摘要：In this study, we analyze and describe the carbon distribution of n-paraffin in five kinds of diesel fuel, particularly using mathematical statistics. At the significance level alpha = 0.10, the distributions of all these diesel fuels submit to the normal distribution. The n-paraffin, with a lesser variance of sigma(2), shows a weak sensitivity of flow improver. Statistic test quantity chi(2) reflects whether carbon distribution of n-paraffin fits the normal distribution. While the carbon distribution does not fit the normal law well, it will be difficult for this diesel to decrease the Cold Filter Plugging Point (CFPP).
