When there are struts at the divergent parts of inlet , the total pressure recovery coefficients and the kinetic energy coefficients of inlet decrease , and the flow distortion index increases obviously 當進氣道擴壓段有側(cè)向支柱存在時,進氣道總壓恢復系數(shù)和動能系數(shù)均有所降低,而流場畸變指數(shù)則顯著增大。
A method is put forward which selects modal dofs in a few points according to element strain energy coefficient . therefore , the selected modal dofs in a few points usually have large amplitude , which is conducive to be measured and the network training 在選取少數(shù)節(jié)點的振型分量用于網(wǎng)絡訓練時,提出根據(jù)單元應變能系數(shù)的大小來選擇節(jié)點,這些節(jié)點一般來講在振動中振幅較大,易于實測和用于網(wǎng)絡訓練。
3 . utilizing the hvs and the characteristic which integer wavelet analyzes the high - frequency coefficient to express the image detail , proposed the definition of energy coefficient . according to the sub - blocks from different groups , the computed energy coefficients were different 3 .利用人眼視覺模型和整數(shù)小波分解后高頻系數(shù)表示圖像細節(jié)的特性,提出了能量系數(shù)的定義,根據(jù)不同組的子塊,計算出的能量系數(shù)是不相同的。
