作者描述了根据对连续波氟化氘激光的吸收来测量水中氘浓度的光声方法。这种方法依据这样的事实:氘化水(HDO)吸收某些DF激光辐射,而H_2O实际上什么也不吸收(他们指出,天然水中几乎所有的氘都以HDO形式存在)。他们能得到的探测精度大于10%,但是据说:经适当改进后,达到精
The authors describe photoacoustic methods for measuring the deuterium concentration in water based on the absorption of continuous-wave deuterium fluoride laser light. This approach is based on the fact that deuterated water (HDO) absorbs some of the DF laser radiation and that H 2 O is practically non-absorbing (they indicate that almost all deuterium in natural water is present in HDO). The probing accuracy they can get is greater than 10%, but it is said that after being properly refined, the precision achieved
