目前，我国大规模交接计量基本上都使用体积计量，为使我国商品天然气的交接计量与国际接轨，正准备由体积计量向能量计量过渡。章主要阐明了有关过渡方面的5个问题：（1）实施天然气能量计量并非单纯计量技术的进步；（2）发热量准则是体现能量计量科学上准确性的基础；（3）目前国内外普遍采用计算法确定发热量，我国今后在能量计量中也将采用此法，但必须以直接法为基准进行校核后才能制定相应标准；（4）实施天然气能量计量涉及多种在线测定仪器，目前我国基本上依靠进口，也缺乏现场使用经验，对此应及时做好准备工作；（5）应根据我国的法令，法规及时完善有关能量计量的标准体系。

Some Legal Problems Related to Gaging Natural Gas Energy

??At present,the volumetric measurement is basically used for the large-scale metering in China.In order to coordinate the metering of marketable natural gas in China with that in the world,it is preparing to transform the metering from volumetric measurement into energy gaging,about which there are five problems:??the implementation of gas energy gaging isn't the progress in metering techniques;?? calorific value criterion is the basis of embodying scientifically the accuracy of the energy gaging;?? the calculating method is commonly adopted for determining the calorific values at home and abroad at present and it will be applied to the energy gaging in China in the future,however,only after having been checked up on the basis of direct method,can relevant standard be drawn up;?? some preparing works should be made up in time,because many kinds of on-line measuring devices,of which most are imported from foreign countries and less used on-side in China,are involved with in implementing natural gas energy gaging;and ?? the standard systems related to energy gaging should be perfected in time according to our country's decrees and statutes.
