1. A data adjustment method in a radio frequency operation, comprising steps of:
acquiring set power data corresponding to the radio frequency operation, setting an output power of a radio frequency signal according to the set power data, and outputting the radio frequency signal to an object of the radio frequency operation;
detecting physical characteristic data of the object in real time, and determining whether the physical characteristic data exceeds a preset range that is a numerical interval defined by a minimum value and a maximum value by comparing the physical characteristic data with both the minimum value and the maximum value, wherein the physical characteristic data comprises a temperature and/or an impedance of the object;
adjusting a radio frequency output power when the physical characteristic data exceeds the preset range, wherein when the physical characteristic data is greater than the maximum value of the preset range or less than the minimum value of the preset range, it is determined to exceed the preset range; and
selecting target values from various temperature values or impedance values to update the maximum value and minimum value of the preset range according to the physical characteristic data detected in real time in a preset period of time before a present moment and a default selection algorithm when the physical characteristic data does not exceed the preset range.
