透视

The knowledge of vanishing point is an important step for oncoming camera self-calibration and 3D reconstruction. Under perspective projection, lines paralleling each other in space will converge to a point called the vanishing point in the image plane.

在人造建筑物的图像中，存在着许多空间上相互平行的直线，这些直线经过透视投影后将在成像平面上相交于一点，称为消隐点。

Keywords: Perspective ; Vanishing Point ; Measuring

透视； 消失点；量点

Based on the vanishing point received from the invention, the file image can be accurately and quickly executed with perspective and correction.

在由本发明获取的消失点的基础上，可以准确而快速地对文档图像执行透视校正。

The famous story of ancient blacksmith couple, Gan-jiang and Mo-xie , has been reinterpreted and deduced since the dynasty of Eastern Han, with its literary value profoundly embodied. This paper aimed to:(1) analyze its heritage and development in each era, so as to c翠¤truct the vertical veining;(2) investigate its spreading through space and various forms, so at to expand its horizontal connection; and (3) observe human mind behind the cultural context with insights into the internal meaning of the storyline.

论文摘要：「干将莫邪故事」是众人熟知的铸剑故事，从东汉到近代，故事不断被重新诠释及演绎，体现可贵的文学生命价值，本文的撰写主旨即在：一、剖析故事在各时代的流传及演变，以建立其纵向发展脉络；二、探讨故事的空间传播及不同的表现形式，以拓展故事的横向联繫；三、藉故事的内在意义透视人类的文化心理。

Objective To evaluate the efficacy and safety of the method of holding wire temporarily for occlusion of ventricular septal defect. Methods 32 patients with VSD diagnosed by transthoracic echocardiography and left ventriculography were suitable to interventional therapy.

编者按：封堵器置入时保留导丝的方法封堵VSD安全、高效，特别适用于难度较大的VSD的封堵，该方法简化了更换封堵器时需重建轨道的程序，缩短了操作及透视时间，减少了并发症的发生，手术成功率高，疗效可靠，值得推广。

All patients underwent left ventriculography before catheter closure, and the closure was monitorded under the transthoracic echocardiography and fluoroscopy guidance.

封堵术前常规行左室造影，在经胸超声心动图及透视监测下通过建立股动静脉轨道、经右心系统释放封堵器。

During this period, the respective removal of chemical oxygen demand, suspended solid, ammonion NH4(superscript + reached around 86%, 77%, and 91% respectively, while the F/M was around 0.12 kgCOD/kgMLSS-day. The effluent was clear, highly transparent and odorless. The microscopic observation showed that amount of Ciliata, such as Vorticella Convallaria, Vorticella Alba, and Vorticella Microstoma, could be found in the reactor's supernatant.

以显微镜观察微生物相时有固著型纤毛虫类出现，所谓活性污泥指标微生物，如白钟虫、钟形虫、小口钟虫、甚至旋轮虫等原生动物，污泥胶羽能凝聚成团、颗粒大、结构紧密、沉降性佳、处理水质清澈、透视度佳、无臭味。

The trend is central vowel , and it will lead to the simplification of "RuSheng" rhymes construction.

这种对微观的正在进行的音变研究，或许可以透视宏观的历史上已成音变的原理和原则。

For example, we wanted users to be able to be able to change sorts and filters to better understand data they were looking at without leaving the context of the browser. We wanted users to be able to adjust PivotTables to see exactly they data they wanted to see in order to make better business decisions, again without leaving the context of the browser. We wanted users to be able to set parameters to perform what-if analysis, again from within their browser.

例如，我们希望用户不必离开浏览器页面就能变换排序和筛选来更好地理解他们正在查看的数据；能调整数据透视表以确切地看到他们想要的数据以便于做更好的商业决策；在浏览器页面就能设置参数来执行假设分析。

He had besides the things before mentioned, twelve marbles, part of a jews-harp, a piece of blue bottle-glass to look through, a spool cannon, a key that wouldn't unlock anything, a fragment of chalk, a glass stopper of a decanter, a tin soldier, a couple of tadpoles, six fire-crackers, a kitten with only one eye, a brass doorknob, a dog-collar -- but no dog -- the handle of a knife, four pieces of orange-peel, and a dilapidated old window sash.

除了以上提到的那些玩意以外，还有十二颗石头子；一只破口琴；一块可以透视的蓝玻璃片；一门线轴做的大炮；一把什么锁也不开的钥匙；一截粉笔；一个大酒瓶塞子；一个锡皮做的小兵；一对蝌蚪；六个鞭炮；一只独眼小猫；一个门上的铜把手；一根拴狗的颈圈――却没有狗――一个刀把；四片桔子皮；还有一个破旧的窗框。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
