论文摘要
在本文中，我们表明，面对热蒸汽的意大利面条梁和色谱柱的弯曲揭示了年轻模量的时间演变，渗透意大利面条的水分子的扩散系数，水扩散的部分菲奇人行为，以及柱状弯曲角的逻辑样的演变。及时记录弯曲的几何形状，并通过处理图像获得幼年模量。我们以前应用了两个方程式，一个方程式用于梁弯曲，另一个方程式用于柱弯曲，以估计年轻的模量。实验是通过使用沸水中的热蒸汽来揭露自由悬挂的悬臂意大利面条和圆柱，以便将图像实时记录，而梁或柱不受干扰地弯曲。令人惊讶的是，水分子的估计扩散系数与其他人报告的实验数据非常匹配。该方法可能成为估计穿透材料的蒸气分子扩散系数的替代方法。
In this paper, we show that bending of spaghetti beams and columns exposed to hot steam reveals the time evolution of young modulus, the diffusion coefficient of water molecules penetrating the spaghetti, the partial Fickian behavior of water diffusion, and a logistic-like evolution of column bending angle. The bending geometries were timely recorded and the Young moduli were obtained by processing the images. We applied two equations proposed by us previously, one equation was applied for beam bending and the other for column bending, to estimate the Young moduli. The experiment was conducted by exposing the freely-hung cantilever spaghetti beams and columns using hot steam from boiling water so that the images were recorded in realtime while the beam or column bent undisturbedly. Surprisingly, the estimated diffusion coefficient of water molecules matched well the experimental data reported by others. This method may become an alternative for estimating the diffusion coefficient of vapor molecules penetrating the materials.
