The existing methods and devices of degassing fuel liquid, special liquids in weightlessness conditions are expensive and economically not advantageous, since degassing is achieved by a complex, not effective method on the technically bulky devices. The developed methods of degassing fuel liquid and special liquids in the power supply and life-support systems of automatic spacecraft using the controlled vibration or the specially created temperature gradient in the liquid are simple on its construction, economically highly effective and productive. The developed methods permit to produce the unique gasfilled materials with uniform distribution of fine dispersed gas phase using the application of electric field and controlled vibration or electric field and inertial forces in the conditions of space flight. The developed method of processing in weightlessness of antitumorigenic medicines with uniform distribution of spherical drops of cytostatic, which permit during implanting of medicine inside of body parts of patient,which feed by blood tumor, with calculated dose of cytostatic to act directly on tumor cells at the moment of their mitosis.
