符合计数 meaning in English
coincidence counting
Examples
- The simulation can be divided into three processes sequentially : calculating the induced fission neutron rate of uranium and space distribution by mam - li neutron source , computing the total uranium fission neutron count rate and time distributions of 42 3he tubes , and calculating the neutron coincidence counting rate
第一步，以ain ? li源为中子源，计算铀的诱发裂变中子产生二率及空间分布；第二步，以铀的诱发裂变中子为中子源，计算化根’ ne管的总中子计数率及时间分布；第三步，计算中子符合计数率。 - In order to meet the requirements of nda measurement , the laboratory of technical research for nuclear safeguards of china institute of atomic energy ( ciae ) , is being in charge of developing four sets of nda standards : one set of segmented gamma - ray scanner ( sgs ) uranium standard , one set of sgs plutonhim standard , one set of plutonium isotopic standard , and one set of active well coincidence counter ( awcc ) standard . in this dissertation some pivotal techniques on quality control in developing of nda nuclear standards above were emphatically studied
中国原子能科学研究院核保障技术重点实验室研制分段y扫描装置( sgs ： segmentedgamma - rayscanner )铀工作标准样品、 sgs钚工作标准样品、钚同位素标准样品和有源中子井型符合计数装置( awcc ： activewellcoincidencecounter )铀工作标准样品来满足核材料nda测量的要求。本论文重点对上述nda核标准样品研制过程中质量控制的一些关键技术进行了研究。
