摘要
粘度是液体的重要物理性质,具有重大探究价值。在大学物理实验教学中,蓖麻油常作为研究对象,基于学者对蓖麻油粘度的微观理论研究较少,本文以Eyring反应速率理论为基础,根据牛顿粘度定律和液体溶液混合规则导出蓖麻油粘度方程并进行了间接验证,在微观上解释了蓖麻油粘度随温度的变化趋势,这对物理实验教学、加深对粘度的认识和理解都具有重大帮助。
The viscosity is an important physical property of liquid and to explore it has of great value. Castor oil is often used as the object of study in the university physics experiment teaching,considering the scholars very few researches on the viscosity of castor oil micro theory. In this work,based on the Eyring reaction rate, according to Newton＆#39;s law of viscosity and liquid solution mixing rules derived from castor oil viscosity equation and validated indirectly,thus explains the viscosity of castor oil as the temperature changes at the micro level,it is great help to the physical experiment teaching and deepen the understanding of viscosity.
