Comprehensive comparison between nuclear power system and fossil-fired power system by port side an initial inquiry on urgent need and the feasibility of gradually carring out the substitution of nuclear for coal in Fujian Province 核电系统和港口火电系统的综合比较&初探在福建逐步实行以核代煤的迫切性和可能性
Breeding of Elite CMS Lines by Reverse Nuclear Substitution 植物细胞质雄性不育系育种的反向核置换技术分析
METHODS 18F-FDG was synthesized via nuclear reaction 18O ( p, n) 18F on 18O-enriched water and nucleophilic substitution reaction by Tracerlab Mx FDG synthesis system. 方法应用小型回旋加速器,通过18O(p,n)18F核反应生产出18F离子,由亲核取代反应制备18F-FDG,并对所制备的18F-FDG注射液进行质量控制。
Following that, it analyzed the usage of coal, petroleum, the solar energy, the nuclear energy and hydro-energy, based on that, it established substitution analysis table between coal and these resources. 对煤炭、石油、太阳能、核能、水能资源的用途进行了分析,并在此基础上,建立煤炭与其他资源之间的替代分析表。
