| 摘 要： | 燃气工程气密性试验的准确鉴定必须采用渗漏率，而不能用压力降。管道和储气罐的气密性主要取决于气用格质表面的渗流速度等，而渗流速度可通过测定压力降来确定。

| Abstract: | The accurate judgement of airtightness test of gas engineering facilities must depend on Leakage rate, but not on pressure drop. The airtightness of materials used on pipelines or gasholders is determined by the leakage rate on the surface of the materials,and the leakage velocity can be calculated with the measured pressure drop. |

| Keywords: | gas pipeline gasholder airtightness leakage rate leakage velocity |
