摘要：
The effects of uniform rotation on the dynamics, equilibria and stability of cylindrically symmetric, radiating Z-pinch plasmas are studied. Rotation changes the Bennett and Pease-Braginskii equilibria qualitatively, eliminating radiative collapse for both quasisteady and dynamic plasmas. In particular, a steady rotating plasma column can support any current above the Pease-Braginskii value, with Ohmic heating balanced by radiative losses. Stabilizing effect of rotation on the m=0 mode of Rayleigh-Taylor instability of a hollow plasma shell was found for long perturbation wavelengths. (C) 1995 American Institute of Physics.
