A review with 37 references is given on the recent progress of selenium species analysis with emphases to the methods of separation and examination technology , e . g , chromatography , the hydride genetic method , inductive coupling plasma mass spectrum , the atomic spectrum
摘要对近年来有关硒的形态分析的发展作了综述，对新的分离方法如色谱法、氢化物发生法、毛细管电泳和新的检测技术如电感藕合等离子体质谱、原子光谱给予较多的关注。
( 5 ) the intensity and s / b of libs are investigated in detail at the different buffer gas , gas pressure , and laser power . the results show that under the 120 mj laser energy , for ar the best s / b is at 200 torr pressure , but for air at 100 torr and he at 300 torr . duration of atomic spectra in ar is longer than that in air
( 5 )实验测定了不同的缓冲气体和气压以及不同的入射激光脉冲能量对原子谱线强度和背景光的影响，结果显示在氩气环境下，当气压约为200torr 、激光的能量约为120mj时， libs的s b最大；在空气和氦气中获得最佳s b时的气压约分别为100torr和300torr ；原子谱线在氮气环境中持续的时间要比在空气中持续的时间长。
