　　一、清华大学王哲团队风采

　　清华大学能源与动力工程系激光诱导击穿光谱研究团队，由倪维斗院士、李政长江学者、王哲教授、候宗余助理研究员为核心成员，目前有在读博士生4名，在读硕士生1名，在读本科生2名，及4名工程师。团队为电力系统及大型发电设备安全控制和仿真国家重点实验室组成部分。

　　本团队自2008年至今，一直致力于LIBS机理和定量化技术的研究，本团队研制的“激光诱导击穿光谱(LIBS)定量化技术”项目，被仪器仪表学会鉴定为“整体处于国际领先水平”，并荣获了2017年度中国仪器仪表学会科学技术奖一等奖。

　　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。

　　LIBS煤质离线/在线分析仪。快速对煤炭进行元素分析和工业分析，便于实现在线测量。用于煤炭定价和燃烧优化。可重复性和准确性接近传统方法国标。性能获得第三方鉴定。已获得国电集团、美国TSI 支持，正在推进在线检测示范项目。

　　手持式金属分析仪，可重复性接近XRF，准确性优于XRF，可以测量轻元素(如碳、硅);无辐射风险;获中国光学工程学会第三方鉴定。

　　水泥生料品质在线检测系统，在线测量三率值并指导原料配比。水泥生料合格率由~50%提高至88%.显著提高水泥成品率及企业效益 (和山西大学合作)
