设计产品时应优先选择能耗较高的材料（）In material selection of an eco-design, priority should be given to materials with high energy consumption in its production（）

A、STAF关注特定区域,而动力学方法关注物质质点 Specific regions are concerned in the STAF framework, while matter particles are concerned in the dynamic framework

B、STAF考虑了贸易,而动力学方法不需要考虑贸易 The trade between regions needs to be considered only in the STAF framework rather than in the dynamic framework

C、STAF考虑了物质使用存量(In-use Stock), 而动力学框架未考虑 The material in-use stock is considered in the STAF framework but in the dynamic framework

D、STAF框架显化了废物回收与处置,而动力学框架隐含了该阶段 The waste management and recovery is structured in the STAF framework while it is hidden in the dynamic framework
