The steady-state flow of a gas in a rough channel in the presence of strong transverse magnetic and electric fields is considered. It is shown that in this case there also exists a periodic regime consisting of a sequence of deceleration waves [5–7]. The periodic regime results from the action of the forces of resistance to the motion of the gas.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 1, pp. 152–158, January–February, 1989.The authors wish to thank A. A. Barmin and A. G. Kulikovskii for valuable discussions. 相似文献

The current equilibrium is investigated, where the generation of the Hall electric field on the magnetic Debye radius r B = B 0/(4πen e) is considered by the drifting of the relativistic electrons crosswise to the strong magnetic field. In this case, the electron propagation is possible at the distance d that is essentially larger than the electron radius of the backward reflection in the magnetic field r 0 ? m e v z c/(eB 0). The instability of the joint drift motion of ions and electrons is investigated for the frequency oscillation w much higher than the ion cyclotron frequency w Bi and by 4π n i m i c 2 ? B 0 2 and (k · B 0) = 0. It is shown that the resonance effects by the ion beam’s plasma frequency w ? kv 0 = w pi leads to the generation of the nonpotential perturbations with the characteristic increment Imw ~ 10?1 ÷ 10? 2 w pi. Estimates show that the instability, associated with the propagation of the high-energy ion beam through the strong magnetic field, can essentially be like the edge-localized mode in tokamaks. 相似文献

In this article, we consider the first initial boundary-value problem for an evolutionary system describing nonlinear interactions of electromagnetic and elastic waves. The system under study consists of three coupled differential equations, one of them is a hyperbolic equation (an analogue of the Lamé equations) and the other two equations form a parabolic system (an analogue of the diffusion Maxwell system). Existence and uniqueness results are established. We also prove the stability estimate of a weak solution. 相似文献

A four-step procedure to convert 4-(1-methyl-1-nitroethyl-1-ONN-azoxy)-3-cyanofuroxan into 3-(1-methyl-1-nitroethyl-1-ONN-azoxy)-4-aminofuroxan was developed. The pathways of transformation of the amino group of the synthesized compound into N-nitramino-, N-alkyl-N-nitramino-, N,N’-methylenediamino-, N,N’-methylene-N,N’-dinitramino-, and azo groups were studied. 相似文献

A method for synthesizing new compounds capable of releasing NO within living organisms, namely, 2-azidoethyl derivatives of methylenebis(1-oxytriaz-1-ene 2-oxides) bearing one or few 2-azidoethyl moieties, was developed. The synthesis involves nucleophilic substitution of the bromine atoms of the parent 2-bromoethyl derivatives of methylenebis(1-oxytriaz-1-ene 2-oxides) with the azide group. Some of the synthesized compounds are of interest as promising energetic materials. 相似文献
