我国液化天然气加气机量传体系的建设

摘要

随着我国液化天然气（LNG）加气站和LNG汽车的不断增加，LNG加气机日益得到广泛的应用。为此，以LNG加气机的原理为切入点，介绍LNG加气机国家检定规程及型评大纲的制定工作，分析LNG加气机的量值溯源和传递，展望我国LNG加气机产业的发展趋势，这对促进我国LNG加气机产业的健康有序发展、加快LNG加气机量传体系的建设和研究工作具有重要的指导意义。%With the rapid increase of the LNG gas stations and the LNG vehicles ,the LNG dispensers are increasingly available .The working principle of LNG dispensers as the starting point ,the national verification regulation and the program for pattern evaluation of LNG dispens-ers are introduced .The traceability and transfer of quantity of LNG are analyzed .The developing tendency of LNG dispensers in China is prospected .The research results of the paper will pro-mote the development and study of LNG dispensers industry .
