Generalized screen propagators (GSP) can be considered to be super-wide-angle one-way propagators with implementation in dual domains,which neglect reverberations between heterogeneities but correctly handle the forward multiple-scattering,including focusing/defocusing,diffraction,refraction and interference of waves.

Application of wide angle reflection in seismic acquisition in complex mountainous area.;

NMO method of wide angle reflection with truncation error correction;

And the techniques such as wide angle reflection information extraction, interacted dynamic NMO correction muting in CMP super-gather, are first brought forward in Jianghan.

The spraying cooling designs, made up with wide spraying nozzles, was used in this new kind of cooling tower and got a better effect.

Recently, more and more people focus on the wide angle reflection(WAR), which is a very important way of obtaining high quality seismic data by exploring in fields.

A seismic survey method called wide angle reflection(WAR) used for exploration of weak reflectors below shielded layer of high velocity was described in this paper.
