In this paper we study the dispersion relation of thermal non-neutral plasma column by MHD theory. We use the dispersion relation to discuss the stability and dispersive properties in a non-neutral plasma-filled waveguide. The results are in agreement with those of cold non-neutral plasma. 相似文献

The overlap of magnetization of the giound state in a RKKY spin glass system with the Dzyaloshinsky-Moriya interaction is studied based on the theory of infinite number of order parameter. It is shown that the nonmagnetic impurities are coupled with the host lattice.The results are in good agreement with experiments. 相似文献

The dynamic network model taken into account the friction relative to incompressible effective viscous medium (EVM), the hydrodynamic interactions of a network with the EVM, and the interchain friction is considered. Two collective network relaxation spectra (RS) arise. The first RS corresponds to the network motion relative to immobile EVM, the EVM does not take part in this motion. The second RS includes the combined viscous motion of the network and EVM because of long-range hydrodynamic interactions. This RS is finite and narrow for infinitely large network. The symmetry of this motion is in concordance with that of incompressible EVM. The existence of interchain friction leads to the narrowing of both types of relaxation spectra. 相似文献

We discuss the problem of calculating corrections to the mean-field approximation in the Nambu-Jona-Lasinio model. To calculate
such corrections, we propose using the method of the Legendre transformation with respect to a bilocal source, which allows
taking symmetry constraints related to the chiral Ward identity into account effectively. Using the proposed method, we determine
the corrections to the quark propagator and the two-particle quark function.

设k,n1和n2是3个正整数,G=(V1,V2;E)是一个二分图,使得|V1|=n1,|V2|=n2,其中n1≥2k+1,n2≥2k+1并且n1-n2≤1.如果对任意不相邻的x∈V1和y∈V2,都有d(x)+d(y)≥2k+2,则G包含k个相互独立的圈.以上结果部分地回答了Enomoto提出的关于二分图有独立圈的问题. 相似文献

The structure and properties of active powder of discretely devulcanized rubber (APDDR) produced by the technique of high-temperature shear-induced grinding in rotary dispergators is studied. The morphology of APDDR particles, including such particles after mixing with hot bitumen, is examined by electron and atomic force microscopy. Rheological tests of rubber-modified bitumens demonstrate the efficiency of APDDR particles as an efficient modifier of bitumen binders and asphalt concrete pavements intended for service in different climatic zones under extreme loadings. The data are confirmed by field tests of modified asphalt concretes. 相似文献
