摘要： A thawing method for a heating apparatus, and the heating apparatus. The heating apparatus includes a cavity capacitor used for placement of an object to be treated, and an electromagnetic wave generation module that generates an electromagnetic wave signal used for heating the object to be treated. The thawing method includes: receiving a thawing instruction input by a user, acquiring a feature parameter that reflects the weight of the object to be treated, a power value of the electromagnetic wave signal, and a rate of change in a dielectric coefficient of the object to be treated; and determining the thawing progress of the object to be treated according to the feature parameter, the power value and the rate of change. Compared with determining, according to a sensed temperature of the object to be treated, the thawing progress of the object to be treated, the present invention is less influenced by the precision of a sensing device itself, and achieves relatively accurate determination, thereby facilitating further treatment by the user on the thawed object to be treated.
