追踪

The prospect of allowing untraceable commerce to bloom on a federally subsidized network would probably have the U.S.

在由联邦资助的网络中允许不可追踪的贸易繁荣发展，这样一种前景，如果政府真动脑子去想一想的话，是会非常忧虑的。

On the hill, the lead guide sets the track and the guests follow, with everyone skiing in fresh, untracked snow.

在山上，带头指导组的跟踪和后续的客人，大家滑雪新鲜，未追踪的雪。

With unwearied diligence, his eyes pursued the object till it gradually disappeared.

他的眼光毫无松懈地追踪著这个物体，直到它逐渐消失。

"The tell-tale tracks in the airflow caused by the wing beat have a very different pattern for bats, and this difference can be traced to the peculiar upstroke," he continued.

"告诉的故事，追踪在气流所造成的永安队有一个非常不同的模式，蝙蝠，这种差异可以追溯到特殊upstroke ，"他续说。

Mean operating time was 40 minutes (range, 30-90 minutes), and mean hospital stay was eight hours (range, 6-48 hours). One patient developed a small, local extravasation of fluid, but there were no other perioperative complications. At six weeks after the procedure, patients had catheter removal and voiding cystourethrography, followed by urethroscopy one month later.

平均手术时间是40分钟(范围在30-90 分钟)，且平均住院时间为8个小时(范围在6-48小时)，其中一位患者发展较轻微，只有部分的液体外渗，除此之外没有其它手术后并发症；手术后6个星期，患者移除导管并做排尿膀胱摄影，一个月后以尿道镜检视法追踪。

At a mean follow-up of 15 months (range, 10-19 months), 19 (65.51%) of 29 patients had excellent results, and nine patients (31.03%) had acceptable results. HolCTU failed to maintain good flow in the latter group, necessitating internal urethrotomy/endoscopic dilation once or twice for stabilization (maximal flow rate 15 mL/s or greater). One patient (3.44%) had recurrent obstruction despite repeated internal urethrotomy, which finally required formal transpubic urethroplasty. All of the patients were continent, with no change in potency status.

经过15个月的后续追踪(范围在1 0-19个月)，29位患者中有19 位(65.51%)患者有极佳的效果，另有9位(31.03%)患者有可以接受的效果；不过，后面几组无法以尿道造口术维持好的流动，为了稳定流速，需要一至两次内部的尿道造口术/内视镜扩张术(最大流速为5 mL/s 或更大)；有1位(3.44%)患者虽然重复接受内部尿道造口术，但是一再发生阻塞，患者最后需要经正规的耻骨尿道成形术，全部患者可在不影响性功能的情况下控制排尿。

This paper has done some studies on arithmetic for this system: presents a method of detecting and tracing moving objects in real time, and analyses their height using the restriction of vanishing line s, vanishing points and cross-ratio in perspective geometry.

文中为实现这种智能视觉监控系统做了一些算法上的研究工作：实现了对运动物体进行实时检测和追踪，并利用透视几何中的消影点、消影线以及交比的约束方法对运动物体高度进行了分析。

Variable material and labor costs that can be directly traced and allocated to a specific unit of production.

可直接追踪及分摊到具体生产部门的变动物料及人工成本。

In this paper, a lot of research works of algorithms of mining CAD has been done. Many important mine specialty graph operation algorithms have been put forward. The main results are as follows: polygons cut out algorithm, two close polygons mutual, merge and subtract algorithm, polygon vector fill, any vector polygons area calculating and sequence polygons or multifold which has the direction and region area calculating, curve smoothing, graph element search for any region, graph element attrib collect in any region, parallel polygon or vector intersection-point push out or pull in, ore reserves and grade calculating for any type polygon, mine spatial data searching and boundary line tracking and automatic link algorithm etc.

From a uncertain point which located outside of the figure to draw radial, according to the junction of radial and polygon to judge the internal and outside relationship; Boundary algebra filling, a vector convert to raster arithmetic which based on integral thought, suit for polygon vector convert which

录拓扑关系的多边形矢量数据转换，方法是由多边形边界上某点开始，顺时针搜索边界线，上行时边界左侧具有相同行坐标的栅格减去某值，下行时边界左侧所有栅格点加上该值，边界搜索完毕之后即完成多边形的转换。关系，并表示成矢量格式边界线的过程。步骤包括：多边形边界提取，即使用高通滤波将栅格图像二值化；边界线追踪，即对每个弧段由一个节点向另一个节点搜索；拓扑关系生成和去处多余点及曲线圆滑。
