[0016] The gas or gas-liquid mixed substance in the reaction tube 10 is heated and reacted, when the gas or gas-liquid mixed substance in the reaction tube 10 needs to be heated and reacted, first, start heating tile 5 and the heating wire 6 in it, the uniform distribution and effective transmission of the heat of heating wire 6.
[0017] The heat generated by the heating wire 6 is first transferred to the inner heating tile 5. Since the inner heating tile 5 has a constant temperature heat conduction zone 7 in its interior, the constant temperature heat conduction zone 7 is made of heat conductive material, the heat is quickly and evenly distributed in the entire constant temperature heat conduction zone 7. At the same time, the outer heating tile 5 and the bottom plate 4 also transfer heat through the heating tile 5. However, since the outer heating tile 5 and the inner wall of the furnace body 1 are separated by the heat preservation zone 2 filled with heat preservation material, the rate of heat loss to the outside is greatly reduced.
[0018] The reaction tube 10 is inserted into the socket 8 at the top of the constant temperature heat conduction zone 7. The end of the reaction tube 10 closer to the inner heating tile 5 receives more heat than the end farther away from the inner heating tile 5, resulting in a temperature difference.

Therefore, grooves one 13, grooves two 15, grooves three 16 and grooves four 17 are provided. The grooves one 13, grooves two 15, grooves three 16 and grooves four 17 are hollow gaps, so the heat conductivity is poor. Grooves five 12, grooves six 18 and grooves seven 19 do not fit the outer wall of the reaction tube 10, so the heat conduction is also reduced. In this way, the problem of large temperature difference in the reaction tube 10 can be solved. The temperature difference in the reaction tube 10 can be controlled within a small range, and the temperature difference in the reaction tube 10 can be controlled within a small range.
[0019] Under the action of heating, the substances in the reaction tube 10 begin to react chemically. Since each reaction tube 10 is in the same heating environment, their reaction conditions are consistent, which helps to shorten the test time and improve the stability of the data.
