地震震级

It is turns out that the average seismic apparent stress calculated with seismic magnitude in Chinese mainland is similar to that calculated with digital seismic wave data and the distribution is coincident with each other.

研究表明：利用地震震级计算的中国大陆地震视应力大小与利用数字地震波资料测定结果相差不大，其空间分布基本一致。

Furthermore the formulae for calculation of the magnitude as well as the method for calculation of the elastic coefficient of the rock around the bore hole are derived.

文中还导出了计算地震震级的公式和计算钻孔周围岩石弹性系数的方法，不但解决了上述难题，还使计算大为简化。

Earthquakes are measured on the Richter scale – this is a logarithmic scale – what does the mean?

地震震级以里克特计算——这是一种对数的等级—这是什么意思呢？

This paper focuses on the conditions of formation of the tsunami and factors controlling the magnitude of earthquake.

此外，本文还探讨了破坏性海啸的形成条件和控制地震震级的主要因素。

The delay time of vertical coseismic deformation have positive linear relationship with ep...

断层体垂直向同震形变延迟时间与震中距线性正相关，发生地震同震形变的响应速度约为5.5km/s，反映了在上层花岗岩地层中面波的传播速度；同震位移最大振幅和震中距的对数、震级之间具有明显线性关系，震级越大，同震位移的最大振幅越大；地震震级是断层体垂直同震形变振动持续时间的主要影响因素，震级越大，同震形变振动持续时间越长。

Taking Yuminli Ward, Beijing City, as an example, the determination method and calculation process of scenario earthquake are systematically illustrated in the thesis.

论文以北京市裕民里小区作为场点，系统地阐述了设定地震震级和震中距的确定过程和计算方法。

More extensive logistic tree cited to describe an earthquake in graph of seismic division into districts tectonic geometry configuration, magnitude and the uncertainty with periodic recrudesce, among them diagnostic earthquake model includes: Sign of ザ grain screen is cast? of P of Wu of an ancient small-mouthed wine vessel of Jian of an ancient small-mouthed wine vessel of breasts of grain screen model and the float earthquake model that give magnitude of model of not fixed section.

在2008年地震区划图中引用了更为广泛的逻辑树来描述地震构造几何形态、地震震级和复发周期的不确定性，其中特征地震模型包括：单段破裂和多段破裂的特征地震模型，以及给定震级的浮动地震模型。

It studies the variations of deformation modulus, P wave velocity and acoustic emission in the process of rock fracture by cycle loading. Further, it is considered that the occurrence of earthquake outside Lijiang seismic area made the forced process changed, therefore, the Lijiang M7 earthquake came later, the impending precursory anomalies became unclear or complicated, and the magnitude decreased.

用循环加载研究岩石破裂孕育过程中变形模量、纵波速度和声发射的变化特征，进而探讨认为丽江地区外部地震的发生使受力过程发生了变化，从而使丽江7 级地震延迟发生，也使临近地震的前兆异常不明显或更复杂，并使丽江地震震级减小。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
