The microwave permittivity of micro-coiled chiral carbon fibers and straight carbon nanotubes suspended in paraffin wax was studied at the frequency range of8. 研究了线圈状和麻花状两种典型螺旋形手征碳纤维以及直线形碳纳米管在8。
Rugs made from natural fibers make any room more earthy, the texture makes people feel like they almost came straight from the outdoors. 天然纤维做的地毯使房间更加古朴自然,它的质感让人们觉得好像刚从户外进来。
Results show that the oxidation resistance, hydrogen storage and electrochemical capacitance of the micro-coiled carbon fibers are superior to those of straight carbon fibers. 这些结构特性使得螺旋炭纤维在抗氧化性、储氢、电化学电容等方面都体现出超越平直炭纤维的优势和应用潜力。
This spinning method utilizes high-speed air-flow to separate the fibers, which make these fibers have better state of straight and more parallel than air-jet spinning, so the yarn strength can be improved more easily. 这种纺纱方法由于采用高速涡流辅助罗拉牵伸对纤维进行分离,充分利用了气流对纤维的良好控制,使得纤维具有伸直、平行度好的优点,有利地提高了纱线强度。
