The investigation was made of the dependence of the intensity of Tl, Ga, Mo, Mg, Mn, Sn, Bi, Ni, Zn, Pt and Au spectral lines and the plasma parameters (temperature T, electron concentration ne, degree of 6 ionnization α) from concentration of lithium additive. 相似文献

One-dimensional nonisothermal diffusion in ionospheric plasma (the F-region) is considered in the stationary case. The analysis is carried out for two species of positive ions with allowance for the ionization and recombination processes and the effect of gravity. A system of two coupled equations is derived for the concentrations of the electrons and ions. A transition is made to the case when the ions which determine dissociative recombination are impurity ions. For this case criteria are presented whose fulfilment causes the distribution that has been found to coincide with that obtained by Mange [9] without allowance for photochemical processes. 相似文献

We show the scattering matrix associated to the Manakov-Zakharov-Shabat (MZS) system can be factorized as the product of two scattering matrices associated to the Zakharov-Shabat (ZS) system of the Nonlinear Schrödinger (NLS) equation, whenever the initial conditions of the Manakov system have disjoint support. Moreover, if these initial conditions are assumed to be single-lobe, the eigenvalues of the MZS system are purely imaginary. 相似文献

《物理通报》创刊于1951年,到2021年已经走过了70年的历程.在旧中国,常年战乱,百业凋零,物理学界只有一本创刊于1933年的《中国物理学报》(1953年改称《物理学报》),仅限于发表高校物理学工作者的科学研究成果.新中国的建立,极大地焕发了中国人民的建设和创造热情.随着建设高潮的来临,急需团结全国的物理学工作者,加强物理学教育和广泛普及物理知识,把物理学这个所有理工学科的基础打得更加牢固.因此,中国物理学会通过广泛征求会员的意见,认为有再创办一个物理学刊物的必要,而这个刊物是建立中国物理学基础和推进中国物理学发展的重要措施之一. 相似文献

In this note we present an analytical study of the stability of the equilibria of the Rikitake system. We prove that the two non-hyperbolic equilibria of the Rikitake system are unstable for all positive values of the parameters. 相似文献
