In chapter 5, the concept of zero-span tension known in papermaking area is for the first time introduce to wood science area to explore in-tree variation of longitudinal tensile strength of tracheids and its main influencing factors. In chapter 6, composite micromechanics and classic laminated theory are used to make a comprehensive and detailed analysis of the main influencing factors of mechanical properties of tracheids cell wall. Some experimental results acquired in the foregoing chapters are explained successfully. Results were summarized as follows: Mechanical characteristics of wood at micron scale: 1 At micron scale, the longitudinal mechanicai behavior of wood microtome section differs greatly from that of wood with normal size.

But verification of MOND, like dark matter, has suffered from the fact that it manifests itself only on very large scales, comparable to the size of galaxies, and so is not amenable to local tests.
可是 MOND 同暗物质一样,都受到了实践的限制。它同暗物质一样,要在可以与星系尺度相比拟的、非常巨大的尺度上才能得到证明,也不服从局部的试验。

So in the master class, he encouraged all the teams should not be limited by the existing site condition. The projects should not only solve the problems but also give the vision of development to the future. He considered that the projects should beyond the local scale of city fabric. The projects should have monumentality and publicness but not just become the local community centers.

First, the proposed scheme uses contourlet transform to extract multidirectional and multiscale texture information, and then obtains the feature points invariant to the affine transformation from the low and middle directional subbands by Harris-Affine detector. Second, the feature regions are adaptively computed by the feature scale of the local structure and normalized by U transform. The watermarking is embedded adaptively in those characteristic regions which are normalized. Finally, by vector quantization, several copies of the watermark are embedded into the no overlapped local feature regions in different directional subbands.
首先,用Contourlet变换提取出多尺度、多方向的纹理信息;再用Harris-Affine检测算子从变换域的中、低频方向子带中提取出仿射不变特征点,结合自适应局部结构的特征尺度确定特征区域,并用U变换对其归一化处理,水印就自适应地嵌入到归一化后的区域中;水印嵌入采纳矢量量化的策略,将水印信息重复嵌入到不同方向子带、多个不相交的局部仿射不变特征区域。
