The invention discloses a method for drying articles by using an ultrasonic in combination with a supercritical fluid. The method comprises the following steps of: placing and sealing articles to be dried and an ultrasonic transmitting device into a supercritical fluid dry jar, firstly introducing dry media into the supercritical fluid dry jar, simultaneously opening the ultrasonic transmitting device and a supercritical fluid circulation valve when the pressure and the temperature in the supercritical fluid dry jar reaches 7.5-100MPa and 35-95 DEG C respectively, wherein the ultrasonic frequency, the ultrasonic power, the ultrasonic intensity, and the ultrasonic irradiation time are controlled to 16-500kHz, 50-5,000W, 0.2-5,000W/cm<2>, and 10min-10h respectively, and an ultrasonic irradiation manner is intermittent or continuous; controlling the flow speed of the supercritical fluid circulation valve to 0.5-100L/h; and after ultrasonic irradiation is finished, opening the dry jar and taking ...
