利用（289，313；277.1，299.1nm）或（268.4，289；277.1，299.1nm）4波长进行双差分吸收可以用于对流层大气气溶胶含量丰富或分布不均匀地区臭氧的测量。

• The dualDIAL with (289, 313: 277. 1. 299. 1nm) wavelengths or (268. 4, 289: 277. 1, 299. 1nm) wavelengths can be used for ozone measurement in the region, where aerosol loading is high or distribution inhomogeneous in the troposphere.
