缓冲气体 meaning in English
buffer gas
cushion gas
Examples
- ( 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。 - The main contents are as followings : ( 1 ) the rules of choosing characteristic lines of fe and ni elements in the cu - pb alloy are investigated ; ( 2 ) the characteristic line of the impurity element and that of the reference element makes up a line pair . the intensity ratio of the line pair measured as an y - axis and the corresponding concentration ratio as x - axis , calibration curves for composition analysis is fitted at the 4 kinds of buffer gases
Q ）采用内标法，由样品中杂质元素的分析线和内标元素参考线组成分析线对，对五种不同的铅黄铜样品，实验通过测定了杂质元素分析线队的强度比，以分析线对的强度比为纵坐标、分析线对所对应元素的含量比为横坐标，拟合出了一系列在四种缓冲气体中的定标曲线。
