According to the function of distributed emulator, optical information processing and image multi-object tracking system, the following three aspects were emphasized in this dissertation. Firstly, a vast virtual terrain, ground radar models and canyons were created for the distributed emulator with modeling software Creator. The radars were driven to scan during emulating and the real time terrain code was sent to Radar module. Secondly, an optics channel simulating the optics camera of a virtual aircraft was implemented with simulating software Vega. The 2-D information got from the channel was translated and sent to multi-sensor information fusion system as an optics information source. Thirdly, the dissertation studied some motion estimation methods and analyzed the factors which influence the speed and the precision of the block matching algorithms. Then an improved block matching method was proposed for image multi-object tracking system and applied in the system combined with frame difference method.

In calculation, it was assumed that nozzle flow was frozen, and convective and radiative heat transfer from gas to nozzle wall was considered. Governing equations were discretized with second order upstream scheme and radiative heat transfer equation was solved with Discrete Ordinates method.

在计算中，假定喷管流动为冻结流动，考虑燃气向壁面的对流换热和辐射换热；采用二阶迎风格式离散控制方程，采用DO模型离散求解辐射换热方程，水蒸气的吸收系数根据Leckner公式计算。

Two, the synopsis expatiates to play development, important position and newses that sow the room dialogue the news anchor should enhance the various ability to better control to play to sow room dialogue this kind of new form.

二、简要的阐述了演播室对话的发展、重要地位以及新闻主播应加强多方面的能力来更好的驾驭演播室对话这种新形式。

In many reasons of causing cracks, only a few studies are reported about the influence of concrete shrinkage and creep on cracks for its computational complexity. If any, most calculations are only based on the two-dimensioned finite element model. So it's significant that how to analyze the spatial effect of concrete shrinkage and creep by utilizing large software.

在众多的开裂原因中，混凝土收缩徐变的影响，由于计算的复杂性，这方面的研究报道很少，而且大部分的计算也只是基于二维杆系有限元模型，因而如何利用大型软件进行考虑混凝土收缩徐变的空间效应分析，十分有意义。

In the aspect of structure line detection, the main idea is to separate the roof structure lines into two parts, one is for external contours and the other is for internal structure lines. The external contours were extracted using Hough transform and other geometric conditions. The internal structure lines were extracted by any two adjacent roof faces intersecting each other. Finally, the two kinds of structure lines were combined to construct the roof shapes.

而在结构线的侦测方面，主要将屋顶结构线分为两个部份来进行，第ㄧ为外部轮廓线，萃取的方式是利用霍夫转换及其他附加几何条件来进行；第二为内部结构线，萃取的方式为利用相邻屋顶面的交会来获得；最后再将此二种特徵线合并在一起，进而重建完整的屋顶面形状。

On the contrary, the similar folk art, a song-and-dance duet is flourishing and gradually gains acceptance nationwide. It is attributed to various reasons.

反之，与&二人台&有不少相似之处的姐妹艺术&二人转&却异常红火，并日渐受到全国观众的认可，其原因是多方面的。

In this image I have used 13 lights: 4 omni lights as ambient lighting, 2 to highlight the form of the engine, 3 spotlights to highlight the back of the engine, 3 highlight to stress the specular and the greasy effect on the shell, a spotlight behind the snail neck for the sub surface scattering, in addition to the sun with area shade and the sky with a HDRI with an atmosphere similar to the photograph of the road for the global lighting I have used a surface with an asphalt texture for the floor and the yellow lines only to be reflected on the engine and to add some radiosity to the snail body and shine.

在这方面的形象，我用13个灯： 4全方位的灯作为环境照明，二要强调形式的引擎， 3射灯，以突出后面的引擎， 3突出强调，镜面和油腻的作用，对蚬壳，一聚光灯背后的蜗牛颈部为小组表面散射中，除了太阳与地区的树荫和天空与hdri与气氛，类似照片的道路，为全球照明，我用了一个表面上与一沥青纹理为楼和黄线只反映对发动机，并添加一些辐射，以蜗牛身体和服务。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
