摘要：
A process for delivering a predetermined ratio of a compressible fluid and a non-compressible fluid which comprises the measurement of only the flowrate of the compressible fluid, the activation of an air-driven positive displacement pump at appropriate times, the pumping of a non-compressible fluid with the air-driven pump, mixing the supercritical fluid and non-compressible fluid and depositing the mixture onto a substrate.
