    摘要： A method of dissolving a powder material is disclosed in which the material is wholly dissolved and the existence of bubbles in the resultant solution is greatly minimized. An agitating blade stirs a liquid in an air-tight tank while the powder material is inserted into the liquid. The pressure is then reduced in the tank causing large bubbles to swell. The bubbles are destroyed by the agitating blade. The pressure reducing operation is then turned off so that the bubbles do not leave the tank through a pressure reduction port. The pressure reducing operation is then repeated a number of times to dissolve the powder material and to destroy bubbles.
