collision bearing
1.According to the relation between Ampere force and Lorentz force,a discussion is in progress from the three aspects including collision mechanism,Hall electric field and force-bearing of lattice ion in the condoctors. The conclusion that the microcosmic mechanism of Ampere force is the composite force system accepted by the cation in lattice is drawn.
3.The zircons of ore-bearing granite at Baizhangzi gold field in Lingyuan, Liaoning Province yield a SHRIMP U-Pb age of (222± 3)Ma, the same with the ages of Dushan granic batholith in the same region and the granite-porphyry in Sanjia gold field. It is suggested that the granites belong to post-collision granites of Indo-Chinese epoch.
