摘要在信息化社会，科学技术总是日星月异。尤其是在激光领域，不断有突破性的研究进展。从二十世纪以来，发展过来的激光诱导等离子体光谱分析技术LIBS（Laser Induced Breakdown Spectroscopy）在物质元素研究和分析领域取得一大成果。LIBS已经在工业领域的各个发光面起着相当重要的作用。回顾一下激光诱导等离子体光谱分析技术的发展历程，我们从时间上，整个过程可分成三阶段：从六十年代到七十年代之间，实验室中普遍采用光电火花源来诱导等粒子，虽然和之前的实验方法相比，得到的光谱品质有所改善但是还是没有达到我们要求的高度，它主要表现在较差的检测能力，在分析光谱精度过程中尤为体现出来；到了七十年代和八十年代之间，计算机技术的发展不断的向前推进，时空分辨技术得到了更加广泛的应用，我们可以改变材料周围的环境参量，再使用激光去冲击材料诱导等离子体；从九十年代至今，科技跨越式的发展导致一轮又一轮的科技产品不断地更新，最终产生了LIBS技术。这个突破对于瞬态光谱的研究有了本质上的推动和促进，与此同时，也为经后在激光光谱研究领域开辟了一番新的天地。
我们需要指出的是作为多学科交叉结合的分析测试技术——激光诱导等离子体光谱LIBS，是光和物质相互作用尤其是光和金属物质相互作用领域的重要研究课题。长期以来，LIBS一直都被广泛的应用到矿业采集，环境分析，激光加工，激光冲击等等多个领域。LIBS可以做到对微观物质的物理结构，宏观物质的化学成分组成进行检测和分析，并且是不限于所要检测样品的尺寸。当前，研究者们不断探索激光诱导过程中，各种参数如气体环境，靶材的周围环境，靶材自身的化学特性物理特性对实验的影响。
本文我们首先介绍了我们这次试验所需要的主要器材以及器材的详细信息，这是重要的，因为器材的选择对于采集到的光谱以及最终光谱分析的精度有着很大的作用。然后我们需要掌握本实验的原理方法，列出我们这次试验需要解决的问题，指出我们这次试验所需要采用的检测手段。然后我们进行实验，采集数据，分析光谱。我们通过控制变量法，控制激光光能始终保持不变，改变延迟类型，获得不同的光谱。对这些光谱进行比较、分析，最终得到具有可行性的规律。为以后LIBS应用到工业领域飞跃作出努力。

Abstract with the development of the technology of laser,Laser Induced Breakdown Spectroscopy named shortly LIBS leads to a new time when we start to analyze the element substance ,which emerged in 2000s. This technology has been applied in various industry fields.for LIBS ,it went through about three period: we often use optic-electric fire to induce plasma in the labor.though the optic spectrum we get in that way has been improved ,it still can not meet our command.it is weak in detecting ,especially when it is applied in analysis of spectrum accuracy.when it comes to the 1960s ,in the following 10 years ,the PC technology is developing fast as it was .temporal special resolution has been applied in the broaden field. maybe we can change the environment parameters surrounding the target material or something dealing about material itself.and then we can use LASER to lash the material for the plasma .from the 1990s to this day,technology has stepped stride.it goes on from that time to next time and never delays,which leads to the technology LIBS.the breakthrough can motivate the research of the instantaneous spectrum in the potential.and also due to it,a new research area has been exploited about the spectrum studied by laser.
