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，从而进一步提出了符合课堂教学演示和实验教学应用要求的选型设计方法
In the selection design of air-heat-insulation indexer, the factors influencing the design and application performance are put forward: the influence of setting pressure on the measured value K; the effect of the capillary value correction Δh on the deviation of the measured value from the theoretical value K0 ; Pressure differential meter water column displacement power consumption of the cylinder volume V2 limit volume requirements; Latex tube in the cylinder pressure under the pressure of the cylinder limit volume V2 requirements; Device connector leakage and cylinder volume V2 selection of the relationship - the author of The weight of the factors were analyzed, thus further proposed in line with the classroom teaching demonstration and experimental teaching application selection design method
