s of the external electric field with the high-speed,causing the movement and friction of molecule.so that the microwave field energy can be converted to heat energy in medium to rise the temperature of materials.accomplishing heating ,puffing and a series of physical and chemical processes ,and so ,microwave heating is achieved.
2, The principle of microwave sterilization
The Microwave Sterilization is the result of the role of the microwave thermal effects and biological effects. Affect the
