地震学的

Research the nature of Earth's Physics and training to acquire seismic, gravity field, the Earth tide, the earth's rotation, and magnetic field, to power, plate tectonics and geophysical exploration geophysics, such as the branch's basic theory, observation instruments, methods of observation and data processing methods, able to independently complete a variety of geophysical observation and data-processing tasks, and with certain scientific research capacity of senior specialists.

主要研究地球的物理学性质，培养能掌握地震学、地球重力场、地球固体潮、地球自转、地磁场、地电、板块构造以及勘探地球物理等地球物理学各分支的基本理论、观测仪器、观测方法和数据处理方法，能够独立完成地球物理的各种观测和数据处理任务，并具有一定科研能力的高级专门人才。

On the basis of the background of the geologic structure and some seismological methods,the seismicity characteristics of the northen section on Yilan-Yitong graben fault were discussed.

依据地质构造背景和某些地震学方法，讨论了依兰-伊通地堑断裂北段的地震活动特征，认为该区域的地震活跃期通常在东北地震区活跃期的"尾声"或平静期开始，具有"首尾相接"的特点。

Typical methods of the first class consist of predictive deconvolution, normal moveout interconversion stacking, f-k transformation, tau-p transformation, parabola Radon transformation and beamforming. They can be called as seismography method based on the geometry. The second class methods, mainly bases on elasticity undulatory theory, through simulation or reversal development method forecast multiple, and then match it with the original data.

比较典型的方法有预测反褶积、正常时差变换叠加、f-k变换、τ-p变换、抛物线 Radon 变换和聚束滤波等，它们可以简称为基于几何地震学方法或"几何滤波类方法"；第二类主要是基于弹性波动理论的方法，通过模拟或反演方法来预测原始数据中多次波，继而从原始数据中匹配减去所预测的多次波。

The accurate measurement of seismometer transfer function is important to interpret and use of seismographic observation data.

数字地震观测系统中地震计传递函数的测定对于观测数据在地震学中的解释和应用是非常重要的。

We also discuss the cutting relationship of slickenside striations of two different plunges and their geological and seismological implications,by pointing out that the curved striations may indicate the low initial shear stress at some localities on the Yinxiu-Beichuan fault before the Wenchuan earthquake.

最后，讨论了八角庙有切割关系的两组断层擦痕的地震学和地质学意义，指出可能指示了映秀-北川断裂面上局部区段震前的初始应力水平较低。

In this seminar course, the instructors will examine our current understanding of the CMB region from integrated seismological, mineral physics and geodynamical perspectives. Instructors will also introduce state-of-the-art methodologies that are employed to characterize the CMB region and relevant papers will be discussed in class.

在这门研讨课程中，各指导者将会从整合地震学、矿物物理以及地球动力学等面向，检视我们现今对核函边界区域的认识，同时在课堂中，指导者也会介绍各种应用于认识核函边界特性的最新方法，并讨论相关的文献。

Study of seismic standard shows that one 〓 magnitude earthquake may cause some extent surface rupture, but the characters of earthquake have proved this fact, if earthquake centre distribute along a fault, or congregate, we cannot rule out to occur a possibility of macroseism (M≥4) in the future.

地震学标志的研究认为，历史地震资料表明，在我国一个〓级地震即可产生某种程度的地表破裂，但是，如果震中沿着断层线分布或集中，那就不能排除今后发生大震（M≥4级）并产生地面破裂的可能性。

The characteristics of the movement and deformation of the crust were traditionally determined with the geological and seismographic methods. However, the result obtained with the geological and seismographic methods is virtually an average one on the time scale of millions and/or hundreds of years, and the current movement and deformation of the crust cannot be described well.

传统上，一般用地质和地震学方法来确定地壳的运动和变形特征，但二者确定的地壳形变结果分别是百千万年和百年左右的平均结果，难以描述现今地壳运动和变形的特征。

Meanwhile,the rate of accumulation of broadband digital seismologic observation data is increasing exponentially,meaning that the research on high resolution seismic imaging of earthquake source rupture process and internal structure of the earth will be an important development trend of seismology in the 21st century.

与此同时，宽频带数字地震观测资料的积累速率按指数增长，这意味着震源破裂过程及地球内部结构的高分辨率地震成像研究将成为21世纪地震学发展的重要趋势。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
