aerosol mass density的用法和样例：
- The influence of the temperature and relative humidity upon aerosol mass concentrations distributions has been discussed.
- The result indicates that the model reflects the influence of the temperature and relative humidity to aerosol mass concentrations distributions.
- It is indicated that the aerosol mass concentration vertical distributions retrieved by both the models are consistent with each other, and consistent with facticity.
