Sulfur dioxide gas, it is the glycerite containing 0.1% bromocresol purple to choose fill second；Under conditions of 70 DEG C, the step
3~57% injection fill first of internal layer containment vessel volume in two, remaining is the air of 1.8~2.0 atmospheric pressure；At 70 DEG C
Under conditions of, 10% injection fill second of outer layer containment vessel volume in the step 3, remaining is 1.6~2.0 air
The air of pressure；The volume of internal layer closed container is a quarter of outer layer containment vessel volume；Internal layer closed container is in interior outer gas
Pressure difference ruptures when being 1 atmospheric pressure；
Detection temperature is reaches 60 DEG C from 150 DEG C in the step one, choose fill first be 70.0% calcium chloride water and
0.05 gram of copper powder, it is nitrogen dioxide and dinitrogen tetroxide mixed gas to choose fill second；Under conditions of 150 DEG C, the step
60% injection fill first of the volume of internal layer closed container in rapid two, remaining is the air of 2.0 atmospheric pressure；At 150 DEG C
Under the conditions of, the step 3 kind outer layer closed container injects the fill second of 1.6~2.2 atmospheric pressure；Internal layer closed container
Volume is a quarter of outer layer containment vessel volume；Occur when outer draught head is 0.5 atmospheric pressure including internal layer closed container
Rupture.
2. one kind according to claim 1 is disposable to cross temperature detection method, it is characterized in that：The material of the internal layer closed container
Matter selection is firmly, not with fill first and fill second to react and when external and internal pressure difference exceedes certain atmospheric pressure
The material ruptured；The material selection of the outer layer closed container is firmly, not to occur with fill first and fill second
Hair should and will not rupture under the air pressure of 3 atmospheric pressure, transparent material.
