| 摘 要： | 提出了一种新的测试技术－激光干涉层析技术，阐述了这种技术测量任意非轴对称三维瞬变喷雾浓度场与温度场的理论，指出了三维场的测量必须在多个方向上获取全息干涉图这一干涉层析术的特点。提出了一系列独特的全息干涉图的图象处理方法，首次对瞬变喷束两油束交叉区的三维温度与浓度分布进行了实际测量。

| Abstract: | A new measuring technique- laser interfero-holographic and tomographic analysis issuggested.The theory is based on obtaining the concentration and temperature field of anunsymmetrical three-dimensional spray. The paper points out that it is necessary to take differentinterfero-holograms in different directions. A series of methods processing the interfero-holograms are set up.The concentration and temperature distribution of the overlap region oftwo adjacent sprays of a three dimensional transient spray is measured. |
