The results of numerical simulation and experimental investigation of a prototype of a megawatt multifrequency gyrotron for controlled thermonuclear fusion facilities are presented. In experiments, the gyrotron has operated at six frequencies in the range 105–152 GHz with small diffraction losses in the internal quasi-optical system and a high Gaussian mode content in the output beam. 相似文献

Acetylcholinesterase (AChE) and neuropathy target esterase (neurotoxic esterase, NTE) are two major target enzymes for organophosphorus (OP) esters. The relative potency of an OP ester to react with AChE or with NTE in vitro correlates with its relative potency in vivo to cause acute toxicity (death) or organopohosphate-induced delayed neurotoxicity (OPIDN). On this basis extrapolation from in vitro to in vivo data now seems justifiable to predict risk of OPIDN. The kinetics of NTE and AChE inhibition by experimental pesticides of the general formula (RO)2P(O)ON=CClCH2Cl, where R = methyl, ethyl, isopropyl, propyl, isobutyl, butyl, pentyl, has been studied. Compounds with short R (methyl, ethyl) were shown to be far more potent inhibitors of AChE than NTE. Both anti-NTE activity, selectivity for NTE and, correspondingly, the propensity of compounds to cause OPIDN rise with increasing their hydrophobicity. A high value of ki(NTE)/ki(AChE) for R = pentyl suggests that this compound would have the potential to cause OPIDN at doses lower than the LD50. A quantitative structure-activity relationships (QSAR) analysis indicated that NTE and AChE have different structural and electronic requirements for their respective OP inhibitors. 相似文献

This work examines polymorphic transformations in a silica matrix-titania coating system produced by molecular layering. The presence of surface rutile formed during the synthesis of the coating enables a reduction in the temperature of full anatase-to-rutile conversion by }~ 100°C in comparison with an anatase layer. Both the matrix and the oxide layer influence the polymorphic transformations in the SiO2-TiO2 system. 相似文献

The directional solidification of binary systems is theoretically studied in the presence of an extended phase-transition zone. A mathematical model is developed for this process, and its approximate analytical solution is constructed with allowance for a nonlinear liquidus line equation. 相似文献

The way in which silica and titania modification additions are introduced into alumina is shown to have a strong effect on
the microstructure of sintered Al2O3-SiO2-TiO2 materials. By combining molecular layering and mechanical mixing, materials with a controlled pore structure can be obtained. 相似文献
