【摘要】 采用CPMG自旋回波序列方法研究了柴油-水混合物的核磁共振横向弛豫特性,获得了具有双主峰特征的横向弛豫时间谱,分析了柴油体积分数对双峰位置与强度的影响.结果表明:峰强与柴油体积分数呈现良好的线性相关,利用这种关系可检测柴油-水混合物的成分.更多还原

【Abstract】 The transverse nuclear magnetic resonance（NMR）relaxation of diesel-water mixtures was studied through CPMG spin-echo method.T₂ spectra featured by the obvious main peak of dieselwater were obtained,and the impacts of the volume fraction of diesel on the position and intensity were analyzed.The NMR method for analyzing the components of diesel-water mixtures was proposed based on the linear relationship between the volume fraction of diesel and the peak intensity.更多还原
