    Abstract
  • The defining of effective acting time for pyrotechnic composition combustion underwater was put forward. The main problems of current methods for testing and processing the acoustic radiation characteristics of pyrotechnic composition combustion underwater and explosion underwater were analyzed. And then, based on Pulse Labshop software platform and experimental results, the effective acting time for pyrotechnic composition combustion underwater was obtained, with graphic slicing technique. This new method can be used to assess the effective acting time of pyrotechnic composition combustion underwater and explosion underwater sound source, and so on. It also provides a reference for the engineering application and performance evaluation.
