Abstract：An experimental system for testing small-scale gas explosions was designed and con-structed. The concept of an induction period associated with the gas explosion was discussed. The induction period is broken into two parts: the combustion and the explosion inductions pe-riods. When the visible light front increases to e~m times the original rate it is said that combus-tion has transformed to explosion. This is based on the induction period in thermal explosion and chain reaction theory and on the nature of the light emitted by the reacting gas. A way to determine the induction period was given. The induction periods of the combustion and the ex-plosion are almost linear with gas concentration. The effect of gas concentration on the induc-tion period is small when the ignition energy is large.
