It is shown experimentally that the base drag of bodies of revolution in Mach 1.15 to 3.0 flow can be completely eliminated using special techniques for injecting hydrogen and the products of incomplete combustion of pyrotechnic compounds into the near wake. The experimental data obtained are generalized. 相似文献

In the hydrogen bubble chamber study of the4Hep→dppn reaction at incident alpha 8.6 GeV/c momentum the structures in the two-proton effective mass distribution are observed at 2,035±15 MeV and 2,137±15 MeV. Possible nature of the effect is discussed. 相似文献

The influence of modification of semi conductive ZnO and SnO2 sensors by porphyrins and their metal complexes on the parameters of sensor response to volatile organic compounds, ethanol,
acetone and benzene, was analyzed. The concentration of volatile organic compounds (c

and R
0 are measurable and initial resistance of the sensitive sensor layer correspondingly. It was established that the modification
of sensors by porphyrins caused changes in sensor response and first of all decrease of ZnO sensor temperature at which the
threshold of sensitivity is achieved (as used at this method c
i
min = 0.1 ppm) from 300 to 100°C. It also caused a change in sing of the parameter γ, which was of importance for creating “electronic
nose” sensor systems. It was shown also, that the modification of ZnO sensor by metal complexes of porphyrin did not change
sensor response parameters. 相似文献

It was shown that carrying out the reaction of cholesterol photosensitized oxidation in the presence of porphyrins immobilized
on the hydrolyzed copolymer of tetrafluorethylene and H+ form of perfluoro-3,6-dioxo-5-methyl-6-sulfonylfluorideoctene-1 leads to the formation of not previously described new products:
6β-phormyl-B-norcholestan-3β,5β-diol, 6β-chlorocholestan-3β,5α-diol, cholestan-3β,5α,6β-triol, and 5α-chlorocholestan-3β,6β-diol. 相似文献

Effect of ethylene and propylene oxide tri-block copolymers (Pluronics) on the photocatalytic activity of tree porphyrins differing by their hydrophobicity was studied. It was shown that Pluronics induce considerable increase in the photocatalytic activity of the tetraphenylporphyrin, hematoporphyrin disodium salt (Dimegine) and relatively hydrophilic N-methyl-bis-glucamine salt of chlorine e6 (Photoditazine) in the reaction of photooxidation of tryptophan in water solution. This effect was maximal for Pluronics F127 and P85 with intermediate hydrophobicity, while more hydrophilic F68 and more hydrophobic L61 were less effective. Pluronic effect on the photocatalytic activity of tetraphenylporphyrin and dimegine is attributed to their disaggregation in water solution, while PD activity is elevated due to the local concentrating of the photocatalyst and the substrate within micellar volume. It was found by AFM that the structure of Pluronic F127 thin films prepared by water solution evaporation on mica surface significantly changed in the presence of porphyrin. This effect can be attributed to the interaction of Pluronics with porphyrins in water solution. 相似文献

4He-p collisions at two values of4He momenta-8·6 GeV/c and 13·6 GeV/c — have been studied using the one-metre JINR hydrogen bubble chamber. Total, elastic and topological cross sections have been measured. The results are in agreement with other published data. The elastic differential cross section was compared with the predictions of the Glauber model formalism.Dedicated to Academician Václav Votruba on ths occasion of his eightieth birthday.We would like to thank Mrs. M. Stehlíková for drawing the figures. 相似文献

A comparative analysis of the inclusive production of 3H and 3He nuclei in 16Op interactions at a momentum of 3.25 GeV/c per nucleon is performed, and it is shown that the formation of these mirror nuclei occurs under close physical conditions, the distinction between their binding energies having no significant effect on the formation of the nuclei. 相似文献

The solubilization of europium β-diketonate complexes with amphiphilic polymers, ternary block copolymers of ethylene and propylene oxides (Pluronics), was shown to change luminescence intensity in such complexes. The association of europium β-diketonate complexes with Pluronics was proved by atomic force microscopy of agglomerates crystallized on mica surfaces from chloroform solutions of Pluronic F-127 in the presence and absence of the luminophores under study. In the absence of luminophores, Pluronic F-127 crystallized on a mica surface had a dendrite-like structure, while the evaporation of chloroform solutions containing both europium β-diketonates and Pluronic F-127 gave crystallized luminophore-Pluronic associates as compact islands with a characteristic size of ~0.5 μm. 相似文献
