According to theprinciple of annexation, calculating models of mass action concentrations for severalbinary metallic melts have been formulated. The calculated results agree well withpractice, showing that this principle is a reliable basis for determination of the struc-tural units for some binary metallic melts.展开更多

Planning schemes of New Pingdi and Xiangyunzhuang Village were analyzed from six perspectives: selection of new village site, planning structure, planned road, architectural layout, public facilities and landscape design. It was then proposed that "village relocation and annexation" could not only save investment in public infrastructure, but also improve land use efficiency, thus it was an important approach of optimizing distribution of land resources.展开更多

Rabbits and rats were given Annexin32 by intravenous administration. Then Kaolin partial thromboplastin time (KPTT), thrombosis in vitro and in vivo were assayed. The results showed that KPTT of rabbits was prolonged (p < 0.01), and the length and weight of thrombus in vitro were reduced (p < 0.01) after administration of Annexin32 at 1 mg/kg. It also inhibited thrombosis in vivo and reduced the weight of venous thrombus significantly in rats (p < 0.01). All these results suggested that Annexin32 possesses the characteristic of antithrombotic effect and fewer side effects on coagulation time.展开更多
