• 中文摘要： 本篇論文中主要是測量在空氣中的擴散係數,使用的方法是利用石英微天平測在史蒂芬管中質傳量的變化,由測得的結果可知,在一大氣壓下、溫度為298.17K及302.17K時,其擴散係數值分別為0.0706cm/sup 2//s及 0.072cm/ sup 2//s,略小於現有可查的兩組數據,而在這兩組數據中就約有9%的差距。
• 英文摘要： The purpose of the present study is to measure the diffusion coefficient for naphthalene in air. At the pressure 0.1013MPa, the diffusion coefficient for naphthalene in air is 0.0706 and 0.072cm/sup 2 //s at 298.17 and 302.17K, respectively. The diffusion coefficient was determined by a Stefan tube technique in which the mass flux is measured using a quartz crystal microbalance (QCM). The present values are smaller than two existing data and differ from each other by 9%.
