Thecharacteristic and different using limit of both optimization criteria method andmathematics programming method are all analyzed in this paper. OC algorithm and theseries MMA algorithm based on SIMP approach are deducedand used for the topology optimization problem of continuum structure. MMA algorithm hasa bad convergence but it has a high computational efficiency, while GCMMA is excellent onconvergence and stability with bad calculation efficiency.

优化求解算法是拓扑优化问题求解的核心和关键，本文系统分析了适用于离散结构和连续体结构优化的优化求解算法，重点讨论了 OC 算法和 MP 算法，分析比较了不同算法的特点和适用范围，推导了基于 SIMP 理论的优化准则法和 MMA 系列算法，并将MMA 系列算法应用于连续体结构拓扑优化问题的求解。

Originally from Saudi Arabia's Eastern Province (Hofuf in Al-Hasa oasis, the centre of Saudi agriculture), the family first made its fortune through trading dates to India, and became enormously wealthy during the Gulf 's pearling boom - famous for being Arabia's first millionaires (in the 1920s and 30s they were the richest family in Arabia).

来自沙特阿拉伯东部省（胡富夫在哈萨绿洲，该中心的沙特农业），家庭的财富首次提出通过交易日期到印度，并成为巨大的富裕在海湾的珍珠繁荣-著名正在沙特阿拉伯第一百万富翁（在1920年代和30年代，他们是最富有的家庭在沙特阿拉伯）。

It hasa small resource footprint allowing it to run on relatively low specification machines.

使一小的资源足迹允许它在相对低的规范上运行用机器制造。

For compact hypersurfaces and highcodimension compact submanifolds initial data respectively, we prove that the flow hasa smooth solution for all time under almost optimal conditions. Those conditions arethat the second fundamental form on the initial submanifolds is not too large, the exter-nal force field, with its any order derivatives, is bounded, and the field is convex with itseigenvalues satisfying a pinch inequality.

我们分别对紧超曲面初值和高余维紧子流形初值证明了当初始曲率比较小，并且外力场除了要各阶导数一致有界外，还要满足凸性条件以及特征值的一个pinch条件时，这种热流的光滑解长时间存在。

在本研究中，我成功的藉由genomic-PCR获得 Streptococcus zooepidemicus hasA的转录区域片段，并选殖於大肠杆菌载体，并在 E。

Longquan celadon current more than 130 workshops, employing morethan 5,000 multi-family practiced on a cottage, family-orientedtradition, family members for the technical backbone, currently hasa national master of Longquan celadon Xu Zhaoxing, Jaap de HoopMan, Mao is Satoshi, Zhang, Shaobin.

龙泉现有青瓷作坊130余家，从业人员5000余名，多以家庭作坊式生产、家族式传承为主，家庭成员为技术骨干，目前龙泉青瓷拥有国家级大师徐朝兴、夏侯文、毛正聪、张绍斌。

A structured grid partitionfor full scale coal fired tangential utility boiler has been given in this paper. It hasa small amount of grids and can decrease false diffusion effectively as it is inagreement with fluid flow direction. Accurate simulating results can be gainedwith the grid partition. Inverse flows are captured near the wall at four corners incombustion simulating through the above grid and temperatures simulating agreewell with them measured.

对于大容量四角切圆锅炉的数值模拟，本文给出了一个可以有效减小伪扩散、流体流动方向与网格线方向一致、数目较少、计算精度较高的结构网格，该网格的数值计算结果清晰得捕捉到了四个角向火侧和背火侧靠近壁面处的小回流，而且计算温度与炉膛温度实测值较好的吻合。
