The specifics of energy exchange by nonrelativistic electrons (electron energy of ∼102–103 eV) during their travelling through a dielectric layer have been studied depending on the thickness of the layer applied
on substrates with different parameters. Electron travelling across a dielectric (pyrene) layer with a thickness of up to
10 nm deposited on a metal (bismuth) mirror is accompanied by the following effects dependent on the dielectric-layer thickness
and the electric parameters of the boundary: a nonmonotonic change in the pyrene luminescence intensity and variation in secondary
electron emission. 相似文献

A method of resonant near-field microwave probing is developed for contactless diagnostics of a high-pressure plasma. The
efficiency of this method in measuring the parameters of the plasma of an rf capacitive discharge in argon under atmospheric
pressure is demonstrated. The experimental results are compared with the data obtained using the independent method, the microwave
radiation “cutoff,” and with theoretical estimates. 相似文献

Mathematical modeling of a bimolecular chemical reaction in the liquid phase was carried out taking account of association of both reactants. The formally simple chemical reaction is thus transformed into a multistage process, which results in the formation of temporal dissipative structures. It was found that, apart from the usual dynamic modes, there appear oscillations of the concentrations of intermediates, characterized by two considerably differing periods. 相似文献

This paper reports on measurements in the 80–300-K temperature interval of the heat capacity at constant pressure C
p
(T) of high-porosity amorphous white pine carbon preforms (biocarbon) prepared by pyrolysis (carbonization) at T
carb = 1000 and 2400°C in an argon flow. The dependences C
p
(T) for biocarbon/copper composites based on the carbon preforms obtained have also been determined. It is shown that the mixture
rule holds for the composites, i.e., that C
p
(T) of the composite is a sum of the heat capacities of the constituent materials taken in the corresponding ratios. Phonon
mean free paths for the white pine carbon preforms prepared at T
carb = 1000 and 2400°C have been calculated and used to estimate the size of the nanocrystallites contributing to formation of
the carbon frameworks of these preforms. 相似文献

A rapid and reliable method for group identification based on the fragmentation of highly toxic O-alkyl-S-2-(N,N-dialkylamino)ethyl alkyl thiophosphonates using electron-ionization mass spectra was proposed. This method makes it possible to relate a test substance to one of the four groups of compounds containing two identical alkyl substituents at the nitrogen atom (methyl, ethyl, propyl, or isopropyl). The essence of this method is that the mass spectrum of the test substance is compared with the generalized mass-spectrometric patterns of each of the four groups of this class with the aid of a standard procedure utilized in the NIST information retrieval program. 相似文献
