Beschreibung
Zusammenfassung:	A system and a method for measuring the volume change of rock under the action of microwaves are disclosed. The test cavity is of a sealed cavity structure, and a rock specimen is placed in the test cavity. The microwave control device is arranged inside the test cavity. The strain measuring device includes circumferential strain gauge and axial strain gauge and is attached to the surface of the rock specimen. The measurement circuit is connected with a number of strain measuring devices through lead wires, and the resistance strain gauge is connected with the measurement circuit. After the microwaves emitted by the microwave control device act on the rock specimen, data acquisition is carried out on the rock specimen through the number of circumferential strain gauges and the number of axial strain gauges which are attached to the surface of the rock specimen.
