摘　　要：数值研究了混沌少体系统不可逆过程中的Jarzynski等式 ,并且比较了功和自由能之间的不等式关系 .发现Jarzynski等式不止在传统的统计力学适用范围———多体系统远平衡时成立 ,在混沌少体系统远平衡时也适用 .Jarzynski's equality in irreversible processes of chaotic few-body systems is investigated numerically and compared with the inequality relation between work and free energy. We find that Jarzynski's equality is valid for our few-body systems beyond the main field(many-body systems) for application of statistical mechanics driven arbitrarily far from equilibrium.
