利用差分光学吸收技术结合傅里叶变换，我们在波长207 ~ 217 nm范围内实现了氨和二氧化硫的良好分离。测量表明，路径长度为2分米，测量时间为1分钟，我们可以测量不到1.32 mg/m3 [1.9 ppm（体积）]的氨，标准偏差为0.46 mg/m3 [0.66 ppm（体积）]，干扰为408.73 mg/m3 [156 ppm（体积）]的二氧化硫。
By using the differential optical absorption technique combined with Fourier transformation, we have achieved a good separation of ammonia from sulfur dioxide in the wavelength range 207 to 217 nm. Measurements show that, with a pathlength of two decimeters and a measuring time of one minute, we can measure less than 1.32 mg/m3 [1.9 ppm (volume)] of ammonia with a standard deviation of 0.46 mg/m3 [0.66 ppm (volume)] with interference from 408.73 mg/m3 [156 ppm (volume)] sulfur dioxide.
