The measurement technique of methane emissions from ruminant livestock ushg SF6tracer method was described,which included the basic principle, instrument preparation and the experiment condition.

Laser imaging technology is an important breakthrough for SF6 leakage detection,but feasible verification method was not in hand for this on-line leakage detector in domestic.

The temperature,humidity and the parameter of SF6 gas were overall detected,and the dispersive data were transmitted to the control-center by the wireless module.
