  7. Then mechanical experiments were carried out to measure the longitudinal tensile strength and radial supportive strength. based on the testing results, the different deformation functions of the tubular fabric were obtained and we conclude that the strength indexes vary directly as the material diameter and the arrangement of the pp and pgla has a prominent influence to the radial supportive strength of the woven artificial trachea. in addition, the degradation property of the tracheal prosthesis was investigated and this provides another important foundation for the fabrication technology of the artificial trachea

    在試驗測試部分，本課題對試樣的拉伸性能和徑向強度進行了測定，根據試驗的結果深入研究了每種管道織物在測試過程中的不同變形作用，也得到了不同的編織工藝參數對人工氣管力學性能的不同影響:原料的細度的變粗可增大人工氣管各力學強度指標;機織組織管道織物中兩種原料的排列方式對人工氣管的拉伸性能並無明顯影響而對其徑向強度影響顯著，其中以「 1隔1 」和「 3隔3 」的排列方式較佳。
