• The chemical reactions in the flame area are very complex . it is very difficult to measure the number density distribution of the particles ( atoms , ions and molecules ) , so the relative intensity method is employed
  由于固体推进剂燃烧区内发生的化学反应非常复杂,直接测量火焰区内的粒子(原子、离子以及分子等)数密度比较困难,因此选用相对强度法来进行计算。
• It includes the following aspects : adopting the partial differential equations and neighborhood average smoothing methods to reduce image noises . mapping the rgb three - color and gray scale histogram to study - 3 - the relationship of flame features and temperature field distribution . the methods of calculate important parameters about the average gray value , the flame area and the flame shape center coordinate are given
