介绍了激光诱导击穿光谱(LIBS)技术的原理，重点讨论了该技术在液体样品方面的技术发展和应用，分析并比较了选取不同样品形式(液体内部、液体表面、液体喷流、液滴以及将液体转化为固体等)的优劣，指出提高元素检测限的关键。液体LIBS 技术因其可在线、快速检测等优点，在环境检测、污水处理、生物医药、工业控制等诸多方面具有巨大的应用潜力。

Following a brief introduction of the principle of laser-induced breakdown spectroscopy (LIBS), the recent technical development and its application in liquid samples are reviewed. The merits and drawbacks of different forms of samples, such as liquid bulk, liquid surface, liquid jets, aerosols and solidifying solvent, are compared. Much effort in this technique development is devoted to the improvement of the limit of detection (LOD) of liquid elements. Due to its advantages such as online and rapid detection, the LIBS technique of liquid is supposed to have great potential of applications in many areas, such as environment detection, waste water treatment, biological medicine, industrial control, etc.
