Builds a 2 - d transformation matrix in the xy plane
Builds a 2 - d affine transformation matrix in the xy plane
3 . through the realization of orientation picture showing in three - dimension , solve the problem that there is no way to show how rr , any located points exist in a little region when the located pictures shown in ichnography
The transport of reb is examined by 2d3v particle simulation in the xy plane . the filamentation and coalescence of currents and related magnetic field pattern , caused by the two - dimensional electromagnetic - beam - plasma ( embp ) instability , are observed
Using the two - stream fluid model , the linear dispersion relation is derived assuming a two - dimensional spatial geometry . two cases are considered , one is that the 2d spatial geometry is defined by the plane containing the two counterstreaming electron populations and the perturbation wave vector ( referred as the xy plane ) , and the other is that the geometry is defined by the plane being vertical to the two counterstreaming electron populations ( referred as the yz plane )
