It connects different factories or enterprises by the way of transmitting material flow or energy flow, to form industrial symbiosis networks by sharing the resource and mutual exchange by-products. Under this pattern,"by-product" of one producing process may be the raw material of another process. In order to explore material closed circular, energy conservation system and minimum discharge of the waste, it set up the circular pathway by imitating the natural circular system as"producer—consumer-- decomposer"in the industrial system.

This thesis contributes to geometry compression in the following aspects: Proposes a method of progressive spherical mesh parameterization based on local parameterization by directly projecting the deleted vertices to its neighborhood. Based on spherical mesh paramterization, an adaptive subdivision remeshing method by progressivly redistributing of sampling points is proposed, by this means, the main geometry information of the original mesh can be captured with only a small amount of samples, it can also be used in mesh simplification. By regarding attributes binded on mesh vertices as geometry signals and transferring them onto a uint sphere by means of spherical mesh parameterization, meshes with different attributes are compressed with spherical wavelet successfully with high compression rate. As a kind of lossy geometry compression technique, two mesh simplification algorthimes are also presented in this thesis.

归纳起来，本文的主要贡献有：提出了以直接投影局部参数化方法为基础的网格累进球面参数化方法；在网格球面参数化方法的基础之上，提出了一种基于累进优化布点方案的网格细分采样方法，该方法可以用很少的采样点就可以捕获到网格的主要特征，因此我们也将其用于后面的网格简化工作当中；通过将网格顶点上定义的各种属性看成几何信号，并以网格球面参数化为手段将几何信号迁移到单位球面上，从而成功地实现了用球面小波对各种几何信号的压缩；作为一种有损压缩方法，本文还提出了基于统一距离的网格简化算法和基于重采样的网格简化算法。

在液冷散热器的研究中，主要通过对液冷吸热盒设计不断地改进(使吸热盒底部的材料从铝合金变为纯铜材料，其整个体积有所变大，但其散热效果明显变好，且密封性得到了极大地加强)，综合地运用换热器中肋片的壁面温度调节作用产生的散热效果(肋片材料优良的导热性，快速地扩散了热量：肋片较大的与流体接触的表面积，使传热更加充分，对流热阻大大减小；再利用风扇对肋片上的热量进行吹散)，利用性能优良的压电陶瓷泵(该泵机电性能稳定，具有无电磁干扰、体积小、噪音小、外型轻薄、重量轻、低能耗。、高扬程等优点。)代替机械泵作为驱动源，搭建了整个散热系统。

F〓 of transgenic allotetraploid fish containing"all-fish"transgene——pCAgcGHc was obtained respectively by inbreeding and gynogenesis. Positive rate of pCAgcGHc detected by PCR was 90％ in F〓 of transgenic allotetraploid fish produced by inbreeding, while most F〓 of transgenic allotetraploid fish produced by gynogenesis showed diploidy measured by flow cytometer. The results above imply that developing the pure line of transgenic allotetraploid fish through inbreeding is feasible, but the operation should be modified if gynogenesis is introduced.

Since the dismutation of superoxide radicals by SOD is a reaction that is rate-limited by diffusion and enhanced by electrostatic guidance, all these structural features may be related to GP-MnSOD's high catalytic activity: first, Lys38 may increase the effective enzyme-substrate association rate by enhancing the electrostatic gradient at its substrate channel; second, an excess of acidic over basic residues makes the negative surface potential of GP-MnSOD more larger than those of other known MnSODs. This may enhance the reaction rate by reducing futile collisions of superoxide radicals with GP-MnSOD's surface.

因此，GP-MnSOD的上述结构特征可能与GP-MnSOD的较高酶活有关：首先，Lys38增加了底物通道口的正静电势梯度，从而可能促进了GP-MnSOD的活性中心与底物的有效结合速率；其次，GP-MnSOD表面覆盖的过量酸性残基使得它比其它MnSOD在底物通道以外的蛋白表面更多地被负静电势所覆盖，这可能有效地减少了超氧阴离子与GP-MnSOD表面的无效碰撞，从而提高了反应速率。
