We believe the fine mechanical properties of tubular film are related to its fine chain orientation structure by using pole figure investigation and polarized fourier transform infrared ( ftir ) spectra analysis , the modes of orientation for flat and tubular films are obtained . it was found that the cellulose chains of the flat and tubular films have an uniplanar orientation mode with respect to the film surface 通過x衍射織構(極圖)分析和偏振紅外光譜分析建立了平膜和管膜的取向模型:平膜和管膜都有單平面取向;平膜中的分子鏈在膜表面內呈無規取向:管膜中的分子鏈則相對于拉伸方向有明顯擇優取向。

Firstly , a set of formula is developed for uniplanar x - and multiplanar xx - joints loaded with axial forces , in - plane bending moments and out - of - plane bending moments respectively . in china , it is the first time to develope a set of formula for full - width joints considering the membrane effect 在總結國內外研究成果的基礎上,本文對方管平面x型和空間xx型相貫節點在軸力、平面內彎矩和平面外彎矩等荷載工況作用下的靜力工作性能建立了一種更合理的理論簡化模型研究方法。

2 , in the experimental study , 12 joints tests are completed , including 5 uniplanar x joints loaded with axial forces , 3 uniplanar x joints loaded with in - plane bending , 4 multiplanar xx - joints loaded with axial forces , with the emphasis on the influence of and the existence of the out - of - plane braces , of which the multiplanar xx - joints tests is the first experiment project in china 其中,對等寬方管節點( = 1 . 0 )推求了考慮薄膜效應影響的極限承載力公式。 ( 2 )試驗研究:本文共計進行了12個方管平面x型和空間xx型相貫節點試驗研究,進一步加深對方管相貫節點的感性認識,了解其實際破壞模式。
