厘清资源环境消耗与经济增长之间的脱钩关系及驱动机制,对福建省发挥国家生态文明建设示范区作用具有重要意义。本研究通过构建"水-能-碳"资源环境投入产出模型,对福建省行业"水-能-碳"资源环境压力进行分析,基于脱钩理论和对数平均迪式指数分解法对福建省各行业"水-能-碳"资源环境消耗与经济增长之间的脱钩状态及其驱动因素进行研究。结果表明:2002—2017年,福建省由虚拟水主导的资源环境压力转变为隐含碳为主导的"水-能-碳"多维资源环境压力,且各行业部门差异较大。从行业部门来看,生产供应业具有较大的直接资源环境压力,制造业部门的间接资源环境压力显著。从脱钩关系来看,福建省的资源环境消耗与经济增长的脱钩状态表现良好,主要表现为弱脱钩和强脱钩。从驱动因素来看,经济效应和人口效应是抑制脱钩的主要因素,而技术效应和结构效应则对脱钩起到促进作用。

＜正＞ Since a novel technique called “high-speed vibration milling”（HSVM） was first applied to the Reformatsky-type reaction of C60 in 1996, this technique has been applied to various kinds of fullerene functionalizations in-cluding the preparation of C120. Most recent reactions of fullerenes under HSVM conditions will be discussed: （1） reaction of C60/C70 with N-alkylglycines and aldehydes （Scheme 1）;（2） reaction of C60 with active methylene com-pounds in the presence of bases （Scheme 2）;（3） reaction of C60 with diazo compounds （Scheme 3）;（4） reaction
