前兆

Geller et al.122 proposed that the question of precursor test can be addressed using a Bayesian approach where each failed attempt at prediction lowers the a priori probability for the next attempt.

Geller的文献2提议，关于前兆试验的问题可以采用一种Bayesian方法来处理，即，预测方面的每一次努力的失败将降低对进行下一努力的先验的概率。

These were warning signs of a storm.

这是暴风雨的前兆。

However, it was not a good omen that the day after taking office he was forced to admit to a string of adulterous affairs.

然而，就在他就职后的一天，不好的前兆就出现了，他不得不承认和一系列通奸事件有关。

It's a sign of impending arousal.

这是你即将射了的前兆。

Discussion on the Problems about Encrustment in Geothermal Heating System

前者可由人直接观察得到，称为宏观前兆，后者只能用仪器检测，称为微观前兆。

There are no seismometric and precursor monitoring stations within 200km from the epicenter.

本次地震前震中周围200km范围内，无测震台站和其他定点前兆观测台站，沿海地区也未观测到定点前兆观测异常。

There were 25 seismic stations within the distance of 200 km from the epicenter.15 of them were seismometric observation stations and the other 18 of them were precursory observation stations.

在震中200km范围内共有地震台站25个，其中开展测震观测台15个，其他前兆观测台18个，5.8级地震前共出现10项异常，其中地震活动性异常4项，其他前兆观测异常6项。

There were 10 seismometric stations （ including telemetric stations ） and 13 precursor monitoring stations with 17 observation items within the distance of 300 km from the epicenters. There were 18 medium term, short term and imminent anomalies. 7 of them were anomalies in seismic activity and 11 items were precursory anomalies. The proportion of precursory anomalies within the distance of 200 km from the epicenters was 73%.

在1994年度青海省震情研究报告中，根据青海东部存在的地震活动性异常和部分前兆观测异常，将共和地区列为应注意地区2）。2月16日5.8级地震前，根据地震前兆的短临异常，青海省地震局于2月12日填报了短临预报卡片（除共和地区外，同时还圈定了两个地区），并电话通知了共和县塘格木农场，14日向省政府做了汇报，省政府根据震情的发展用电报通知了海南州政府3）。

Proved by long time prevention work and scientific research that coal and gas outburst takes place suddenly but has a lot of auguries including AE before outburst.

长期的防治工作和科学研究表明，煤与瓦斯突出虽然是突发性的，但在突出前均有前兆显现，其中声发射就是前兆之一。

Finally,this paper overviews the difficulties in the observation and research on subsurface fluid and geochemical change taken as some earthquake precursors and proposes the earthquake prediction effort to overcome these difficults,such as adopting a multistage,multisite and multidisciplinary approach;using sensitive telemetered instruments of good long term stability and fine time resolution;developing sufficiently realistic geophysieal and geochemical models;using appropriate statistical methods.

同时指出了对地下流体和地球化学作为地震前兆来观测研究的困难所在以及为了克服这些困难而应该采取的地震前兆观测研究的方向，例如多种手段和多种原理方法，开发有效的地球物理和地球化学模型以及适当的数据分析统计方法等。

On closer examination, though, this is not a vote for multilateralism but just the opposite.

仔细审视后我们发现，这并非是对多边主义投出的赞成票，而是恰好相反。

Uncovering their weak spots, so I can defeat them.

揭露出他们的弱点，这样我就可以打败他们了。
