cube edge 中文意思是什麼
cube edge
解釋
立方棱-
This arithmetic divides the wavelet coefficients of carrier image into 27 - classes by the background luminance, the texture and the edge mask character of visual system ; then after encrypting watermark image with magic cube transformation, the ycbcr model is employed, it embeds the watermark sequences in the carrier image with different intensity according to the coefficients " classes of carrier image in y channel
首先，將載體rgb圖像轉換到ycbcr顏色空間，然後提取亮度通道y ，將其進行小波變換，然後利用人眼視覺模型對載體圖象分解后的小波系數進行分類。其次，對有意義的水印圖像分別進行3次不同的魔方置亂，得到3個隨機水印序列。 -
Cubic having a volume equal to a cube whose edge is of a stated length
立方的，具有與一個邊長固定的立方體相同體積的 -
The first part deals with the construction of semisymmetric graphs and the second part classifies the edge - transitive regular coverings of the cube, whose covering transformation groups are iso - morphic to the elementary abelian p - groups
第一部分是關於半對稱圖的分類，第二部分是關于立方體邊傳遞的正則覆蓋圖的分類，其覆蓋變換群同構于初等交換p -群。 -
With this method, in the present thesis, we will classify all the connected regular covering graphs of the cube satisfying the following two properties : ( 1 ) the covering transformation group is isomorphic to the elementary abelian p - group ; ( 2 ) the group of fibre - preserving automorphisms acts edge - transitively
本文中，我們用同一種方法分類立方體的正則連通覆蓋圖，並且滿足兩個條件，覆蓋變換群同構于初等交換p -群且保纖維自同構群是邊傳遞的。 -
A parameter has been defined to account for both the heat transfer enhancement and pressure loss caused by different shapes and configuration of pin fin arrays and the optimization analysis shows that cube - shaped pin - fin arrays can be viable alternatives for pedestal cooling in a blade trailing edge
本文提出了一個強化換熱有效性系數來綜合考慮擾流柱換熱和壓力損失的效果，並用它對各種擾流柱進行了優化分析，優化結果表明方形擾流柱排在渦輪葉片尾緣區冷卻結構設計中是優先考慮的一種結構型式。 -
