As others have concluded, the foreshock sequence (Fig. 7) was the most important evidence used in the imminent prediction of the Haicheng earthquake.

"It was the foreshock sequence that gave the solid prediction," Michael said.

从文章中看，借助动物预测地震是否可靠在学术界也没有统一的看法，中国、日本还在做，美国已经停止了官方的研究，停止的原因不是钱，而是"教条主义和小心眼"。

Through statistical analysis, it is demonstrated that the precursory wave related to the quiescent foreshock is more universal than the foreshocks.

统计表明，与寂静地震有关的前驱波比前震有更大的普遍性，出现的时间主要集中在主震前 7天之内，从一部分中等地震到特大地震之前都已观测到前驱波，这就说明大的脆性破裂之前，较小的缓慢破裂在自然界是存在的而且比较普遍。

A single pure quartz crystal does not show any foreshock as a force is applied to it, it simply breaks when it can no longer withstand the pressure.

一块纯石英晶体在受到压力时，不会表现出任何预震，它只会在不能继续承受压力时破裂。

The data from two same satellites (CLUSTER C1 and C3) were used to make a statistical study of the solar wind deceleration and deflection in the Earth′s foreshock region for the first time.

本文首次利用完全相同两颗卫星（CLUSTER C1和C3）的数据对地球激波前兆区太阳风的减速和偏转特性进行了统计研究。

This is the basis for the 'automatic alarm' prediction strategy494: issue an alarm automatically after every earthquake above a certain size, on the chance that it might be a foreshock of a larger earthquake.

这就是'自动报警'预测战略的基础94：在每次超过一定规模的地震后自动报警，以便碰运气它可能是更大的地震的一次前震。

到上午08：00，总共记录了200多次小震，07：51时最后发生的前震最大达到ML5.1〔Ms4.7〕。

The types of sequences and features of foreshock and aftershock activities of 18 MS≥5.0 earthquakes since 1970 along Qilian—Haiyuan seismic zone are studied.The space distribution of types of the sequences along the zone is analyzed.

研究了1970年以来发生于祁连—海原地震带的18次中强地震序列特征，在此基础上确定了地震序列类型，研究了各种类型地震序列的分布规律。

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。
