应用背景随着地震勘探精度的提高,各向异性对于常规克希霍夫叠前深度偏移效果的影响已不容忽视.研究了利用P波非双曲旅行时求取各向异性参数的方法,当道集的排列长度远大于勘探目的层深度时,P波走时资料包含的信息可以用来确定VTI介质的各向异性参数关键技术利用VTI介质的CMP道集,研究了二步法提取η参数的方法,即先利用短排列地震数据求取均方根动校正速度,再利用长排列数据和水平速度扫描法得到水平速度,通过转换得到各向异性η参数；采用基于声学近似的VTI介质程函方程,通过各向异性射线追踪计算旅行时

目前支持autocad中DWG文件读写的源码除了用python写的phythonCAD，恐怕就只剩这个了。可是为什么该站要限定java和C才开通呢，其实有一些其他语言的源码也很经典啊-Currently supports autocad in the source code to read and write DWG files besides using python write phythonCAD, I am afraid the only place this has been. But why the station should be limited to java and C only to open it, in fact, have a number of other languages source code is also very classic ah
