查询词典 theory of evolution

For the aged aluminum alloys which generally contain disc/plate-shaped or rod/needle-shaped precipitates, a model has been established, from the viewpoints of thermodynamics, kinetics and strengthening theory, to relate quantitatively the yield strength to the size, volume fraction and aspect ratio of precipitates which all were analytical associated with the chemical compositions of alloys, aging temperature and aging time. This model has been experimentally proved to well predict the variation of yield strength with the evolution of disc/plate-shaped or rod/needle-shaped precipitates for present Al-4. 62wt% Cu-0.65wt% Mg alloy aged at 513K and Al-1. 12wt% Mg0.57wt% Si alloy aged at 463K, respectively, and the yield strengths simulated by this model were also found to be in well agreement with previously measured values for a series of aged Al-Cu binary alloys, AA6061 and Al-Zn-Mg alloys.

以析出热力学、长大动力学及强化理论为基础，研究了含有盘/片状、棒/针状时效析出强化相铝合金在时效过程中时效析出相尺寸、体积分数和长径比等参数的演变及其对合金时效强化效果的影响，给出了合金成分、时效变量与微观组织参数之间非线性的解析表达关系式，进而从微观结构—宏观性能相结合的角度出发建立起了具有盘/片状、棒/针状时效析出相铝合金的时效工艺—屈服强度量化模型，并将该模型应用于不同温度、连续不同时间时效下Al-Cu二元系列合金、6061铝合金和Al-Zn-Mg系列合金的屈服强度预测，得到了与前人实测值吻合良好的结果。

In order to describe in detail the structure of mesoscale atmosphere circulation and its evolution, symmetry theory are extensively used in the past fifty years. A large number of wind tunnel and water tank experiments are practiced to reshow the physical process that often appear in the atmosphere and, to some extent, successfully explain many atmsophere circulation characters in surface layer. But because of the planetary reflection and small Re number deformation, these physical experiments can' t represent real conditions of the atmosphere, they also can' t distinct viscous boundary layer separation and non-viscous dynamical separation as well as show the circulation response to surface diurnal heating.

为了详细描述复杂地形区域大气中尺度环流的结构和特征，过去50年来人们广泛采用相似理论，利用风洞和水槽实验再现大气中的物理过程，并在一定程度上成功地给出了大气近地层的一些环流特征，然而由于边界层反射和小Re数形变作用的影响，物理实验的结果并不能真实地再现大气中的实际状况，尤其是不能正确区别边界粘性分离流场和大气非粘性动力分离气流，环流场对地形下垫面日周期热强迫的响应过程也难以再现。
