On the basis of analyzing a few groups of data,this paper states that our country is getting into the low-level innovation traps.
本文在用多组数据进行分析的基础上,认为我国正在陷入“低水平创新陷阱”。
A method combining solid phase microextraction (SPME) with cryofocus technique was developed for the compound-specific carbon isotope analysis of volatile organic compounds in aqueous phase.
将固相微萃取 (SPME)技术与冷阱富集系统相结合 ,对水体中痕量挥发性有机物进行了单体碳同位素分析 ,方法检测限较常规SPME提高了一个数量级。
In this paper, we developed a method combining SPME with cryofocus technique for the compound-specific carbon isotope analysis of volatile organic compounds in aq.
采用固相微萃取 -冷阱富集GC -IRMS技术对水中痕量挥发性有机物进行了单体碳稳定同位素分析 ,样品经SPME萃取富集后在色谱进样口冷冻成形 ,样品多次进样得以累积从而满足了检测限的要求 。
