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。
The paper also has designed investing management system for xi ' an sinco group including three main modules of investment information management , investment monitoring and decision - making according to modularized systematical developing method based on the developing flat of microsoft access2000 database . the investment information management and the investment monitoring modules have been established . and the system realizes the automatic recording , browsing , searching , analyzing , readout , transferring , statistics , analyzing , criticizing etc . and the standardization of work process and the unity of work standardization 按照模块化的系统开发方法，以microsoftaccess2000为数据库开发平台，设计了包括信息管理、投资监控及投资决策三大功能模块的西安新科集团投资管理系统，建立了投资信息管理和投资监控两大功能模块，实现投资信息的自动录入、浏览、查询、分析、输出、传递、统计、分析、评价等功能，规范了工作流程，统一了工作标准。
