微波烹调的基础是微波介质加热．根据物理原理可知，介质分子可分为有极分子和无极分子两大类．有极分子的正负电荷的中心并不重合而有一段距离，可等效为一个电偶极子．在外电场作用下，使原来杂乱无章的有极分子沿着外电场的方向偏转，产生转向极化（而无极分子在外电场... Microwave cooking is based on microwave heating. According to the physical principle, the media molecules can be divided into two categories: polar molecules and nonpolar molecules. The center of the positive and negative charge of the polar molecule does not overlap and has a distance. It can be equivalent to an electric dipole. Under the action of an external electric field, the original chaotic polar molecules are deflected in the direction of the external electric field, generating a steering polarization (and the non-polar molecules in the external electric field...
