf,a detector system,including a typical grid-ionization chamber and a ΔE-E particle telescope in which a thin grid-ionization chamber is served as the ΔE-section and the E-section is a surface barrier detector,was built up.

为研究252Cf自发裂变碎片电荷分布,建立了由屏栅电离室和ΔE-E粒子望远镜构成的探测器系统。
