Assumed the soil structure being well distributed,the depth set in the soil of the supporting structure of double layer supporting point can be determined through analyzing and calculating different horizontal component forecs of the double layer supporting points on the conditions of being functioned by the ground additional load,and of the contrary.

Double structure clouds with points and local least-squares curve fits are applied to obtain the second spatial derivatives, which is different from the traditional gridless method.

The negatively charged exciton in double-layer quantum dots;

After modeling satellite networks with two-level-node graph, a fault identification algorithm based on PMC test invalidation model is presented and proved to be correct.

A novel modeling method for satellite networks,two-level-node graph,was presented to characterize the specialty that a satellite could have more than one communication directions and its communication function could be faulty partly.
