摘　　要：介绍了燃烧驱动连续波DF/HF化学激光器的基本结构和工作原理,通过对国内外1973年以来大量文献进行分类和总结,对化学动力学和喷管混合性能研究等关键技术展开了较详细的综述、分析。特别从理论模型、试验研究和数值模拟等3个方面对各国喷管混合性能方面的研究状况进行了较全面的归纳总结;指出了国内研究工作的不足之处以及该激光器相关关键技术的进一步发展方向。认为只要攻克这类关键技术,实现该激光器的高效性、紧凑化进而突破其作为战略武器的局限性,则该激光器仍然具有作为高能武器的优势。The basic configuration and principles of combustion driven continuous - wave DF/HF chemical laser are introduced, and its developments in different countries are summarized. The literature has been surveyed from a lot of published references from 1973 to the present in order to verify the research orientation of the laser and give a reference for investigators. A review of the laser critical technologies on kinetics and nozzle mixing performance are given. The current situation of nozzle mixing performance is analyzed in detail from three aspects of theoretical model, experimental investigation and numerical simulation. The further development orientations of DF/HF laser critical technologies are suggested. It is confirmed that as long as these key technologies are solved, the laser will have high efficiency and compactness, and the limit keeping it from being a strategic weapon will be broken.
