根据中国有色金属工业总公司下达的任务和《新产品开发消化吸收项目合同》的规定,在消化凤凰山引进的库里厄—300型x荧光分析仪技术的基础上,北京矿冶研究总院对七十年代研制的G4—1K型载流x射线荧光分析仪进行改进,研制了尉定的晶体分光组件以代替原有的可调式分光组件;以国际通用的NIM组件构成的记录器代替原有的以分立元件构成的记录仪柜;采用散射法代替原来的反射法进行浓度补偿;研制了以TTL电路构成的程控装置。以上各项重大改进大大提高了该分析仪工作的可靠性与稳定程度,大大缩小了仪器的体积。1985年4月1—2日,中国有色金属工业总公司科技部召集有关部门的领导和专家、研制与使用单位的代表共22人,对该分析仪的性能进行评 According to the mandate issued by China Nonferrous Metals Industry Corporation and the contract of “New Product Development and Consumption Project”, on the basis of digesting the technology of Curie-300 x fluorescence analyzer introduced in Fenghuang Mountain, Beijing Research Institute of Mining and Metallurgy The G4-1K current-carrying x-ray fluorescence analyzer developed in the seventies was improved, and the crystal splitting assembly of Weizeng was developed to replace the original tunable splitting assembly. The recorder, which is composed of internationally common NIM components, was used instead of the original Some of the discrete components of the recorder cabinet; using scattering instead of the original reflection concentration compensation; developed by the TTL circuit programmable device. The above major improvements have greatly improved the reliability and stability of the analyzer work, greatly reducing the size of the instrument. On April 1-2, 1985, the Ministry of Science and Technology of China Nonferrous Metals Industry Corporation convened 22 leaders and experts from relevant departments, a total of 22 representatives from the research and development units, and evaluated the performance of the analyzer
