北京先农坛加油站,外表看与其他加油站并无二致,但细心的人还是看出了不同之处。这个加油站距离居民区很近,占地少,而且很少闻到油气味。更为特别的是这个加油站的加油枪上都有一个密封圈,加油时,既不会有油气泄漏出来,更不会泄漏一滴油。 Beijing Xiannongtan Petrol Station is not exactly the same as the other gas stations, but the careful person still sees the difference. The gas station is very close to the residential area and occupies a small area, and it rarely smells of oil. What’s more special is that the refueling gun at this gas station has a sealing ring. When it is refueled, neither oil nor gas will leak out, nor will it leak a drop of oil.
