The failure reason of the aluminum alloy tube was investigated by macroscopic and microcosmic appearance observement, quality of material test, the stress analysis.
对失效铝合金管进行了宏观形貌观察、材质检验、 断口微观形貌观察及应力分析。
2
The boundary conditions were easily determined and controlled by the macroscopic models, while the gradient of water stress in the micro-zones of roots was ignored.
宏观根系吸水模型的边界条件容易确定和控制，但该类模型忽略了根系微域的水势梯度和其他类似现象。

Numerical examples give the macroscopic load-deflection curves and the stress-strain curves of typical soft tissues.
