The bos image is restored and the device database is merged (similar to a conventional migration).
恢复bos映像并合并设备数据库(类似于传统迁移)。
This is much simpler and faster than restoring a mksysb image (via NIM, tape, or DVD), as you would with a conventional migration method.
这种方法比(通过NIM、磁带或DVD)恢复一个mksysb映像更简单快捷，只有在使用传统迁移方法时才需要那样做。
At the same time, the complex characteristics of underground structure make conventional stack and post-stack migration methods can not accurately imaging.
同时，由于地下复杂构造特征使得常规叠加和叠后偏移方法不能准确的成像。
With the requirment of precise seismic interpretation and thoroughgoing exploration, the conventional post-stack migration reveals its limitations.
随着勘探和开发对地震资料处理成果的要求越来越高，常规叠后时间偏移处理技术的缺陷日益显现出来。
In complicated fault areas, however, the effect of conventional time migration processing was poor, which was mainly caused by the big saltation of transverse velocities.
而在复杂断裂区。常规时间偏移处理效果往往不好，这主要是由横向速度突变引起。
The reason of Doppler migration and the restraint of conventional Doppler filter were analyzed firstly.
分析了多普勒走动出现的原因，以及常规多普勒滤波器的限制。
Then two conventional envelope migration compensation algorithm was introduced, on this basis, a new algorithm called frequency domain correction was proposed.
接着介绍了两种常规的包络走动补偿算法，在此基础上提出了一种新的算法称之为基于频域校正的包络补偿算法。
The conventional velocity analysis does not consider the influence of the NMO velocity varying with offset, making the results not ideal, leading to a poor stacking and migration imaging.
由于动校正速度是随偏移距变化而变化的，而常规速度分析并没有考虑这一因素，动校正效果往往不是很理想，从而影响资料的叠加和成像效果。
