| 摘 要： | 利用ＣＣＤ（ＣｈａｒｇｅＣｏｕｐｌｅｄＤｅｖｉｃｅｓ）摄像和计算机图像采集技术，测量了若干种自由火焰在形成及燃烧蔓延过程中的影像发展．可用几何函数和傅立叶函数分别描述火焰形成及燃烧蔓延过程中的影像发展．通过对有关回归函数数据的分析表明，火焰形成受燃烧规律控制，火焰波动受空气介入影响．

| Abstract: | The image of the growth and spread of the free flame were measured with CCD and computer image processing for several fuels. Two functions are used to describe different process, Geometry function to the flame growth and Fourier function to the flame spread, respectively. It is shown that growth of the flame is according with the combustion law, and the flame spread is affected by the air intervention after having analyzed the regression data. |
