4Fe+302=2Fe2O3, which is the basic reaction equation. At the same time, in order to speed up the reaction, there is also a sodium chloride plasma compound, which makes the whole heating patch form a galvanic cell and speeds up the reaction.

The paper can write the principle of fever, the actual effect of fever, the limit of fever, and also carry out experiments to explain what factors may affect the effect of fever, and if possible, it can be accompanied by some pictures.
