摘要
通过在金属样品表面覆盖涂层或改变其表面光洁度的方法， 减少样品表面对激光束的反射， 增大金属样品在激光微光源中的发射强度， 有利于降低光谱分析的检测限。
The reflectance of laser beam on metal surface was considerably decreased by means of daubing a coating or changing the smooth finish.The emission intensity of metal samples was increased in a laser microsource.Therefore,the detection limit of spectrochemical analysis was reduced.
