摘要: ABSTRACT Formation of nanometer-sized particles in NH3/SO2/H2O/Air mixtures by α-ray irradiation was studied experimentally to evaluate the effect NH3 gas on gas-to-particle conversion process. The total particle number concentration, charged-particle fraction, and electrical mobility distribution generated ionization chamber were measured at various NH3, SO2, H2O vapor concentrations residence times mixture. Particle generation enhanced presence but enhancement depends greatly concentrations; mixing ratios 0.71–3.6 ppm 2–4 higher than those absence constant this range concentration. fraction decreased with addition which indicated that ion-induced nucleation homogeneous enhanced. To gaseous products, kinetic equations...
