The results of simulations performed at nearly zero temperature demonstrate that stress-induced phase transitions from body-centered cubic to face-centered cubic and hexagonal close-packed structures take place during the deformation process of both Fe and Ta, and the maximum fraction of FCC atoms varies linearly with the tensile strength, from which we can conclude that a critical stress exists for the phase transition to take place.

低温模拟结果表明，纳米晶铁和钽在变形过程中都出现了应力诱导的相变，其中FCC结构含量的最大值和抗拉强度成线性关系，并由此可以推出相变发生的临界应力值。

Then, an ideal random-packed-sphere model with simple cubic, body-centered cubic and face-centered cubic structures is presented to predicate the specific protonic and electronic conductivities of the catalyst layers. A correlation equation of the specific conductivity is obtained and the model is validated by the good agreement between the calculations and the measured data.

然后，分别用简单立方、体心立方和面心立方三种自由堆积球结构首次建立了描述催化层有效质子和电子传导率的理论预测模型，分析了电解质本体电导率、球半径、接触系数和接触角对质子传导的影响，得出催化层有效质子和电子传导率的计算公式，模拟结果与实验数据吻合良好，证实了模型的有效性。
