摘要
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 author have quantitatively measured the distribution of temperature and concentration in a spray in an E150 diesel engine by laser double exposure holographic interferometry thchnique. The result have been confirmed by instantaneous sampling technique. A new method have been developed for measuring the process of diesel spray. A useful tool and technique have been provided and developed for the researching and analyzing the distribution of temperature and concentration in the diesel spray.
