First, compare whether initial time to the period at current time is less than the first setting time section, for example, first sets
Section of fixing time is 3s, and firing equipment launches radiofrequency signal every 1s, then, it is 12 to carve when initiated:00:When 00,12:00:
When 01, the period of initial time to current time is less than the first setting time section, then by 12:00:00 to 12:00:In 01
The maximum of standing-wave ratio and the difference of minimum value are defined as the fluctuating range of the standing-wave ratio at current time, by 12:00:00 to 12:00:
The maximum of standing-wave ratio and the average value of minimum value are set to the average value of the standing-wave ratio at current time in 01；Carve when initiated and be
12:00:When 00,12:10:When 00, the period of initial time to current time is more than the first setting time section, then, will
12:10:The maximum of the standing-wave ratio in 3s and the difference of minimum value before 00, it is defined as the fluctuation width of the standing-wave ratio at current time

So, can be to determine the fluctuating range of standing-wave ratio and being averaged for the standing-wave ratio at current time at current time
Value.
S202：When the standing-wave ratio at current time fluctuating range and the standing-wave ratio at current time average value ratio meet
When imposing a condition, control and food is stopped heating；
In S202, the fluctuating range of the standing-wave ratio at current time and the average value of the standing-wave ratio at current time are first calculated
Ratio, then judges whether the ratio meets to impose a condition, and in the case of satisfaction, illustrates that food has been heated to target-like
State, control and food is stopped heating.
Wherein, the ratio of the average value of the fluctuating range of the standing-wave ratio at current time and the standing-wave ratio at current time meets to set
Fixed condition can include one or more forms, in a kind of optional embodiment, in S202, and the ripple of the standing-wave ratio at current time
The ratio of the average value of dynamic amplitude and the standing-wave ratio at current time meets to impose a condition, and can include：
The ratio of the average value of the fluctuating range of the standing-wave ratio at current time and the standing-wave ratio at current time is less than setting threshold
Value, and before current time, the variation tendency of the ratio of the fluctuating range of standing-wave ratio and the average value of standing-wave ratio be from less than
Given threshold is to being more than or equal to given threshold.
Wherein, given threshold can determine according to the species of food；In a kind of optional embodiment, given threshold can
With less than 1, for example, given threshold is 0.1.
The ratio of average value of fluctuating range and the standing-wave ratio at current time using the standing-wave ratio at current time can be anti-
The intensity of variation within a period of time of standing-wave ratio is mirrored, because since food just heating, the change of the state generation of food
Change is smaller, and the ratio of the average value of the fluctuating range of the standing-wave ratio at current time and the standing-wave ratio at current time is less than given threshold
When, now the change of standing-wave ratio is smaller, illustrates that food is in stable state within a period of time, is designated as the first stable state；With
Lasting heating, the change that the state of food occurs is increasing, the fluctuating range of the standing-wave ratio at current time with it is current when
When the ratio of the average value of the standing-wave ratio at quarter is more than or equal to given threshold, now standing-wave ratio changes greatly, and illustrates food one
Played pendulum in the section time；Finally, with continuing to heat to food, the change of the state of food is again slack-off, currently
When the ratio of the average value of the fluctuating range of the standing-wave ratio at moment and the standing-wave ratio at current time is less than given threshold, now standing wave
The change of ratio diminishes again, and food is in stable state again within a period of time, is designated as the second stable state；So current time
The fluctuating range of standing-wave ratio and the ratio of average value of the standing-wave ratio at current time be less than given threshold, food is likely to be in
First stable state, it is also possible to which, in the second stable state, when food is in the first stable state, now food is not heated to
Dbjective state, only when food is in the second stable state, i.e., before current time, the fluctuating range and standing wave of standing-wave ratio
The variation tendency of the ratio of the average value of ratio is from less than given threshold, to more than or equal to given threshold, food is by the before explanation
One stable state changes to the second stable state through unstable state, so, just meets to impose a condition.
In an alternative embodiment, in S202, the fluctuating range of the standing-wave ratio at current time and current time
The ratio of the average value of standing-wave ratio meets to impose a condition, and can include：
The ratio of the average value of the fluctuating range of the standing-wave ratio at current time and the standing-wave ratio at current time is less than setting threshold
Value, and before current time, the variation tendency of the ratio of the fluctuating range of standing-wave ratio and the average value of standing-wave ratio be from less than
Given threshold exists to given threshold, and each moment in the second setting time section after current time is more than or equal to
The ratio of the fluctuating range of standing-wave ratio and the average value of standing-wave ratio is respectively less than given threshold.
With it is above-mentioned similarly, the ratio of the average value of the fluctuating range of the standing-wave ratio at current time and the standing-wave ratio at current time
Less than given threshold, food is likely to be in the first stable state, and now food is not heated to dbjective state, only at food
When the second stable state, i.e., before current time, the change of the ratio of the fluctuating range of standing-wave ratio and the average value of standing-wave ratio
Change trend be from less than given threshold to more than or equal to given threshold, before explanation food by the first stable state through unstable shape
State changes to the second stable state, and the second stable state is in, it is necessary to judge working as to more accurately determine food
Each moment in the second setting time section after the preceding moment, if the fluctuating range of standing-wave ratio and being averaged for standing-wave ratio be present
The ratio of value is respectively less than the situation of given threshold, each moment in the second setting time section only after current time,
The ratio that the fluctuating range of standing-wave ratio and the average value of standing-wave ratio be present is respectively less than given threshold, illustrates the standing-wave ratio at current time
Fluctuating range and the standing-wave ratio at current time average value ratio be less than given threshold can last longer, can be true
It is set to the second stable state, i.e. food has reached dbjective state；So, just meet to impose a condition.
S203：When the fluctuating range of the standing-wave ratio at current time and the ratio of average value of the standing-wave ratio at current time are discontented with
When foot imposes a condition, control to food continuous heating.
Specifically, when current time standing-wave ratio fluctuating range and the standing-wave ratio at current time average value ratio
When being unsatisfactory for imposing a condition, illustrate that food is not in the second stable state, it is necessary to be continuously heat foods, until food is in
The dbjective state of second stable state, as food, just stop the heating to food.

State, in the starting stage of heating, the state change very little of food, in varying less for 0-T1 moment standing-wave ratios, illustrate food
Freezing state is also constantly in, is the first stable state, then, between the 0-T1 moment, calculate the standing-wave ratio at current time
The ratio of the average value of fluctuating range and the standing-wave ratio at current time, judges whether ratio is less than given threshold, when judging T1
The variation tendency of the ratio of the average value of the fluctuating range of standing-wave ratio and standing-wave ratio is less than given threshold before quarter, then determines
It is unsatisfactory for imposing a condition, controls to food continuous heating.
With the growth of heat time, since the T1 moment, the change of standing-wave ratio is increasing, until the T2 moment, in T1-
Between the T2 moment, the ratio of the average value of the fluctuating range of the standing-wave ratio at current time and the standing-wave ratio at current time is calculated, is sentenced

Water, food play pendulum, and control to food continuous heating.
When reaching the T2 moment, after the T2 moment change of standing-wave ratio diminish again, after the T2 moment, calculate current time
The ratio of the average value of the fluctuating range of standing-wave ratio and the standing-wave ratio at current time, judge that ratio is less than given threshold, judging
The variation tendency of the ratio of the average value of the fluctuating range of standing-wave ratio and standing-wave ratio is from less than given threshold before going out the T2 moment
To each moment in the second setting time more than or equal to given threshold, and after the T2 moment, the fluctuating range of standing-wave ratio with
The ratio of the average value of standing-wave ratio is respectively less than given threshold, then judges that satisfaction imposes a condition, now illustrate that food has been completed to thaw,
Reach the second stable state, control and food is stopped heating.
