It is a great concern in international oceanology to mine cobalt-rich crust. At present, spiral mining head is regarded as the best crushing scheme. Based on the dynamic model of spiral mining head, the of cobalt crust’s crushing process was simulated with the ANSYS software. The material model of Johnson and Cook Plasticity, maximal princi- pal stress failure criterion, and eroding contact arithmetic were selected. At the same time, the influence of cutting depth, feed speed, rotational speed of mining head on torque and force subjected by mining head was taken into account. At last a computer simulation model of crushing process of cobalt crust was established. By analyzing simulation results, the relationships among these controllable process parameters, torque and force can be obtained, which will provide a technical reference for practical mining system.

OBJECTIVE To explore the effects of cisplatin chemotherapy via the vein and the abdominal cavity on the functions of endothelial cells of mice with non-small cell lung cancer. METHODS 75 mice were divided equally into a untreated group, a group treated with chemotherapy （cisplatin： 2 mg/kg, 0.5 mL） via an intravenous method and a group treated with chemotherapy （cisplatin： 2 mg/kg, 0.5 mL） via an intraperitoneal method; changes in the morpholoqy and ultrastructure of vein endothelial cells were observed.

The catalytic dehydrogenation of methanol over supported Cu/SiO2and Cu/Al2O3prepared by impregnation and by ion-exchange (Cu/SiO2（im）,Cu/Al23（im） and Cu/SiO2（ex）), La2O3and ZrO2promoted Cu/SiO2or Cu/Al2O3catalyst has been studied in a fixed bed microreactor at 250℃ and atmo-spheric pressure. The Cu/SiO2（ex） catalyst was found to be very active and se-lective toward methyl formate （MF）. However, Cu/SiO2（im） catalyst wasless active and selective among the studied catalysts. The catalytic activity, MFselectivity and MF yield over Cu/SiO2And Cu/Al2O3are greatly improved byLa and Zr. XPS and XRD results suggest that the crystallite size of copper wasreduced by coating La and Zr, the surface Cu/Si or Cu/Al atomic ratio in-creased. TPR results show when the support was coated with La and Zr thepeak temperatures of catalysts significantly decreased.
