| 1. | Since the isotropy of such laminates holds only for the elastic properties , but not for the strength behavior , their strength largely depends on the stacking structure
在板内发生损伤之后，其各向同性性质不再保留，最终强度将依赖于加载方向以及叠层顺序。 |
| 2. | Scientists have found a way to estimate an earthquake ' s ultimate strength by analyzing the initial seconds of a rupture - a step that could one day provide early earthquake warning
美国研究人员最近发现了通过分析地震发生之初的前几秒的震波大小，便可以断定出地震最终强度的方法，从而为未来总有一天能够早些提供地震警报迈出了一步。 |

| 4. | The ultimate strength of cf / ep quasi - isotropic laminates with different stacking sequences is experimentally and numerically investigated to study the influence of stacking structure or loading direction on the strength
摘要以碳纤维环氧树脂层合板为对象，研究了其最终强度与层合结构的关系，对于准各向同性层合板，其弹性性能不随方向变化。 |
| 5. | Thermomechanical treatment ( solution - cold - drawing - aging ) can increase alloys " strength greatly . the alloy in aging after cold - drawing was influenced by the interaction of precipitation and recrystauization . the precipitates not anly can strengthen the matrix but also can restrain recrystauization
形变热处理(固溶?冷拉?时效)工艺可大大提高合金时效后的最终强度，时效后形变热处理对电阻率影响很小。 |
| 6. | When 0 ? ply is included and lay on the surface in a laminate , the ultimate strength is the highest ; if a laminate does not possess both 0 ? ply and 90 ply , then it shows relatively large first - ply failure strength , but the ultimate strength is much smaller than that of laminates including 0 ply
拉伸试验和有限元数值分析表明：若板内含有0 ?层，且该层位于板的表层时，则最终强度最大；若板内既无0 ?层，又无90 ?层，则初始层破坏强度较大，而最终强度远小于含有0 ?层板的最终强度。 |
