The filament winding angle when the fiber volume fraction of hoop orientation was equal to that of axial orientation was calculated 最后计算了轴向取向和环向取向纤维体积含量相等时缠绕角的值。
In application when we get the fitting result , we can calculate the principal conductivity value and axial orientation with those expressions 实际应用中只要将实验拟合的结果代入文中的公式,即可计算出主热导率的值和埋轴方位。
In the second part , we have mainly introduced a method for measuring the principal conductivity and axial orientation of thermally uniaxial material by ptr technology 在本文的后半部分,重点介绍了一种用ptr技术确定热单轴材料主热导率和埋轴方位的方法。
2 ) sbd was made using zno thin film as the active layer , which is a first time attempt . - 2 - a ) first time , high c - axial orientation zno thin film was deposited on al membrane supported on si substrate A )利用磁控溅射技术,首次在si衬底上,以金属al做过渡层制备具有高c轴取向的zno晶体薄膜。
With increasing blow up ratio , both the axial orientation and the crystallinity of tubular films increase . with increasing draw down ratio , only the axial orientation increases while the crystallinity does not change significantly 管膜的结晶度随吹胀比的增加而增大,当拉伸比增加时结晶度没有明显变化。
However , the cellulose chains of tubular films have obvious axial orientation with respect to the machine direction . moreover , the casting speed , draw down ratio and blow up ratio also have significant influences on the film mechanical properties and supermolecular structure 上述研究,对nmmo法纤维素膜的工艺条件、结构、性能和成形机理有了一个全面深入的认识,为该膜的进一步应用开发提供了实践指导和理论基础。
