Enhancement test equipment, method and device

The invention relates to enhancement test equipment, method and device. The enhancement test equipment comprises a processor, and a first electromagnetic valve, pressure adjusting equipment and a second electromagnetic valve which are connected with the processor. The first electromagnetic valve is used for controlling on/off of a gas path channel between a gas storage tank and an environment box,and is used for applying pressure to a to-be-tested sample stored in the environment box. When the processor detects that the temperature variation of the environment box reaches a preset value, theprocessor indicates the first electromagnetic valve to switch on the gas path channel between the gas storage tank and the environment box, and the gas pressure value of the environment box is adjusted through the pressure adjusting equipment. When it is detected that the gas pressure in the environment box reaches the preset value, the gas pressure in the environment box is reduced. Temperature stress and alternating mech
