柴油机缸内局部燃油蒸气的温度与浓度是影响柴油机着火与燃烧的重要因素，因此研究喷雾油束内燃油温度与浓度分布具有一定的实际意义。作者在Ｅ１５０柴油机上，采用激光双曝光全息干涉技术，假定喷雾油束为轴对称圆锥形，将燃油蒸气作为位相物体处理，测取了喷雾油束的干涉条纹，采用阿贝尔变换对干涉条纹进行反演，导出了油束内轴向与径向位置的折射率，并由此计算出喷雾油束内燃油温度与浓度的分布。讨论了模拟喷雾过程的相似条件，并对大量的试验数据进行回归分析，定量描述了喷雾场燃油温度与浓度的分布及变化历程。
The temperature and concentration of the local fuel vapor in the diesel engine cylinder are important factors that affect the ignition and combustion of the diesel engine. Therefore, it is of practical significance to study the temperature and concentration distribution of the fuel oil in the fuel jet. On the E150 diesel engine, the laser double-exposure holographic interferometry technology is used. Assuming that the spray oil beam is an axisymmetric conical shape, the fuel vapor is treated as a phase object, the interference fringes of the spray oil beam are measured, and the Aberé transform is used to perform the interference fringes Inversion, the refractive index of the axial and radial positions of the oil bundle is derived, and the distribution of the temperature and concentration of the fuel oil in the oil spray bundle is calculated. The similar conditions of the simulated spraying process are discussed. The regression analysis of a large number of test data is carried out to quantitatively describe the distribution and variation of fuel temperature and concentration in the spray field.
