本软件基于MAPX5.0控件的开发这个系统本来应该注重于查询的,但查询有点问题,精确查询还好,模糊查询是错误的,大家可以看我的代码,模糊查询应该和精确查询是一样的,只是查的是所有图层罢了.所以我想请教一下大家怎样可以模糊查询,看了代码,照着做了,好像还不是很行,^_^.现在想把它完善一下,改的地方有鹰眼和查询结果做为浮动窗口,地图自动适应窗体的改变,其他还没想好.-MAPX5.0 based on the software controls the development of the system should focus on the inquiry, but for some problems, precision inquiries Fortunately, fuzzy inquiry is wrong, we can look at my code, fuzzy inquiry and precise inquiry should be the same, just check all the layers is just . Therefore, I would like to ask you about how fuzzy inquiry, read code suffices to follow them, do not seem to be OK ,^_^. want it perfect now that the place has changed and the Eagle Eye as a result of inquiries floating window, the map automatically adapt to changes in the form, not to other good . Oh

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
