A Study on Model Selection of Air Adiabatic Index Instrument

In the design and application of air adiabatic index instrument,The performance of the instrument is directly or indirectly impacted by the follewing factors,the capillary phenomenon correction Δ h and the set pressure′s effects on the measurement value K ,and the power loss of displacing pressure gauge water and the emulsion tube pressed by internal pressure and the equipment connection seepage′s effects on the limit volume V 2 of the gas tube,and so on.After weighing all these affections,this paper further produces a model selection method,applicable to classroom and laboratory demonstrations.
