在这篇短文中,我们将研究碳纤维径向热膨胀系数α_r的测量。由于碳纤维的直径太小,它的径向热膨胀系数用常规方法是无法测定的。 测量是用装有加热炉的透射电子显微镜Teslab 613完成的。炉子的温度用相应加热丝 In this essay, we will study the measurement of the radial thermal expansion coefficient α_r of carbon fibers. Due to the diameter of the carbon fiber is too small, its radial thermal expansion coefficient can not be determined by conventional methods. The measurements were made using a transmission electron microscope Teslab 613 equipped with a heating furnace. Furnace temperature with the corresponding heating wire
