The multi-stage Tabu Search fits for the situation where the problem has middle size, the quality of solution is important, and the speed is not restricted too much.(4) The combined algorithm which shares the advantages of HR and TS—high speed and high quality—is the most practicable one for middle-scale problems.

通过仿真实验对分枝定界算法、基于运行的启发式算法、多阶段禁忌搜索算法和组合算法进行一系列的对比研究，得出以下几点结论：(1)分枝定界算法只适用于问题规模小且对计算时间要求不高的场合，它是一种最优化算法；(2)启发式算法适合于求解大规模问题，尤其是实际应用中遇到的大型问题，对计算时间要求较高而对解的质量只要满意即可。

The Café of the simple inn where they stayed was the meeting-place of the notabilities of the little city; the Sindaco, the avvocate, the doctor, and a few others; and among them they noticed a beautiful, slim, talkative old man, with bright black eyes and snow-white hair—tall and straight and still with the figure of a youth, although the waiter told them with pride that the Conte was molto vecchio—would in fact be eighty in the following year.

那天早上，年轻夫妇待在小旅馆的咖啡厅里。这个咖啡厅是小城名流的聚会场所：市长、律师、医生以及一些其他名人常聚在这里。在这些名流中，年轻夫妇注意到了一位头发花白的老人。老人目光矍铄、面容俊秀、身材细长，十分健谈，一点也不像咖啡厅的侍者自豪地说的――伯爵来年即满80岁了。伯爵虽年事已高，但个儿很高，身形也像年轻人一样――腰板儿很直。

The low corona can also be monitored to some extent from mountain-top coronagraphs, such as the K-coronameter of the High Altitude Observatory onMauna Loa, Hawaii, but even that instrument occults the lowest corona, and its images are relatively noisy and show little detail.

较小的日冕也能被高海拔检测站检测到，例如夏威夷的高海拔天文台K-coronameter，但对于极低日冕，其图像分辨率较低。

Any high Re number flow over bodies consists of three basic flows: the flow with convection-dominant in all spatial directions, the flow with convection-diffusion competition in all directions and the flow with convection-dominant in part directions and convection-diffusion competition in part directions, which is called the interacting shear flow; the features of the three basic flows are different; their simplest conservation equations, i.e. the Euler equations, Navier-Stokes equations and diffusion parabolized NS equations, have different mathematical characteristics; there is a great disparity in domains of the three basic flows and the domains of NS equations are very small. Therefore, adopting Euler-DPNS-NS equation system to analyze and compute high Re number flows over bodies is a logical approach. There exists a mutual examined-complemented relationship of this approach with the usual one of adopting only NS equations.

主要内容如下：（1）高Re数绕流包含3种基本流动：所有方向对流占优流动、所有方向对流扩散竞争流动和部分方向对流占优部分方向对流扩散竞争流动，3个基本流动的特征彼此不同且在流场中所占领域大小彼此相差悬殊，NS方程区域很小，它们的最简单控制方程组Euler、Navier-Stokes和扩散抛物化NS方程组的数学性质彼此不同，因此利用Euler-DPNS-NS方程组体系分析计算高Re数绕流流动就是一个合乎逻辑的选择，该法与利用单一NS方程组的常用方法可以彼此检验和补充。

The shoaling wave height is related to wave steepness. Comparing with wave theories the shoaling coefficient of small amplitude wave theory_ which is not related to wave steepness, disagrees with experimental reset. The experimental result has the trend with Stokes third order shoaling theory, but Stokes wave theory overestimates the shoaling coefficient .

波浪之浅化波高与波浪尖锐度有关，微小振幅波理论中浅化波高与波浪尖锐度无关与实测值不符，实验结果在定性上与Stokes波三阶浅化理论有相同之趋势，但在定量上实验之浅化系数较小，理论值有高估的现象。

In research area, the widely varying substrata has the thin effective thickness, low permeability, scattered distribution and obvious heterogeneity .Controlled by sedimentary facies, it has obviously corresponding relationship with the sedimentary facies. For this reason, substrata with thick effective thickness have better permeability.
