追踪

The sequence was composited on an Inferno by Bob Wiatr, who also did much of the tracking himself, using Infernos 2d and 3d trackers.

序列镜头是由鲍勃Wiatr在composited上合成的，他自己也做了追踪的大部分实验，使用composited 完成了2d和3d追踪。

This is figurative, of course; the man feels naked because his private life is so open to government snoops. If he logs onto the internet, his movements are tracked by marketing firms - but this tracking can easily be used for other purposes. If he deletes an e-mail message, he assumes it's gone for good, but it's not: there are "ghosts" in his hard drive. It has long been possible to bug regular telephones, but cellphone conversations can easily be intercepted too.

这个人感到自己一丝不挂，因为他的私人生活对政府的窥探毫无遮拦：如果他上互联网，他的足迹就会被营销公司所追踪--而这种追踪很容易被用于其他目的；如果他删除一封电子邮件，他以为这封邮件永远消失了，但事实并非如此，&鬼魂&还存留在硬盘中；对普通的电话加装窃听装置早就有了，但手机电话也很容易被截听。

Therefore this article introduced the use space surrounding box carries on fast beam tracing on the triangular net model the method, uses this method to be possible fast to complete the up to ten thousand strip beam on the complex model beam tracing, has the very strong practical value.

因此本文介绍了利用空间包围盒在三角网模型上进行快速射线追踪的方法，利用该方法可以在复杂模型上快速完成上万条射线的射线追踪，具有很强的实用价值。

All the pairs of azimuths and dips corresponding to receiver positions can be effectively revised and get the all source-receiver ray trace quickly.

在计算单元自动生成的射线追踪方法基础上，本文结合波前法提出一种快速、有效的两点射线追踪方法。

The characteristics and courage of the Coonhound also make him proficient on the hunt for deer, bear, mountain lion and other big game.

主要是用来追踪浣熊并将它们赶上树去，黑褐猎浣熊犬完全依靠嗅觉来执行任务，他的作为猎浣熊犬特征和勇气使他也能够追踪鹿，熊，美洲狮等大型猎物。

Used principally for trailing and treeing raccoon, the Black and Tan Coonhound runs his game entirely by scent. The characteristics and courage of the Coonhound also make him proficient on the hunt for deer, bear, mountain lion and other big game.

In the thesis, research on network vulnerability analysis and IP traceback is discussed.Under the background of "IP network topology and analysis of performance based on network detection" supported by NSFC, Distributed Network Measurement and Analysis Infrastructure, the cooperant result of our workgroup, is discussed, and also the significance of network vulnerability analysis and IP traceback research in DNMAI; Several existing advanced vulnerability analysis methods and models are compared and summarized. Advantages and disadvantages of each technique are discussed in detail.

论文以国家自然科学基金重点项目(基于网络探测的IP网络拓扑发现和性能分析)工作组提出的分布式网络测量和分析基础架构为背景，在网络脆弱性分析和反向追踪方面做了一些研究工作：说明了脆弱性分析和反向追踪研究在DNMAI架构中的意义和作用；对现有网络脆弱性分析领域的几种先进模型和技术进行分析、比较和综述，详细讨论了各种技术的优缺点。

The pursuit began with the cruisers, which led to the first disastrous action.

开始追踪的是巡洋舰，这次追踪引起了第一次不幸的交锋。

Previous research has shown that smoking cessation enables better health as well lower medical care utilization. However, previous research usually treated smoking as a time invariant variable and hence can not determine the actual economic impact of smoking as time passes. In addition, previous research differs in research design and limited in duration of follow-up after smoking cessation. Hence it is necessary to conduct a study with longer period of follower-up.

虽然有研究证实戒菸可改善健康状况、减少医疗利用，然而上述研究有些系横断性，有些将吸菸状态设计为不随时间改变(time-invariant)的变项，无法呈现随时间改变的吸菸状态对医疗利用的影响；另外过去研究结果依研究设计、追踪年数不同而有所差异，若能追踪较长的时间，更可厘清戒菸时间与医疗利用间的关系。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
