With XRD and IR, the authors conducted studies on the intercalation of acrylamide andsalts of fatty acids in kaolinite of coal-bearing strata and its stability.

In the example of HgS/CdS spherical nanometric system,the effect of system size and the layers mutual effect has been discussed in terms of the electronic potential energy.

Under the layers mutual effect, a physical model and an equation applied to electronic potential are worked out of the multi-layer spherical namometric system.

In consideration of the disturbances of the Datong Basin reach of the Sanggan River during late Qua-ternary time caused by external variables,such as the emplacement of basalts,along-valley faulting pro-cesses and climate changes,a conceptual model is developed for distinguishing fluvial incision induced by faulting from that induced by climate.

This paper deals with the latest Pleistocene faulting on the Canfangying segment of the faultzone along the northern margin of the Yanqing basin from the data of one trench, three geologicprofiles, seven fault scarp morphologic profiles across the late Pleistocene deposit surface and fif-teen radiometric datings.

The underplating, convecting, and delamination are the three major mechanisms in the continental rifting and extensional geodynamic system.
