双语例句
- When the neutron sensitivity of detectors is calibrated with static accelerator, the intensity of neutron source is measured by BF 3 counting tube+ calibrated counter system and the neutron flux is given by analyzing activated 197 Au.
在用静电加速器中子源标定探测器的中子灵敏度实验中，采用BF3长计数管+定标器系统过渡，用197Au中子活化分析方法达到了对中子注量在线、绝对监测的目的。 - The result shows that use the high density polyethylene as slowing material and create a cylinder round the proportional counting tube that is placed in the focal plane have an ideal detection efficiency for both the fast and slow neutrons.
研究结果表明：用高密度聚乙烯作为慢化材料，做成圆筒形套在正比计数管上，把计数管放置在焦面上，对快慢中子都具有较理想的探测效率。
