Problems solved by technology

However, at present, there is a lot of research and practice on the design of explosive devices at home and abroad. Although certain technical and functional requirements are met, it is not comprehensive enough, and the results are still not ideal, and there are many imperfections. Researchers provide more comprehensive data and information on combustible solid powder, combustible gas, and combustible liquid explosion research, such as microscopic image information of explosion flames, data information of explosion intermediate products, uniform distribution of solid powder, uniform dispersion of liquid, etc. There is still a lot of room for improvement and development, especially in the rapid sampling and analysis of explosive gases and gas-solid-liquid multiphase mixed explosions.
