核磁共振法测定航空燃油含氢量的研究
Determination of Hydrogen Content of Jet Fuels with NMR Method
【摘要】 采用微型计算机及微处理器控制的核磁共振法,进行测量航空燃油含氢量研究.观测并分析了用射频线圈得到的核磁共振信号的调谐特点,简化了现在类似的测量设备所需的复杂手段.找出了一种能实现快速、方便、精确的测量方法,可作为民航系统普测航空燃油含氢量的有效手段.
【Abstract】 NMR as a method for the determination of hydrogen content of jet fuels controled by PC and microprocessor was described in this paper. The harmonic nature of the NMR signal generated in the radio frequency coil is observed and analyzed. The complicated process of the similar instruments in China was simplified and a fast, simple and exact determination method that can be used for routine to measure the hydrogen content of jet fuels was found.
