摘　　要：对在用车用液化天然气气瓶的静态蒸发率进行了试验研究,采用两种试验方法(称重法和质量流量计法)和两种试验介质(液氮和液化天然气),进行了静态蒸发率的对比试验。获得了两种试验方法下静态蒸发率测量数值的差异,获得了两种试验介质间静态蒸发率换算系数的试验值,对试验介质(液氮)和实际储存介质(液化天然气)静态蒸发率之间换算关系的理论研究进行了补充。The static evaporation rate of in-service liquefied natural gas cylinders for vehicles was studied experimentally, which was tested by two test methods（weight method and mass flow method） and two test medium（liquid nitrogen and liquefied natural gas）. The difference of static evaporation rate measured by two test methods was obtained, and the experimental value of conversion coefficient of static evaporation rate between two test medium was obtained. Theoretical study of static evaporation rate on the relationship between the test medium（liquid nitrogen） and the actual medium（liquefied natural gas） was added.
