Over the last decade a revolution has been taking place in nonequilibrium statistical mechanics [Physics Today, Sept, 2002]. This revolution is characterized by adapting the mathematical theory of chaos to nonequilibrium statistical mechanics. Fundamental new theorems and algorithms for computing transport coefficients have been derived. The CIs have played a key role in this revolution. We seek to broaden these developments by: generalizing a theorem which relates transport coefficients to chaoticity; detailed studies of the influence of thermostatting mechanisms on nonequilibrium chaoticity and fluctuations, and by understanding the range of applicability of a nonequilibrium fluctuation theorem for non-isoenergetic systems.

在过去的十年中，非平衡统计力学发生了一场革命[Physics Today，2002年9月]。这场革命的特点是将混沌的数学理论应用于非平衡统计力学。导出了计算输运系数的新的基本定理和算法。CI在这场革命中发挥了关键作用。 我们寻求扩大这些发展：推广一个定理，涉及到运输系数混乱;详细研究的影响，恒温机制对非平衡混乱和波动，并通过了解非等能系统的非平衡波动定理的适用范围。
