The chromogenic reaction of gold with malachite green in the presence of span 20 在span20存在下孔雀石绿与金的显色反应研究
Research on the Principle of Green Product Long Life Span Design 绿色产品长寿命设计原则初探
Furthermore, applying the activity-based costing method, the cost analysis functions of green product design on every stage are discussed synthetically, and the cost analysis model involving the whole span of products 'life cycle is set up. 在此基础上,运用基于作业的成本分析(ABC)法,全面论述了绿色产品设计各个阶段的成本分析函数,建立产品全生命周期的成本分析模型。
