查询词典 inversion principle

The inversion of particle size distribution from measured data of light scattering, as a typical inverse problem, has been studied by many reseachers and solved by several numerical methods. Among which, direct Tikhonov regularization method with Morozov discrepancy principle, is often used to overcome the ill-posedness linked with the Fredholm integral equation of the first kind, so the stability of inversion has been heightened. But there has much room for improvement of the inversion accuaracy, especially for the double-peak problems.

由测量得到的散射光强数据来反演颗粒粒径分布是一个典型的反问题，它已为许多的学者所研究，并用多种数值方法来求解，其中带Morozov偏差原理的直接Tikhonov正则化方法经常被采用，以便用来克服与上述反演相联系的第一类Fredholm积分方程的不适定性带来的困难，因而反演的精度得到了提高；然而仍有许多改进的余地，特别是对于所谓"双峰"问题更是如此。

For a start, before the seismic inversion it is essential for a reservoir to enhance the basic research of the rock geophysical characteristic analysis, horizon calibration, fidelity processing and model analysis, etc., and of the reservoir's lithologic character, physical, electrical and gas bearing property. Subsequently based on the fundamental principle of seismic inversion, a series of inversion methods and their application conditions were emphasized. Finally, taking Labureng area as a target, by comparing various inversion effects, we aimed at enhancing the precision of seismic image, increasing SN ratio and resolution, and highlighting seismic responses of the target strata, and presented reliable geophysical references for the understanding of reservoir evaluation, gas bearing modelbuilding and reservoir mechanism in HJQ area.
