我所有多年研制核子密度含水量测定仪的成功经验。1983年研制成功的ND-A型核子土基密度计曾获得交通部优秀科技成果二等奖和第三届全国发明展览会银牌奖、北京国际发明展览会银牌奖NH-A型中子土基含水量测定仪曾获省科技进步三等奖。结合ND-A和NH-A,我们研制出NDH-A型核子土基密度含水量测定仪,也受到用户的好评。为满足工程上更广泛的实用要求,我们总结了各种核子仪的优点与研制经验,在“七五”国家重
All my years of successful experience in developing nuclear density moisture meters. The ND-A nuclear soil-based density meter successfully developed in 1983 was awarded the second prize for outstanding scientific and technological achievements by the Ministry of Communications, the silver medal for the Third National Invention Exhibition, and the silver medal for the Beijing International Invention Exhibition. Water content measuring instrument won the third prize of provincial science and technology progress. In combination with ND-A and NH-A, we developed the NDH-A nuclear soil-based water content meter, which was also well received by users. In order to meet the more practical practical requirements of the project, we have summarized the advantages and development experiences of various nuclear instruments.
