用热表面离子源测定了锂同位素丰度，在样品全耗尽过程中累计离子流强度。
The isotopic ratio of lithium was determined by cumulating intensity of ion current during evaporation of all samples on evaporation filament.
每当测定非常低的浓度和同位素丰度时总是首先使用无机质谱法。
Spectrometry is preferably used each time extremely low concentrations and isotopic abundance are to be determined.

Inorganic Mass Spectrometry is preferably used each time extremely low concentrations and isotopic abundance are to be determined.
结果表明，对不同氘丰度的气体样品，单次测定的相对标准偏差好于0 2 % ，氘丰度测量值在0 2 %的误差范围内是可信的。
The results indicate:relative standard deviations are better than 0.2% for gas samples of different deuterium abundance. Measure value is believable in the error range of 0.2%.
