| 摘 要： | 将研究晶态材料弛豫过程中粘度的唯象办法－四参数力学模型法与描述非晶材料的双能级模型统一起来，同时运用激活能谱理论对非晶材料弛豫过程中的粘度进行了唯象研究，得到了新的弛豫规律；并应用此规律对等温弛豫过程中的粘度进行了数值分析，得到了一些有用的结论。 |
| 关 键 词： | 非晶材料 粘度 结构弛豫 四参数力学模型 唯象研 |

| Abstract: | We have made unification between phenomenological method of four parameters mechanics model to study the viscosities of crystalline materials during structural relaxation processes and two-level model to describe amorphous materials and applied theory of activation energy spectrum to investigate the viscosities of amorphous materials during structural relaxation processes phenomenally and obtained a new relaxation law of viscosity. In the meantime, we have also applied above rule to make some numerical analyses for the viscosities of amorphous materials during isothermal relaxation processes and gotten some valuable results. |
| Keywords: | amorphous material viscosity structural relaxation four parameters mechanics model two-level model activation energy spectrum |
