| 中文摘要: |
| 利用时频分析方法对在灭火介质作用下的火焰温度波动进行了分析。获得了火焰点燃到被扑灭整个过程的时频分布谱图,由此得到温度波动频率随时间的变化情况。这种频率变化从一个方面反映了火焰的稳定性的变化。 |
| 英文摘要: |
| Temperature fluctuation of flame under extinguishant exertion is analyzed by time frequency analysis method. Spectrogram of time frequency distribution is obtained from ignition to extinction of flame. Frequency change of temperature fluctuation along with time appears in this distribution. The frequency change reflects stability change of flame from an aspect. |
