查询词典 on the threshold

In this paper,two nonlinear anisotropic diffusion filtering methods are presented and they are based on the multispectral anisotropic diffusion models proposed by Pope and Acton.We build a couple of new diffusion coefficients in partial derivative equation based on Tukey's biweight estimator error norm by recurring to the relationship between robust statistics and anisotropic diffusion incorporated with the nonlinear time-dependent cooling technique for gradient threshold.

巫婆医IV偏重于解开玛雅之谜；玛雅挂历停泊在2012年12月21号的预言，人类将跨越而步入一个新的时代，并颠末多年的动乱后，将使某种很是深刻的变化。

Medicine Woman IV focuses on the ultimate Mayan mystery; the MAYAN CALANDER which stops on the 21st December 2012 with the prophecy that humanity will cross the threshold into a new era and will make some kind of very profound change after years of turmoil.

2009年推出的《Medicine Woman IV》（女巫医4：2012年预言）着重于玛雅之谜——玛雅日历上记载的预言说，2012年12月21日将是玛雅人所预言的&世界末日&。当玛雅第五太阳纪结束时，必定会发生太阳消失，地球开始摇晃的大巨变。

The ordinary edge detection methods such as Sobel and Canny operators are immune to noise, which result in cophasal axes discontinuity due to lack of edge information caused by noise. In order to extract cophasal axes more continuous and immune to noise, a novel approach is developed based on edge detection. Firstly, the median filter and improved Sobel method are used to preprocess seismic section images. Secondly, the threshold value is determined automatically based on variance to detect abnormal information. Finally, the complete cophasal axes are extracted after a post-processing.

由于边缘检测中常用的Sobel算子和Canny算子检测同相轴时对噪声免疫差，常因噪声因素引起边缘信息缺失导致同相轴提取不连续，本文采用中值滤波并对Sobel算子进行改进，对地震剖面图进行预处理，结合均方差自动确定阈值并进行异常检测，提取完整同相轴。

The results showed that the cadmium pollution increases the contents of total protein and globulin,and decreases the ratio of albumin to globulin.The effect of cadmium on albumin is not statistically significant.The threshold of effect of cadmium on sero proteins of Tilapia mossambica is 0 005mg/L.

试验结果表明，镉能升高血清总蛋白、球蛋白含量，降低白蛋白／球蛋白比值，但对血清白蛋白含量没有影响；镉对血清球蛋白各组分的影响有其特异性；对莫桑比克罗非鱼血清球蛋白成分产生作用的镉浓度阈值为0.005mg／L。

Among the policies we have written and retained entirely for our own account are (1)$578 million of property coverage for a South American refinery once a loss there exceeds $1 billion;(2)$1 billion of non-cancelable third-party liability coverage for losses arising from acts of terrorism at several large international airlines;(3)￡500 million of property coverage on a large North Sea oil platform, covering losses from terrorism and sabotage, above ￡600 million that the insured retained or reinsured elsewhere; and (4) significant coverage on the Sears Tower, including losses caused by terrorism, above a $500 million threshold.

自从 911 事件发生之后，Ajit 就变得异常忙碌，在我们承接且全部自留在公司帐上的保单，主要有(1)南美洲炼油厂损失超过 10 亿美元以上的 5.78 亿美元意外险(2)数家国际航空公司 10 亿美元恐怖份子攻击事件不得撤销第三责任险(3)北海原油平台 5 亿英镑恐怖份子攻击及恶意破坏的产物意外险，以及超过 6 亿英镑以上业者自留或再保损失(4)芝加哥 Sears 大楼恐怖份子攻击事件超过 5 亿美元以上的损失等；此外我们也接了许多项超大型的意外险，例如世界杯足球赛以及 2002 年冬季奥运等，但不论是那一件个案，我们都尽量避免会发生连锁反应大量累积损失的保单，比如说，我们不会一口气接下位于同一个大都会的办公及住宅大楼大量的意外险，除非排除核子爆炸及后续可能引发的火灾损失。
