查询词典 foreshock

The research on the quiescent foreshock is of great theoretical and practical significance.

寂静地震的研究具有重要的理论与实际意义。

This means that there is about a 94% chance that any earthquake will NOT be a foreshock.

这意味着一个地震不是前震的概率大约是94%。

In the Pacific Northwest, there is no evidence of foreshock activity for most historic earthquakes.

在太平洋西北地区，历史上的大多数地震都没有前震活动的证据。

Q: What is the probability that an earthquake is a foreshock to a larger earthquake?

问：一场地震是一场更大地震前震的概率有多大？

Even in areas where foreshocks are fairly common, there is no way of distinguishing a foreshock from an independent earthquake.

即使是在前震相当普遍的地区，也无法将前震与独立地震区分开来。

In California, that probability is about 6%. This means that there is about a 94% chance that any earthquake will NOT be a foreshock.

这意味着有大约94%的机会，一次地震不会成为另一场更大地震的前震。

A: "Foreshock" and "aftershock" are relative terms.

答："前震"和"余震"是两个相关的术语。

Also, there was a fairly large foreshock in Chile which caused people to go outside before the main quake hit.

同时，智利此次有一次比较剧烈的前震，因此人们也都在更大规模地震到来之前，转移到了开阔地带。

So, if we can make low probability forecasts, short term (such as those currently based on foreshock and aftershock models) what can society do with them?

所以，如果我们能够做出某些低概率的预测、短期的预测〔如目前建立在前震或余震数学模型基础上的预测〕，社会可以用它们做什么？

The controlling effect of tectonics to evolution of microcracks is analyzed by using the damage mechanics theory. These characteristics can be analogized to kilometer meters as the first effect of earthquake precursors. These studies may be helpful to interpret the foreshock or general foreshock in the moderate or short stage before strong earthquakes.

根据微破裂集结临界条件的相似原理，认为这些特征可以类推到公里尺度，它们有助于解释地震中短期阶段的前震或广义前震分布，作为地震前兆的一次效应。

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。
