註釋

The impactions of small particles on cylindrical and spherical collectors was analyzed in terms of the forces which affect the motion of a particle and cause it to move from an aerosol stream onto a collecting surface. Dimensionless parameters which characterize the various mechanisms of collection are defined for inertial separation, interception, electrical attraction, and random molecular motion. Significant values of the parameters were determined. The various theories of impaction of aerosol particles on simple collectors were investigated and extended to a comprehensive statement of the general problem of impaction efficiencies. Practical applications to dust and smoke removal systems are indicated.
