摘　　要：采用简化模型,将无纺静电纺丝纳米纤维膜中单根纤维进行重新排列,得到了由静电纺丝获得的纳米纤维膜和单根纤维拉伸强度间的关系。结果表明,纤维膜的拉伸强度与纤维膜的孔隙率、样品的尺寸(长度和宽度)和单根纤维的拉伸强度有关。通过与现有文献对比发现,简化模型得到的纤维膜的拉伸强度与实验得到的拉伸强度相差仅8.7%,验证了该模型的有效性,准确度更高。The relationship of tensile strength between an electrospun nanofiber mat and a single nanofiber was obtained by rearranging the single fibers in the nonwoven electrospun nanofibers.The results showed that the tensile strength of fiber mat was related to the porosity of mat,the size（length and width）of simple and the tensile strength of single fiber.Compared with the existing paper,it can be found that the tensile strength of fiber membrane obtained by the simplified model was only 8.7% lower than that obtained by the experiment,which verified the validity and accuracy of this model.
