Multiple regression analysis showed the octahedralshearstress 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; octahedralshearstress nonlinearly increases with the average main stress.
