摘　　要：微波加热过程主要利用微波的波动性,在加热过程中伴随着趋肤效应.粉碎电磁波加热过程主要利用电磁波的粒子性,在加热过程中的趋肤效应变得很小,同时粒子穿透过程变得很强.在实验过程中还发现有电子浓度起伏的金属表面而会使周围空气温度降低的电子致冷现象.Heating by microwave is mainly based on the wave character of microwave, and the skin effect plays an important role in this kind of heating. While heating by smashed electromagnetic wave is based on the corpuscular property of electromagnetic wave mainly, and in the heating process, skin effect is almost negligible, at the same time, the particle penetration effect is enhanced. In the experiment we discovered that fluctuations of electrons in metal surface can reduce the temperature of the air around the metals.
