中文摘要：

为了了解四川省液化石油气产品质量安全现状和加强液化石油气产品质量安全监管提供依据，国家石油天然气产品质量监督检验中心在全省范围内共采集了100个批次的液化石油气样品进行检测。检测结果显示，液化石油气的合格率仅为62％，造成液化石油气不舍格的主要原因是大多数液化石油气中掺杂了二甲醚。可以看出，四川省的液化石油气产品质量现状并不乐观。

英文摘要：

To find out the current liquefied petroleum gas quality safety in Sichuan province and provide foundation for strengthening quality safety supervision and administration, 100 liquefied petroleum gas samples were selected and tested by China National Quality Supervision ＆ Inspection Center For Petroleum and Natural Gas. Testing result showed that the pass rate of liquefied petroleum gas was only 68~. The main reason for the failure is that most of the liquefied petroleum gas is adulterate with dimethyl ether. It can be concluded that the liquefied petroleum gas product quality is not optimistic in Sichuan province.
