目前近海海洋模型大多从近海地形变化剧烈和细化浅水分层两个方面综合考虑,垂向坐标通常采用σ坐标变换,并且一般情况下均忽略了在坐标转换过程中出现的粘性-地形项。以POM海洋数值模式(princeton OceanModel)为基础,在对渤、黄、东海M_2分潮潮波的模拟中,具体分析了ε_u,ε_r,ε_s粘性-地形修正项对东中国海M_2分潮波系统数值模拟的影响。研究发现,加入粘性地形修正项后,可以增加模型中的耗散作用,使黄海西部M_2分潮模拟振幅减小约1～2 cm,渤海海区M_2分潮模拟振幅减小约4～5cm,在这两个区域潮汐振幅的减小会使得模拟结果偏离于实际观测结果,而在济州岛、长江口区域的模拟潮汐振幅约减小1～3cm,则会使模拟值更加接近于实际观测结果。从模型与90个验潮站的对比结果来看,粘性-地形修正项的作用范围相对较小,其整体影响并不很明显,但在某些特殊区域中该项对模型的输出结果有较为明显的影响。

利用基于普林斯顿海洋模式建立的胶州湾及临近海域潮汐潮流数值模型,结合胶州湾口走航式声学多普勒海流剖面仪(ADCP)测流资料,研究了胶州湾口的潮(余)流特征,并在潮流模型的基础上耦合建立了水质模块,模拟了胶州湾的水交换过程。考虑M2,S2,K1,O1,M4和MS4六个主要分潮,胶州湾口潮流场的模拟与ADCP观测数据吻合较好。外湾口水道上的潮流非常强,大潮期间观测到201 cm/s的峰值流速。团岛岬角的两侧分别存在一个流向相反的余流涡旋,两涡旋在团岛附近辐合,形成了57 cm/s的离岸强余流。整个胶州湾平均水体存留时间为71 d,平均半交换时间为25 d。胶州湾水体交换能力在空间分布上有很大差异:湾口海域最强,向湾顶逐渐减弱。湾内存在两个弱交换区,分别位于湾的西-西南部和东北端,水体存留时间多超过80 d,湾西局部水域最长达120 d,而半交换时间也大多超过40 d。潮流场的结构、强度,以及与湾口距离的远近是造成湾内水交换能力空间差异的主要原因。

在回顾国际上现有的潮流能资源估算方案基础上,提出利用三维潮流数值模式估算潮流能的思路,并在胶州湾进行了应用。基于普林斯顿海洋模式,建立了胶州湾潮汐潮流三维数值预报模型,对研究海区的潮汐和潮流做出了较为准确的模拟。数值模拟得到的胶州湾口最大可能潮流速度为2m/s,具有一定的潮流能开发潜力;湾口水道上多年平均潮流能蕴藏量为16MW,大潮期间的瞬时值和大潮周日平均值可分别达135和49MW.潮流资料时间序列的长度对潮流能储量的计算结果有较大影响。由于潮流现象具有强烈的时变性和多种周期,估算潮流能的平均储量应积累一年以上的资料为宜。研究表明,潮流数值模式能够提供高时空分辨率的三维潮流数据,有效弥补潮流实测资料稀缺的不足,因而可作为潮流能资源评价的有力工具。

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,283 new measurements from 899 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as heavy neutrinos, supersymmetric and technicolor particles, axions, dark photons, etc. All the particle properties and search limits are listed in Summary Tables. We also give numerous tables, figures, formulae, and reviews of topics such as Supersymmetry, Extra Dimensions, Particle Detectors, Probability, and Statistics. Among the 112 reviews are many that are new or heavily revised including those on： Dark Energy, Higgs Boson Physics, Electroweak Model, Neutrino Cross Section Measurements, Monte Carlo Neutrino Generators, Top Quark, Dark Matter, Dynamical Electroweak Symmetry Breaking, Accelerator Physics of Colliders, High-Energy Collider Parameters, Big Bang Nucleosynthesis, Astrophysical Constants and Cosmological Parameters. A booklet is available containing the Summary Tables and abbreviated versions of some of the other sections of this full Review. All tables, listings, and reviews （and errata） are also available on the Particle Data Group website： http ：//pdg. lbl. gov.

在3D模型检索领域中,高效的索引结构能提高检索效率。但是,3D模型库较为复杂,缺少有效的先验知识用于建立索引结构。作为一种非监督的技术,聚类分析技术则能在缺少教师信号的情况下揭示模型形状特征间的关系,使相似的特征值聚为一簇。因此,提出了一种依据聚类结果建立的索引结构ClusterTree。在介绍了ClusterTree的构造过程之后,分析了聚类算法结果对ClusterTree的影响,从而筛选出一种合适的聚类结果,为princetonShapeBenchmark建立索引结构。实验表明,该索引结构取得了令人满意的结果。
