# 用 Python 实现每秒百万级请求

目前，地震资料解释基本上都采取人机联作解释方法。（地震资料人机联作解释工作的主要内容包括地震构造解释和地震地层学解释。） 软件系统大致可以分为三部分：解释程序、绘图程序和数据管理程序。 三维地震勘探和高分辨率地震勘探。 八、垂直地震剖面（VSP） 从VSP记录提取速度信息仅仅是VSP测量的目的之一。 九、折射波方法 确定近地表层的特征。 十、四维地震勘探 四维地震勘探是重复进行三维观测，第四维是时间。 Over two million people died in the earthquake in the 20th century. About 0.6 billion people live in the strong earthquake zone throughout the world. 讨论： 1地震报道：中日报道不同：历史文化原因 媒体报道目的 2地震预报3难点：研究困难重重。方法局限性。前景或许是死胡同 3日美中三国地震：日本：震得多了，所以体系完善。 美国：有钱+有先进技术，必然要用。 中国：总体措施比较合理，体系尚需完善。 精髓：普及地震教育、发动群众 4GPS和地震：全球定位系统（Global...
