The results show that Bi and Sb are mainly distributed on grains and grainboundaries, and Bi on grainboundaries there are mainly simple substance Bi particles, Sb in grains are intermetallics containing stibium.

For UOE tube with low springback stress,the Bauschinger Effect makes the yierld strength of flated specimen be lower than that of UOE tube body which received expanding process.In this case,Using plated sample as the body representation is safe and conservative.

对UOE管，由于其弹复应力低，包申格效应使压平试样的屈服强度低于经强力扩径强化的管体屈服强度，因而这种表征是偏于安全的。

This is necessary to make current design methods, which were developed for shap yielding steels with a yield plateau, applicable to such higher strength steels.

这是将现行的设计方法应用于这类高强度钢筋时所必须遵守的。现行的设计方法是按钢材突然屈服，而且有屈服平台的情况而制定的。

Such as we were we gave ourselves outright (The deed of gift was many deeds of war) To the land vaguely realizing westward, But still unstoried, artless, unenhanced, Such as she was, such as she would become.

我们怯于奉献使我们变得积弱，直到我们发现，其咎于我们自己我们对于赖于生存的国土不愿奉献却冀望马上在屈服中寻求救赎。

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。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
