  二、清华大学王哲团队LIBS相关研究成果及研究最新进展

  

  测量不确定度较高和测量误差大这两大瓶颈严重制约了LIBS技术的精确定量化及大规模商业化。本团队通过研究,提出了等离子体调制、光谱标准化、主导因素偏最小二乘模型等方法,发展了一整套定量化技术,显著的提升了LIBS技术的测量重复性和准确性。各技术成果已经分别通过美国TSI公司、美国B&WTek公司、国电科学技术研究院、国电燃料公司、太原紫晶科技有限公司获得成果转化,总专利转让金额近3000万元,并在本领域首次实现了向发达国家领头企业输出专利技术(美国 TSI 和美国 B&WTek)。

  本团队的技术成果目前已经在煤质分析、手持式 LIBS金属成分分析、水泥生料在线控制方面得到了应用,在节能减排、安全生产、污染控制方面都取得了显著的效益,得到了国际LIBS学术界以及应用单位的认可,推动了LIBS技术以及相关应用领域的进步。
