The converter transformer bushing is one of the key devices in high voltage direct current (HVDC) system, which has a complex insulation system. To comprehensively evaluate the insulation properties of ±600 kV dry DC bushing, a finite element model is built and the electric field distributions under complex voltage are calculated. Results show that:(More)
OBJECTIVE To explore correlation of seven apoptosis-related proteins (Hsp90a, p53, MDM2, Bcl-2, Bax, Cytochrome C, and Cleaved caspase3) with clinical outcomes of ALK+ anaplastic large-cell lymphoma (ALCL). METHODS Using immunohistochemistry and immunofluorescence double staining methods, the expressions of these seven apoptosis-associated proteins were(More)
The contents of twenty kinds of trace elements, Al, Ba, Ca, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, P, Pb, S and Zn, were determined by ICP-MS with microwave digestion in Urtica laetevirens Maxim. The recovery (n=7) is 95.4%-101.2%, and the RSD (n=7) is 1.2%-5.3%. The contents of K, P, S, Ca and Na in the samples were abundant while Fe, Mg, Mn and Zn(More)
