但是，以往的研究中，枝晶组织和枝晶生长这两个密切相关的问题一直被分隔开来进行研究；在稳态枝晶生长理论研究中，由于枝晶界面真实形状问题没能解决，迄今为止，比较有希望的理论模型都是建立在"枝晶界面的旋转抛物面假设"这样一个早已被认定不是枝晶界面真实形状的"基础"上。

Based on the structure of a non-tracking internal-concentrator solar PV-thermal tube collector and the absorber design requirements, the optical design for the compound parabolic concentrator with half cylinder absorber is proposed to improve the solar energy efficiency. Matlab software was used for the optimization and simulation of the concentrator curve and shape. The curve equation of concentrator for maximum incidence of light of the collector was obtained; and the installation locations for CPC/half cylinder absorber and the necessary CNC processing parameters were optimized.

针对非跟踪内聚光光电－光热复合管的结构及接收器的设计需求，对管内具有特殊形状的半圆柱接收器的复合抛物面聚光器进行了光学设计，并利用Matlab软件对聚光器曲线和形状进行了优化与数据仿真，得到了光热复合管能够得到最大入射光的聚光器的曲线方程、安装位置以及供数控机床加工所需的参数，给出了不同入射角的光线和光强分布图，提高了太阳能的利用率。

In the field, the popular methods include: using Kalman filter or Particle filter to estimate motion, estimate the optical flow, utilizing the active contour model, the active shape model and the deformable template to tracking the objects, and using the Geodesic active contour model or Geodesic active region model which based the partial difference equation method and level set frame.

在该领域常用的方法有利用Kalman滤波及粒子滤波进行运动预测，通过计算光流评价目标运动，利用活动轮廓模型，活动形状模型，可变形模板等主动形状模型方法以及测地线活动轮廓模型，测地线活动区域模型等基于偏微分方程的方法来跟踪目标运动。

The results showed:among the 7 isolates, five isolates of HY3、GY1－3、ZJ1－1、HP1、FC3 had same colony shape, irregular shape, liquidlike, slimy, opacity with smooth surface;the other two isolates had same shape, irregular shape, dry, opacity with coarse surface. By inoculating eucalyptus with the 7 isolates, the plants were infected apparently, and the young plants of eucalyptus in control experiment with tap water were not infected. By cultivating eucalyptus cuttings with the bacterial suspensions without EPS, the incidence of disease was very distinct,but compared with the former bacteria suspension,the incidence of disease has decreased at different degrees. By screening out two isolates of strong pathogenicity and two isolates of weak pathogenicity from the 7 isolates,making the bacterial suspensions with them to inoculate the young plants of eucalyptus, two treatments of cutlings and ramets with rats were set with 5 repetitions in every treatment, the results of data analysis showed: for the cutlings, the bacterial contents in upper and middle parts、upper and lower had significant difference;for ramets with roots, the bacterial contents in upper, middle parts, lower had significant difference between each other; For both the cutlings and ramets with roof, the bacterial contents in xylem and phloem had significant difference. The interaction between vertical and horizontal parts for the bacterial content had significant difference. For the two isolates of HY3 and 93B which were screened out at last,their activities of the cellulase were: 1.955ug/ and 1.288ug/ respectively, and had significant difference; the activities of pectase were: 1.325 ug/and 1.24ug/ respectively, and had no significant difference. The content of EPS extracted from the two isolates of HY3 and 93B was very different: 7.08x10-8ug/cell and 5.17x10-8ug/cell.

结果显示：7个菌株中，其中5个菌株HY3、GY1－3、ZJ1－1、HP1、FC3的菌落形态相同：不规则形状、流体、粘性、不透明、表面光滑；另外2个菌株93B、GN1菌落形态相同：不规则形状、干燥、不透明、表面粗糙；用7个菌株接种剪根桉树苗，发病情况非常明显，而自来水对照实验中桉树苗却不发病；无EPS菌悬液培养桉树剪根苗，发病率也很明显，但是相比原菌液，则发病率有不同程度的下降；从7个菌株中间筛选出来2个强致病性菌株和2个弱致病性菌株，用它们配制菌悬液培养桉树苗，设置剪根和不剪根两个处理，每个处理设置五个重复，数据分析结果显示：对于剪根苗，上部和中部、上部和下部的含菌量有显著的差异，中部和下部含菌量差异不显著；带根苗，上部、中部、下部含菌量彼此之间差异显著；不管是剪根苗还是带根苗，木质部和韧皮部含菌量之间的差异都非常显著；上中下与木韧交互作用中，含菌量差异非常显著；最后筛选出来的强弱2个菌株HY3和93B，它们的纤维素酶活性分别为：1.955ug/和1.288ug/，具有显著的差别；果胶酶的活性分别为：1.325 ug/和1.24ug/，没有显著的差别，而且HY3和93B两个菌株细胞分泌的胞外多糖的含量差异很显著，分别为：7.08×10-8ug/cell和5.17×10-8ug/cell。

Measurement began our might: Forms a stark Egyptian thought, Forms that gentler phidias wrought.

衡量开始了我们的力量，——个典型的埃及人把形状思想，温和的费迪阿斯做出的形状。

"The shape is closer to that of Crete than Cyprus although, to be fair, the designer does seem to have taken some artistic license with the other countries too," said Peter Geoffrey, a Dublin philatelist

都柏林集邮家彼得·杰弗里说：它的形状看上去不像塞浦路斯而更像克里特岛，尽管公平的说，邮票设计者确实也从艺术角度对其他国家的版图形状做了一些修改。

Famous people who believed in phrenology included Queen Victoria of Britain, the American poets Edgar Allan Poe and Walt Whitman.

但面代科学证明，人的头骨的形状与大脑的形状并不相符，也没有证据证明人的性格与大脑的特定区域相关。

The most common colors are black and white, grey and white, copper-red and white, and pure white, though many individuals have blondish, or piebald spotting. Striking masks, spectacles, and other facial markings occur in wide variety.

最常见的颜色是黑白，灰白，铜红和白，以及纯白，但也发现过金色的和有斑点花纹的，以及各种各样引人注目的口罩形状、眼镜形状等样式的脸部花纹。

Pig iron is useful because it can be formed into solid, heavy objects or objects with unusual shapes.
