For example, the angle range during the rotation of the waveguide converter is 0-360 °, and the movement process of the waveguide converter is divided into 18 movement states by presetting a step size of 20 °.
It should be noted that the implementation manner of obtaining the N corresponding motion states of the waveguide converter is only an example, and is not limited herein.

In this embodiment, M motion states with better microwave absorption conditions may be determined as effective motion states from the N motion states according to the energy absorption parameter corresponding to each motion state, where M is a positive integer.
As an example, a preset threshold may be obtained, the energy absorption parameter corresponding to each motion state is compared with the preset threshold, M target motion states corresponding to the energy absorption parameter being greater than or equal to the preset threshold are determined, and the M target motion states are taken as M effective motion states.

ΔT(t)＝x1·ΔT1+…+xm·ΔTm
Wherein x is1+…+xm1, the total heating time is known as t, where x1…xmFor the unknowns to be solved, the uniformity of the overall heating is represented by the coefficient of variation (COV), and the smaller the value of the coefficient of variation COV, the more uniform the overall heating. Wherein the COV value is in the form of a mean square error/mean, i.e., the mean square error of the temperature rise values of each region in Δ T (t) is divided by the mean temperature rise value. Furthermore, each time distribution coefficient when the coefficient of variation COV is the minimum value is determined by a conditional extremum solving method of the relevant M-ary function, so that the M heating times of the waveguide converter in the M effective motion states are further determined according to the time distribution coefficients and the heating times t corresponding to the M effective motion states.
