Both a generalized Doppler-shift relation and a generalized dispersion relation are first found,and the generalized intrinsic frequency with variety in dual values is directly correlated with the uniform currents.

Concepts such as broad sense relationship and its projection and gruncation, Vague relationship and its projection and gruncation are well defined in this paper, on the basis of which the one-to-one correspondence between Vague relationship and Vague map is demonstrated fully in detail.

The principal refractive indexes and dispersive relationship ofK_2B_4O_7·4H_2O crystal have been reported in this paper,its nonlinear opticaldoubling coefficient d_(25) was measured by Maker fringe s method.

On the basis of magnetic hydrokinetic equations,this paper calculates the dispersion relations of symmetrical unmagnetized cold plasma,and observes the transmission rules of electromagnetic waves in it by the dynamic PIC parti- cle simulation method.

The dispersion relations of spin waves in a ferromagnetic and antiferromagnetic materials bilayer system are investigated by taking the effect of the magnetic field and spin waves structure factor into account.
