An Experimental Study of Aspect Ratio on the Tensile Properties of an Elastic Fabric for Making-up of Pressure Garments

The“cut-and-sewn” pressure garments are normally tailored made in various sizes according to the size of human body as well as the area of burn wounds.When a tubular pressure garment is cut in different length and width measurements,different aspect ratio will be occurred on the elastic fabric for making up the pressuregarment. Many therapists in Hong Kong concerned the change of aspect ratio may affect the tensile properties of the elastic fabric and ultimately will affect the skin-and-garment interface pressure for the patient.The aim of     

Effect of Ecotype Carrier for Disperse Dye on Dyeing of Polyester Microfiber

The effect of "Eco" carrier SML for disperse dye on dyeing of polyester microfiber was studied. With respect of the result of effects of SML on dyeing rate curve, dye build - up, migration of dyed polyester microfiber and K/S, color property, color fastness of dyed polyester microfiber fabrics, SML has a significant application perspective, deserving practical uses.     

聚酰胺酰亚胺(PAI)的合成及改性环氧树脂/DDS体系研究(Ⅲ)TDE-85/PAI/DDS体系碳纤维复合材料的力学性能及断貌

考查了在TDE-85/DDS体系中加入不同端基,不同分子量的PAI后对其碳纤维复合材料性能的影响。结果发现,PAI的分子量在19 000～40 000范围内对复合材料的影响不大,而PAI有无活性端基和用量的影响却较大,并发现,加入20％未封端的PAI到TDE-85/DDS体系中所制得的复合材料的综合性能最好,其断裂韧性G_(IL)可提高63％左右,并且不影响其热性能,此外,还用SEM对复合材料断貌进行了分析。     

最小相位系统MRAS的工程设计法

本文给出适用于所有最小相位系统为被控对象的MRAS的简化工程设计方法,对于解决一般工程控制问题具有普遍意义.作为本方法的理论依据,文中给出一条定理及其数学证明.定理表明使用该方法设计的MRAS满足渐近超稳定性条件.文中还讨论了该方法的应用情况,从而论证了该方法的合理性和可行性.
