| 摘 要： | 利用核磁共振成像分析仪测量了不同汽油体积含量的乙醇汽油溶液的核磁共振信号,分析了横向弛豫时间、信号强度与汽油浓度的关系.结果表明乙醇汽油溶液中汽油的体积含量与信号强度呈线性关系,因此利用低磁场核磁共振可以测量乙醇汽油浓度.

| Abstract: | Relaxation signal of different gas volume content of ethanol-gasoline were measured by nuclear magnetic resonance imaging method.The relationship between transverse relaxation NMR signal intensity and the gas concentration was analyzed.The result showed that the gas volume content in the ethanol-gasoline solution and the intensity of the signal had good linear relation.Eventually a new method using low field nuclear magnetic resonance to measure the concentration of ethanol gasoline was given. |

| Keywords: | nuclear magnetic resonance ethanol-gasoline transverse relaxation time signal strength |
