The behaviour of nonequilibrium fluids will be studied by combining ideas from liquid state theory, statistical mechanics and dynamical systems theory. This work will result in development and testing of mathematical expressions (Fluctuation Theorems) that are consistent with the Second Law of Thermodynamics, which determines the direction of any change in any macroscopic system, but are also applicable to microscopic systems. The expressions will determine the probability that finite sized systems will violate the Second Law for small periods of time and will therefore contribute to development of a fundamental understanding of microscopic systems and the development of nanotechnology.

非平衡流体的行为将结合液态理论，统计力学和动力系统理论的思想进行研究。 这项工作将导致数学表达式（波动定理）的发展和测试，符合热力学第二定律，决定了任何宏观系统中任何变化的方向，但也适用于微观系统。 这些表达式将确定有限尺寸系统在短时间内违反第二定律的概率，因此将有助于发展对微观系统的基本理解和纳米技术的发展。
