2.The Landsat5 TM imagery in 1998 is used as the original data to calculate the planet albedo after calibration correction and radiation correction. Based on the simple theoretical model of atmospheric correction,according to the reflectivity of vegetation in the shadow in a mountainous area,the transmittance in up direction is calculated. In reverse,the atmospheric optical thickness and the transmittance in down direction along the incidence direction are reached and the parameters of atmospheric correction are identified.
3.The pre-seismic and post-seismic stress direction can be statistically determined by a large collection of foreshock and aftershock focal mechanism data while the stress drop can be determined through the source fracture inversion from seismic wave data or crust deformation data.
4.By the Bitter pattern technique and the energy analysis method, we systematically studied the character and variations of domain structures during the magnetization reversal process along the hard-axis direction of a 40 nm NiFe film stripe. It shows that the Barkhausen jumps in the element are the result of the irreversible domain processes, involving domain wall mergence, closure domain transitions, and wall-state transitions.
