摘      要：The earth is an enormous open system and the gas-releasing phenomenon of the crust is the major means of exchange of matters and energy at different crustal ***,a powerful gas-releasing channel is actually a window to understand the subterranean physical and chemical variations as well as stress-strain *** releasing places,quantities and ways obtained by systematically observing and recording can reveal the pressure variation and opening state of channels in the crust,and furthermore provide important information for earthquake prediction,tectonic activity and monitoring of volcanic *** fracture-gas measurement has been applied widely to earthquake sciences and has played an important *** authors introduced systematically the application situation and preliminary achievements in China,and pointed out that though this technique is at the beginning stage and not very sophisticated but its capacities for being easy-carrying,fast-operating and inexpensive,makes for a
