Method for determining the characteristics of crude oils and mixtures of chain molecules by diffusion, relaxation and density measurements
Abstract:
The diffusion coefficients and relaxation times of mixtures of alkanes follow simple scaling laws based on the chain length of the constituents and the mean chain length of the mixture. These scaling laws are used to determine chain sizes in a mixture from the distribution of the diffusion coefficients. These scaling laws can be used to determine the mean chain lengths (or chain lengths) of a sample (alkanes or mixtures of alkanes) and therefore the constituents of the sample.
Abstract(Chinese):

基于成分的链长和混合物的平均链长度，烷烃混合物的扩散系数和弛豫时间遵循简单的比例定律。 这些缩放规律用于根据扩散系数的分布来确定混合物中的链尺寸。 这些缩放规律可用于确定样品（烷烃或烷烃混合物）的平均链长度（或链长度），因此确定样品的成分。
