    摘要： A process for making particles, the process including generating an aerosol stream which includes droplets of a precursor liquid dispersed in a carrier gas, the precursor liquid including a liquid vehicle and a precursor material, separating the precursor liquid into two portions during the generating step, a first portion exiting the generator in the droplets of the aerosol stream and a second portion exiting as effluent at least a portion of which is recycled to the generator, and also during the generating step adding additional liquid vehicle to at least one of the carrier gas supply, the precursor liquid supply, and the aerosol generator, to at least partially compensate for the tendency of the precursor liquid to become more concentrated in the precursor material over time, and then removing at least a portion of the liquid vehicle from the droplets and forming particles in the aerosol stream.
