有形状的

The fractal theory is discussed used in urban spatial morphology. From the psychologic cognition mechanism aspect, according to cognitive superincumbent process, the indexes system and research frame for quantitatively descriptive urban spatial morphology are constructed.

基于以上研究，笔者探讨了网络分析和特征值分析中的主要指标，即对线状要素描述的主要指标有：方向均值、关联矩阵、邻接矩阵、回路数H、β指数、α指数、γ指数等，对面状要素描述的指标有：圆形率、紧凑度、形状系数、标准面积指数、放射状指数等；并探讨了分形理论在城市空间形态研究中的应用，在此基础上，从心理学的认知机理出发，按照自上而下的认知过程构建了定量描述城市空间形态的指标体系和研究框架。

Based on 3D steady and incompressible NS equation and kε turbulent model, the aerodynamic performance of three different design options of 160 km/h container flat wagon was analyzed and compared using finite volume method. The three design options are as follows: the first design option has no headwall and the side surface of side beam is flat; the second and the third both have headwall and high side beam, and the side surface of side beam of the second is obtuse, while the third is cambered.

摘 要：基于三维、不可压、定常 N S 方程和 k ε双方程湍流模型，采用有限体积法对3种不同设计方案在运行时速为160 km/h的集装箱专用平车在有、无横风情况下的气动性能进行分析与比较，其中：方案一的平车无端墙，侧梁侧面平直；方案二和三的平车均加有端墙，且侧梁加高、侧面形状分别为钝形和弧形。

The enlarged showy calyx-lobes in Mussaenda are good examples. The calyx-lobes, so called calycophylls, are mostly leaf-shaped, but have bright color, papillate epidermis, and loose mesophylls, features generally only found in petals. In higher eudicots, floral organs are typically arranged in four different whorls, namely sepals, petals, stamens and carpels.

自然界中有钗h植物以一整个花序替代一朵花作为传粉的单位，而在这样的花序中常常会有某些构造花瓣化来替代原来花瓣的弁遄C玉叶金花是一个非常有趣的例子，这一属的植物常具有膨大的花萼裂片，其形状类似叶子但多具有鲜艳色彩，且细胞形态及细胞排列均相当类似於花瓣，在弁鄐W一般均认为与花瓣无异。

Compared to the sample without ultrasonic treatment, it was found that, for AZ31 magnesium melt alloy treated by ultrasonic, the refined grain size and the inproved distribution of grain with its shape of oval-shaped or spherical can be obtained, and the precipitation inside Al matrix was inhibited The Mg17 Al12 precipitates distributed mainly along the grain boundary and hardness was improved remarkedly.

通过对铁合金AZ31进行熔体超声处理发现，处理后试样的晶粒较未进行超声处理的试样有明显细化，分布均匀程度提高，形状呈椭圆状或球状，合金元素Al在晶粒内的析出被抑制，Mg17Al12第二相的析出主要集中于晶界，硬度有明显提高，并且通过试验确定出了最佳处理功率和时间，为超声波在铸造生产中的应用提供了依据。

The size, shape and exine ornamentation,verrucose,exine thickness,and the size of lumina in pollen grains are of great significance in the systematics at species level of the genus Calamus.

花粉的大小、形状、外壁纹饰、外壁是否有突起，外壁厚度和网状纹饰网眼的大小，对于省藤属的种级分类有较大的意义。

The architecture of the houses is thought to date back to the 13th century AD. Built out of volcanic rock and ash, the small houses have been eroded by the elements over thousands of years.Today the houses are shaped like cones and pyramids, with some measuring 60 metres.

房子的建筑风格被认为要追溯到13世纪，房子以火山石及梣木建造，这些小房子存在数千年的光景下，有了被大自然磨损的痕迹，现今的房子都是圆锥和金字塔的形状，有一些高达60公尺。

There is enormous variety in size, shape, texture, bloom and color of these bromeliads. Many of these unique plants undergo a dramatic color change as they prepare to bloom. Some have a very luscious and unequaled fragrance.

它们的规格，形状，结构，花朵的颜色是多种多样的，并且开花的时候植株的颜色还会有巨变，有一些品种还带有浓烈的香味。

For the aqueous luminol solution, three absorption bands with maximum. adsorption wavelength λ max 220.7、294 4 and 351.5nm respectively have been detected, with the exception of a little hyperchromic effect, the absorption spectrum contour of the solution cavitated by an ultrasound with a frequency of 1.45 MHz has been certificated to be unchanged.

luminol水溶液的吸收光谱有3个吸收带，它们的最大吸收波长分别是220.7nm、294.4nm和351.4nm，超声空化作用后主要呈弱增色效应，但其吸收光谱的基本形状无明显变化。luminol-NaOH水溶液经超声空化作用后也有较弱的增色效应和减色效应，但不论是否经历超声空化作用，其吸收光谱都与luminol水溶液的吸收光谱相似。

However, there is still a problem with the plastic/rubber grommets being used where the socket screws into the base of the lamp. On all except 76117 and 76320, the grommet is coming loose and traveling down the length of the cord, so there is metal rubbing directly against the cord. On some, it appears that the grommet isn't the right shape or the right size to fit properly, so while it may sit in the opening correctly for a while, it doesn't stay there.

不管怎么样，这里还是有一些问题出现在当我们把灯装进这些塑料或橡胶的螺丝孔子时，所有的产品除了76117和76320，在这个装配环节上都出现了滑丝和螺纹太短的现象，所以这里会出现金属和橡胶件配合出现不适合的现象，同时有一些出现螺纹形状不对的或都是尺寸不对，以至于装不进去。

It was like the big platters of fruit and meats that they brought out and set before me.

这就像是他们拿出来并放置在我面前的大盘水果与鲜肉，有一种近乎于疯狂的杂乱感，又有一种满足于自我的丰足感，洋溢着各式各样的色彩与形状，如醇酒般甜美无比。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
