摘　　要：在空气绝热指数测定仪选型设计中，提出了对其设计应用性能影响较大的诸因素：设定压力值对测定值Ｋ 的影响；毛细现象修正值Δｈ 对测定值偏离理论值Ｋ０ 的影响；推动压差计水柱位移功耗对气筒容积Ｖ２ 的极限容积的要求；乳胶管在气筒内压力作用下对气筒极限容积Ｖ２ 的要求；装置接头泄漏量与气筒容积 Ｖ２ 选型的关系－ 笔者对因素的权重进行了分析。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.
