地震学的

With the fast development of digital seismology, doublet earthquake is taking an important role in studying of seismology.

随着数字地震学的快速发展，重复地震在地震学的研究中显得越来越重要。

The bright star Procyon has been considered one of the best candidates for asteroseismology, on the basis of models and previous reports of p-modes detected in ground-based spectroscopy.

这样的压力波是天体地震学的基础，该学科是研究太阳内部结构的一个强大工具，所以天文学家认为同样方法也应适用于 Procyon。

Development of seismology is marked first by seismologic observation techniques, the reification of which is the evolution of seismometers.

地震学的发展首先表现为观测技术的发展，而地震计的发展是观测技术发展的最基本环节。

This new method may greatly advance the development of seismology.

该方法将会大大促进地震学的发展。

The study of seismology enables us to know more about earthquakes.

地震学的研究让我们认识地震。

Great progress has been made in some "hot spot" areas of the geoscientific research, such as the Tibetan plateau, the western Pacific subduction zone, the North China Craton and the South-north seismic belt.

笔者对青藏高原、西太平洋俯冲带、华北克拉通和南北地震带等地区多年来一直存在争议的几个重要地学问题进行了简要的总结，并从地震学的角度出发，对问题的解决提出了粗浅的见解与看法。

In this project, we have deduced the joint inversion model of geodetic data, seismic data and geological data considering about their weight ratio; presented Bayes-iterative search inversion algorithm which improved on the traditional Bayes algorithm and strengthen the stability of inversion solutions; enriched and developed geodetic joint inversion theory and method of tectonic stress field; joint with geodetic, seismic, geological and geophysical data, we have inverted the temporal and spatial variation characteristics of crustal deformation of active tectonic blocks in North China and the present-day cruatal movement and strain-stress field by FEM, DDA and bi-cubic spline function fit method; especial for the crustal deformation result in some typical areas, we have presented geodynamical interpretation and done some seismic dangerous estimations.

大地测量联合反演构造应力场属于大地测量与地球动力学和地震学的交叉研究领域，主要内容是研究用大地测量地壳运动监测数据定量研究地壳运动和变形的动力学问题及分析预测地震，本项目推导了兼顾权比确定的大地测量、地震和地质三类数据的联合反演模型；提出贝叶斯-轮回搜索反演算法，改进传统的贝叶斯方法，改善反演解的稳定性；丰富、发展了大地测量反演构造应力场理论及方法；联合大地测量、地震、地质、地球物理数据采用有限单元法、块体不连续变形分析法和双三次样条函数拟合方法反演分析了华北地区活动地块运动时空变化特征以及中国大陆现今地壳运动与应变-应力场，对典型地区地表形变结果进行地球动力学解释并进行地震危险性估计。

First, we introduce the linearly distributed stress tensors as the source and by means of two-dimensional finite-difference scheme to obtain the response of this source, then the point source response is generated by correcting both the wave forms and geometrical spreadings for the linear respons.

但在理论地震学，工程地震学和勘探地震学中横向不均匀介质中的波传播问题非常重要，此时使用有限差分法和有限元法等离散数值方法比较有效。鉴于目前计算工具的限制，三维模型的有限差分计算虽然在理论上是可行的，但很少能用于实际。

The collective conscious and unconscious processes in a sentient organism that direct and influence mental and physical behavior.

在这里我们只讨论和理论地震学及实用地震学都有直接关系的波动传播问题的两个特例。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
