　　The national standard material resource sharing platform mainly provides reference material information inquiry, physical sharing and promotion, R & D and application technology exchange, resource planning and development research and other information. The standard material resources sold involve 13 application fields such as environment, chemical industry, steel, geology, physicochemical, non-ferrous metals, nuclear materials, food, clinical, coal, engineering technology, building materials and polymer materials. Its website has passed one of the 23 national science and technology platforms identified by the Ministry of Science and Technology and the 2011 performance appraisal. While ensuring operation, through continuous improvement of capabilities, it continues to move forward in the direction of the National Standard Material Development Strategy Center, Standard Material Knowledge Dissemination, Achievement Transformation and Sharing Center, Standard Material Common Technology Reserve Center, and Standard Material International Technical Cooperation Center!
