  1. In chapter 2, a general digital watermarking frame is presented, including the generation, embedding and detection of watermark. in chapter 3, the concept of watermarking channel is presented, the modes of watermarking channel and image dct coefficients is proposed, the capacity of watermarking channel is evaluated by embedding watermarks to selected still image dct coefficients in direct spread spectrum. in chapter 4, a watermarking algorithms based wavelet multi - resolution is presented, by conjunction with human visual model, it keeps invisibility of watermark in host image and need not original image during detection

    數字水印是一種新的數字媒體保護技術，它是將特定的信息（如版權信息、秘密消息等）嵌入到圖象、語音、視頻等各種數字媒體中，以達到版權保護等目的，同時，這種信息對宿主媒體的影響不足以引起人們的注意且有特定的恢復方法，此信息對非法接收者應該是不可見的，本文主要對數字水印的一般框架，靜止圖象dct系數的理論容量，圖象水印的嵌入和檢測，數字媒體防篡改以及數字水印的攻擊等問題進行了研究，提出了兩個新的水印算演算法。
  2. This paper, in allusion to damage of expansion joint of bridge, introduces a sort of new structure of jointless device - semi - integral abutment jointless bridge, and establishes model of general structure finite element of this bridge, and in details analyses its qualities of stress. the model considers the interaction of superstructure - substructure - soil. resistance of the soil behind abutment adopts still soil pressure and elastic resistance when the temperature rising, but active soil pressure when dropping. analysis of qualities stress of bridge includes of action of dead load, car load, temperature load of season character. taking an 100m length pc semi - integral abutment jointless bridge as instance, the paper establishes the model of plane frame by applying large common software - anasys, and analyses it by elastane and large deformation to imitate character of stress and deformation of general bridge. at the same time corresponding models of finite element of joint bridge and integral abutment bridge are established, and unique stress and performance of structure of semi - integral abutment jointless bridge are researched by comparing and analysing character of three different models under same loading, and controlling factor of design and constitution are generalized. in conclusion, for semi - integral abutment jointless bridge, on one hand shear, moment and deflection of the main beam and axis force of substructure are approximate with that of joint bridge, and integral stifmess of structure is increased and damage of expansion joint is eliminated, on the other hand there is axis force in main beam, shear and moment of substructure are bigger than that of joint bridge. in all this type of jointless bridge has rational stress and is worth of application and popularization

    半整體式橋臺無縫橋梁計算模型考慮了上部結構-下部結構-土的共同作用；臺後土抗力升溫時採用靜止土壓力加彈性土抗力，降溫時採用主動土壓力；分析橋梁受力性能時考慮了結構自重、車輛荷載和季節性溫變荷載的作用。以一座橋長100mpc半整體式橋臺無縫橋梁為實例，採用大型通用軟體ansys建立平面框架模型，進行彈性、大變形分析，模擬全橋受力和變形特點；同時建立與此對應的有伸縮縫橋梁和整體式橋臺無縫橋梁有限元模型，通過三種橋型同步加載對比分析，研究半整體式橋臺無縫橋梁獨特的受力特點和結構性能，總結其設計控制因素和構造要求。通過本文研究知：半整體式橋臺無縫橋梁主梁的剪力、彎矩、撓度和下部結構的軸力與梁式橋相近，結構整體剛度增大，併除去了伸縮縫病害；但主梁增加了軸力，下部結構剪力、彎矩較梁式橋大；綜合分析是一種受力合理有實踐和推廣價值的橋型。
