| 摘 要： | 分析了湿度对容积法检定油封钟罩式气体流量标准装置的影响,建立了湿度对标准体积影响的数学模型。提出了容积法检定方法的改进措施,并评定了改进方法的测量不确定度。验证了水温、环境湿度、大气压力对检定结果的影响,表明容积法检定必须严格控制检定条件和对湿度进行修正。建议采用尺寸法检定油封钟罩。

| Abstract: | The effect of humidity on oil seal of standard bell porvers of gas flow by volumetric method is analysed to establish the mathematical model of the influence of humidity on the standard volume. The measures of improving volumetric method is put forward to assess measurement uncertainty of the new method. The influence of temperature, humidity and atmospheric pressure on the test results is proved. It is showed that test conditions of the verification method must be strictly controlled and corrected on the humidity. The verification seal porvers by size method is recommended. |
