目前,在天然气计量标准中有如下问题: 1.原规定(SYL40-83及GB1314-77)标准状态下,计量所得的体积并不是视理想气体的体积(即所计量的22.4×10~(-3)m~3气体不为 1 mol该气体),这就给质量计量带来不便。 2.在我国一些要进行质量计量的用气单位,常采用物理标准状态(即1物理大气压——1.0133×10~5Pa,0 摄氏度——275.15K)作为体积流量的标准状态。我们与其标准状态不统一,这就给供、

At present, the following problems are found in the measurement standards of natural gas: 1. The original regulation (SYL40-83 and GB1314-77) In the standard state, the volume measured is not the volume of the ideal gas (that is, the measured volume of 22.4 × 10 ~ 3) m ~ 3 gas is not 1 mol of the gas), which brings inconvenience to the quality measurement. 2. Some units of gas to be used for mass measurement in our country often use physical standard state (ie 1 physical atmospheric pressure - 1.0133 × 10 ~ 5Pa, 0 ° C - 275.15K) as the standard state of volume flow. We and its standard state is not uniform, which gives,
