1. , for the method for real-time in air fine grained source, it is characterized in that:

  • the method comprises;

    B, by adopting individual particle aerosol mass spectrometer to detect the fine grained in air, thus obtain described fine grain feature spectrogram;

    C, the normalized of proper vector is carried out to the feature spectrogram obtained, thus obtain the normalization characteristic vector corresponding with this feature spectrogram;

    After D, the normalization characteristic vector obtained by step C are multiplied with each proper vector prestored in source characteristics spectrum library, according to the result be multiplied, origin classification are carried out to described fine grained, thus realize the monitoring in air fine grained source.
