| 中文摘要: |
| 本文通过对数字时间序列分析中最大熵谱法的研究，给出了分辨率比传统谱方法高得多的功率谱，并在扬沸火灾监测预报方面建立了扬沸前兆噪声的工程识别模型。本文第一部分讨论了改进的最大熵谱法，并通过研究热混合层的脉动温度和湍流撞击射流的脉动速度的谱结构，验证了该方法的可行性。 |
| 英文摘要: |
| Through the rebearch of maximum entropy spectrum method of time series analy-sis, the power density spectrum with much higher resolution than the classical spectrummethod can be obtained and the engineering indentification model of boilover premonito-ry noise was also founded to diagnose and predict the occurrence of boilover,The in-proved maxlmum Entropy spectrum method was di5cussed in part I of this paper,and itsfeasibility was proved by studying the spectral structure of the thermal mixing layer andturbulence impinging jet. |
