Based on the characterization of anomalies and interference frequency in geochemical exploration, a new method to eliminate interference by using wavelet analysis is established, and a theoretical model of anomaly types and their formation mechanisms is developed.

A synthetic CDP gather or AVO forward modeling can be used to make amplitude recovery more reasonable and to identify AVO attribute type for gas reservoir that are useful in AVO interpretation.

Aerocraft is easy to impact with hailstone and may cause serious damages during its flight,so it′s necessary to investigate hail impact on aerocraft by trial system.

The methods of speedup are proposed under the limitation of the strength of hailstone pill.

The hailstone impacting test system is constructed basing on the theory of air gun which energy is offered by compressed air.

Echo characteristics,circulation background and environment variables during a hailstorm in Akesu were analyzed by using basic CINRAD/CC data and its production.

The hailstorm occurred on July 6 to 8,2003 over the northeast of Qinghai-Xizang plateau was simulated by using MM5,and its meso-scale circulation background and local convective cells characteristics were analyzed based on simulated data.
