Analysis on the Gas Permeability Measurement of Wood
Zhu Hou · Anhui Nongye Daxue xuebao · 2000
Based on the measurement mechanism and measurement procedure,the accuracy of gas permeability measurement of wood was analysesed in this paper.The results revealed that the approximation of perfect gas and throttling process of gas in practical measuring may cause 0 4 percent of systematic error.The practical measuring errors came mainly from the measuring in flow rate and gas pressure,which accounted 85 percent of the total measuring errors.
