| 1. | In this experiment , a neodymium glass laser is used to study the effects of the operating voltage , power density , the height from the observed location of the plasma to the surface of the sample , the location of the sample , the gas composition and the pressure on the intensity and quality of the spectrum
本文采用高能量钕玻璃激光器，研究了激光器工作电压、功率密度、等离子体的观测高度、样品位置、环境气体及气压对等离子体的谱线强度及谱线质量的影响，获得了最佳的实验条件，并测量了金属分析样品中某些元素的含量。 |
