  1. 0.77 or (0.74 ~ 0.88) in the table were aerodynamic diameter of FPSL as statement and ATD particle as measured by laser diffraction method. Mean ± SD was used to indicate the range of sampling efficiency. Welch Two Sample t-test was used to assess the difference between evaluation results of monodisperse and polydisperse aerosol, and p < 0.05 was considered statistically significant.
