This document has made the following minimal editorial changes:
---The formulas in 5:7 have corrected formula numbers according to the order of the formulas in the text;
---In 5:3:4, a description is added that my country's sound AM broadcast operates below 29:7MHz;
---The symbols such as eir in Figure 2 and its description have been corrected from lowercase to uppercase, and the international standard is wrong;
---The protection distance stipulated by CISPR is 30m, so the "approximate equivalent interference field strength 20m away from the equipment" in Table 3 is corrected to "distance from the equipment"
Provide an approximate equivalent interference field strength of 30m”;
---"σPV" in C:2:3:3 is corrected to "σCPV":
