  deterministic expression
Numerical simulations of the stochastic time evolution of biospecific interactions are described and show that when molecular populations are large, time course predictions match those obtained using a deterministic expression.
      


Measurements were carried out in a running tunnel of Beijing subway to obtain the dynamic responses at some specified points on the tunnel lining and also on a ventilation kiosk nearby. A frequency spectral analysis was performed and a simulated deterministic expression of train loading was obtained by analysing the vibration of the carriage system. FEM was then adopted to study the dynamic behaviour of the tunnel-mass system. Results indicate that the calculated acceleration components at some specified...

Measurements were carried out in a running tunnel of Beijing subway to obtain the dynamic responses at some specified points on the tunnel lining and also on a ventilation kiosk nearby. A frequency spectral analysis was performed and a simulated deterministic expression of train loading was obtained by analysing the vibration of the carriage system. FEM was then adopted to study the dynamic behaviour of the tunnel-mass system. Results indicate that the calculated acceleration components at some specified points agree with that of the measured well enough. Some quantitative values of the responses are also predicted.

>=In the present paper, a model to calculate the thermodynamic functions of the whole nanocrystal has been developed on the basis of the dilated model and the universal equation of state. The deterministic expressions of the enthalpy, entropy and Gibbs free energy as functions of the excess volume of interfaces, temperature and the grain size have been derived. Applying the thermodynamic model, the temperature and the critical grain size of phase transformation can be predicted precisely for the nanocrystalline materials. As an example, the parameters of phase transformation are calculated for the Co nanocrystal. The calculation results of the present model agree well with the experimental findings. It has been predicted from our work that the high temperature phase will be stably exist when the grain size is reduced to less than 10nm.

在应用界面膨胀模型和普适状态研究纳米晶界面热力学特性的基础上,发展了纳米晶整体材料热力学函数的计算模型,给出了以纳米晶界面上的原子分数作为权重的纳米晶体单相材料的焓、熵、自由能随界面过剩体积、温度以及晶粒尺寸发生变化的明确表述式.由此可以定量预测纳米晶材料发生相变的特征温度和临界尺寸.并以Co纳米晶为计算实例,对其相变参量进行了预测,计算结果全面证实了已有文献报道中的实验结果.由此,可以预测晶粒尺寸降低到几十纳米以下时,材料高温相的热稳定性将会增强.
