摘要：

We present a series of numerical and analytical computations on heat conduction for a strongly chaotic system-the Lorentz gas. Heat conduction is characterized by nontrivial features: While the heat conductivity is well defined in the thermodynamic limit, a linear gradient appears only for quite small temperature differences. The key dynamical feature inducing such a behavior is recognized as deterministic diffusion (along transport direction) which is usually associated to full hyperbolicity. [S0031-9007(99)08614-7].
