An efficient iteration-by-subdomain method (known as the Schwarz alternating algorithm) for incompressible viscous/inviscid coupled model is presented. Appropriate spectral collocation approximations are proposed. The convergence analysis show that the iterative algorithms converge with a rate independent of the polynomial degree used.

It was proved in the previous work that there must be a maximal possible accretion rate $ \dot M_{max} $ for a slim disk. Here we discuss how the value of $ \dot M_{max} $ depends on the two fundamental parameters of the disk, namely the mass of the central black hole M and the viscosity parameter α. It is shown that $ \dot M_{max} $ increases with decreasing α, but is almost independent of M if $ \dot M_{max} $ is measured by the Eddington accretion rate $ \dot M_{Edd} $ , which is in turn proportional to M.

Both java applet and flash were applied to emulate virtual panel of multi-channel pulse height analyzer (MCA), and Microsoft IE browser was used to control MCA through internet to measure the γ-ray energy spectrum of 137Cs. It Was shown that most of the work completed by applet can be done by flash too, and with flash, more beautiful panel of the remote controlled instruments can be easily designed.

Carvalho, Lucchesi and Murty proved that any 1-extendable graph G different from K2 and C2n has at least A（G） edge-disjoint removable ears, and any brick G distinct from K4 and C6 has at least A（G） - 2 removable edges, where A（G） denotes the maximum degree of G. In this paper, we improve the lower bounds for numbers of removable ears and removable edges of 1-extendable graphs. It is proved that any 1-extendable graph G different from K2 and C2n has at least x′（G） edge-disjoint removable ears, and any brick G distinct from Ka and Ce has at least x′（G） - 2 removable edges, where x′（G） denotes the edge-chromatic number of G. Key words 1-extendable graphs, removable ear, removable edge.

关键词： 1-extendable graphs removable ear removable edge.

In this article, distributions of internal stress and internal electric fields around a triple point of ferroelectric polycrystals generated by the spontaneous deformation and spontaneous polarization were investigated. It was found that when all three grains consist of a single domain, the internal stresses and the internal electric fields do not vanish. Though it may be determined according to the principle of energy, the spontaneous configuration will not be unique without involving other conditions due to the symmetry of the crystal structure.

The laser beam transmission can produce the laser-induced thermal index grating in polyatomic molecular materials. This grating effect has only a qualitative description in past published papers. In this paper we present a qualitative study of laser-induced thermal index grating and its relaation in polyatomic molecular *** optics bistability and degenerate four wave mixing arrangements, we have observed thermal index grating and its relaxation in nematic liquid crystales. The experiments were performed in solid, nematic and liquid phases of these materials. These experiments in solid phase of liquid crystals was performed and related physical mechanism was also discussed for the firsttime to our knowledge.

The critical concentration of lyotropic liquid crystalline phase transition for chitin derivatives was determined using a polarization microscope. The influence of molecular weight on critical concentration of liquid crystalline solution for chitin, chitosan, cyanoethyl chitosan and propionyl chitin successively increases as the chain rigidity decreases. Therefore it can be used as an indicator of the chain rigidity.
