水系疊加
英文
palimpsest-
Creep analysis methods of high - rise buildings and large span buildings can only refer to creep coefficient method in bridge engineering or the method of degree of creep in hydraulic construction engineering under the present experiment conditions. in this paper, the incremental expressions of concrete creep and shrinkage strain when the initial computational age is not the same as the loading age are derived and corrected from the concept of concrete creep coefficient and the mean value theorem of integral and the principle of superposition. the differences of efficiency and accuracy of creep analysis between the finite element method with creep coefficient and the initial stress method with degree of creep are presented. this paper suggests that engineers should use the initial stress method with degree of creep to estimate the influences of creep on high - rise buildings and large span buildings on the basis of conceptual design

由於實際大型供水系統是非常復雜的動態非線性系統，在實際管網的運行中，受到多因素的制約和影響，各綜合因素作用疊加起來造成水流狀態極其復雜，使得很難以一個或幾個統一的顯式函數關系描述管網的工況。Due to this, it is important to improve the hydraulic power system and enable it to control the pressure change at the measuring points of the servo valve, thus to develop the syt - ii servo valve overlap hydraulic measuring platform and improve the processing quality of servo valve

在頻率域嵌入水印信息，是目前一種主流的嵌入演算法，在很多文獻中，都是通過量化音頻信號的ftf系數， dct系數，或者是dwt域的高頻系數。我們認為:在小波域內的近似分量（低頻系數）中嵌入水印能夠提高數字水印的魯棒性，通過量化嵌入水印的方法，將水印嵌入到近似分量中每個分段中最大值上，因為這樣對于同一個量化步長，量化對象的幅值越大，所疊加的「噪聲」就越小，從而提高了數字水印的不可感知性。Algorithm of terrain visualization by using scanning terrain map as texture ; 2. the simplified algorithm of view - point related multi - resolution terrain and the extended algorithm while its data are distributed like a band ; 3. the visual application of spatial query technique in the field of vector elements overlapping and the simulative evolution of flood
