摘要：

We show that the standard scenario of a highly tangled magnetic field in cluster cooling hows is consistent with observations and theory only under very restrictive nonrealistic conditions. This result implies that plasma instabilities (wave pitch angle scattering) are the most likely cause of heat flux inhibition in cluster cooling flows.
