摘　　要：提出了利用电子天平测量陶瓷材料密度及其气孔率的方法。这种方法是利用电子天平的清零技术,可减少传统方法的实验步骤。结果表明,利用电子天平测定陶瓷材料密度及其气孔率可提高工作效率,并保证了实验的精确度。The improved experimentation by using electronic balance to measure the density and the pore ratio of ceramic materials was designed. According to the Archimedes principle, the density and the pore ratio of the ceramic materials was determined in term of the liquid statics method. We improved the traditional procedure with the reset function of the exactitude electronic balance, and the results showed that the method could simplify the experimental process in the precondition of assurance about precision.
