  3. In this paper, chroma dc coefficients are selected as the carrier data because chroma dc coefficients are robust. also, alterable steps are used to select one part of the coefficients, so the watermark is imperceptible ; before watermark embedding, the watermark is divided into many parts, every part is individually embedded into one gop of the video, even if a gop is destroyed, the watermark can be extracted correctly, this methods promotes the robustness of the watermark ; in addition, in order to promote the security of the watermark, the user ' s id and password are used to generate chaos sequence by the chaos system which is created in this paper, later, watermark is mixed by the chaos sequence. also, the embedding position of the watermark bit is modified by one chaos sequence, so, unauthorized person can not extract or remove the watermark, since the embedding position is unknown

    本文認為，色度dc系數是魯棒性非常好的參數，因而選擇色度dc系數作為水印信息載體，同時，採用可變的步長選擇部分系數，保證了水印的隱形性；在嵌入水印時，本文採用水印信息「網格劃分」 、各子塊獨立嵌入視頻的方案，由於水印信息子塊是相對獨立的嵌入視頻中的每一相對獨立的圖組當中，即使某一圖組收到一定破壞，也能夠恢復水印信息，使水印的健壯性得到提高；此外，為了提高水印信息的安全性，在嵌入水印信息時，根據用戶輸入的id號和密碼，利用本文構造的混沌系統產生的混沌序列對水印信息進行變換，同時，對每一水印信息比特的嵌入位置也採用了偽隨機序列進行調整，這樣，未授權用戶不能提取水印信息，也難以擦除其中的水印信息，因為嵌入的位置是未知的。
  4. In order to resolve the question, in the thesis a simulation arithmetic of hydro - electrical system is put up. the equations of hydro - electrical system are divided to two parts, one of which consists of the differential equations of conduit system, hydro turbine and generator ' s rotator and is solved by characteristic equation arithmetic, the other of which consists of the differential equations of generator, magnetic system and grid and is solved by longge - kuta arithmetic or covert integrated arithmetic. through the alternative solving of the two parts, the simulation results of the large - disturbance transient could be abstained eventually

    為解決這一問題，本文提出了一種將水力系統和電力系統方程交替求解的水電系統聯合模擬演算法，即將包括輸水系統、水輪機以及機組轉子等部分的水力系統差分方程作為一部分，將包括同步發電機、勵磁系統以及電網等部分的電力系統微分方程或差分方程作為另一鄭州大學工學碩士論文部分，對前一部分採用特徵線法求解，對后一部分根據模型形式採用龍格一庫塔法或隱式積分法等演算法求解，這兩部分的求解過程交替進行，最終即可得到水電系統大擾動過程的模擬結果。
  5. The parameter in the xin ' anjiang model, imp, was extracted directly from above land use / cover data. another parameter, sm, in each subcachment and in each raster grid was obtained from the relation between sm and the ratio of forest land area to subcatchment area. thus, a semi - distributed hydrological model and a distributed hydrological model were established to analyze the effect of some parameters in xin ' anjiang on runoff process according to the spatial variability of land surface characteristics
