Multiple regression analysis showed the octahedral shear stress may play a important role in increasing the cartilage surface roughness.
最后经迴归分析结果，Octahedral剪应力对关节面间粗糙度之增加有较显著之 影响。
The results show that strength of NEPE solid propellant under multi-axis stress state is related to strain; octahedral shear stress nonlinearly increases with the average main stress.
研究表明，多轴应力状态下NEPE固体推进剂强度与应力相关，八面体剪应力随平均主应力的增加呈非线性增加；NEPE推进剂的破坏强度随拉伸速率的增加而提高。
