中文拼音 [shùnshíshēnsuō]
瞬時伸縮
英文
instantaneous companding-
The type of the base function of wavelet analysis is not single, while the ft has only the sine ( or cosine ) function or exponential function. wavelet transformation has the character of multi - resolution analysis. wavelet transformation can analyze the signal in any precision ( resolution ) at any part of time and frequency according to the different translation factors and dilatation factors
小波變換具有多解析度分析的性質,對應于不同的伸縮因子和位移因子,小波變換能對信號的任何時間(空間)段、任何頻率段進行任何精度(解析度)的分析,在非平穩信號(包括瞬間信號)的分析中具有很大的優越性,分析時,在信號的低頻部分具有較高的頻率解析度和較低的時間解析度,在高頻部分則具有較高的時間解析度和較低的頻率解析度,被譽為「數學顯微鏡」 。If there are high temperature gradient between cool liner and hot liner, compressive plastic strain appear at that transient time, which lead to gas film wall bearing high tensile stress at high temperature. high tensile stress is one of main reasons which destroy combustor
分析表明,起動過程中由於熱傳導滯后引發的溫度梯度可以導致火焰筒氣膜唇邊在起動瞬間發生較大的壓縮塑性應變,進而使得該區域在工作時承受較高水平的拉伸應力,高的拉應力會導致火焰筒萌生裂紋。
