| 摘要: |
| 我国自2008年底发布GB/T 22723-2008《天然气能量的测定》以来,开展了大量实验研究与现场测定工作,取得了一系列成果。但由于近年来国际上发布的一系列重要标准在我国尚未转化并贯彻,故在溯源准则建立、分析系统测量误差及其不确定度评估,以及蒙特卡洛模拟及其在能量计量中的应用等方面尚存在缺陷。最后对今后能量计量的技术开发提出了4点建议。 |

| Abstract: |
| Since GB/T 22723-2008 Energy Determination for Natural Gas was issued, a lot of laboratory researches and field tests have been developed as well as many scientific and technological achievements are acquired. Because a series of ISO and foreign advanced standards are not transformed so far, there are some flaws in our technological development of natural gas energy measurement system, such as establishing traceability guideline of natural gas analysis, evaluating measurement error and uncertainty for analysis system, and Monte-Carlo simulation for uncertainty evaluation. Four suggestions about technological development in future are presented. |
