This article summarizes the research trends of injection and pneumatic technology. Emphasis is given to the research progress of injectors, jet cutting, spraying, jet combustion and pneumatic technology and their application in national economy. The history of jet and pneumatic technology has a long history and is a practical technology that is widely popularized at present. It also includes modern high and new technology. The content is very rich and extensive, forming a huge family. According to its use can be divided into the following twelve categories: (1) injector; (2) jet cutting; (3) spray; (4) jet combustion; (5) pneumatic detection; Spray irrigation, spraying and jet cleaning and fire; (8) spraying, spray welding and shotcrete; (9) jet spinning; (10) jet drilling; (11) jet engine; (12) modeling and control. This technology has been widely used in many sectors of the national economy and has produced very significant economic benefits. This article focuses on the research trends of the previous types and their applications.
