用激光双曝光全息干涉技术，测取了柴油机喷雾过程中油束内燃油温度与浓度的分布及变化历程，并用缸内瞬时取样技术对全息干涉的测试结果进行了验证。为柴油机喷雾过程中温度与浓度分布的定量测量，为分析柴油机喷雾场的结构提供了一种新的测试手段。
The laser double exposure holographic interference technique was used to measure the distribution and the change course of the temperature and concentration of the fuel oil in the oil spray during the diesel engine spraying. The test results of the holographic interference were verified by the instantaneous sampling in the cylinder. In order to quantitatively measure the distribution of temperature and concentration in the process of diesel engine spraying, a new test method is provided for analyzing the structure of diesel engine spray field.
