摘要: 介绍了测量热力学微正则系综中哈密顿动力学系统温度的一种新的动力学途径,即在各态历经性的假设下,温度可作为函数(H/‖H‖2)在能量面上的时间平均算出.这一方法不仅给出了确定温度的一种有效的计算途径,而且也提供了动力学系统理论和哈密顿系统的统计力学之间的内在联系. A new dynamical approach for measuring the temperature of a Hamiltonian dynamical system in the microcanonical ensemble of thermodynamics is presented. It shows that under the hypothesis of ergodicity the temperature can be computed as a time average of the function, ·(H/‖H‖ 2) , on the energy surface. This method not only yields an efficient computational approach for determining the temperature, but also provides an intrinsic link between dynamical system theory and the statistical...Abstract: A new dynamical approach for measuring the temperature of a Hamiltonian dynamical system in the microcanonical ensemble of thermodynamics is presented.
