Based on lots of experiences from the oil sand exploration,the oil-sand forming model of the slope spill-scattered type are proposed in this paper.

Distribution of incidence wave pressure inward normal to broken stone slope;

Based on an ideal slope-profile model as well as spatial convolution transform with target extension,a MTF approach was proposed to solve on-orbit evaluation for thermal infrared band of sampled imaging system.

Based on the principle of pseudo static loading and centrifugal model testst,he dynamical characteristics of landslips of loose slope under seismic loading are analyzed by means of the landslips of sand-pile models with one slope,which are used as simplification pattern of loose slopes.
