摘　　要：《普通化学》是高等农林院校各专业的基础必修课程之一,其教学内容经常会涉及数学知识和数学思维的运用,在教学过程中充分巧妙的运用数学知识和数学思维,可以使化学问题变得简单,从而会达到事半功倍的学习效果。文中通过“酸度对弱酸(碱)各型体分布的影响”——即“酸效应”的课堂教学具体实例,阐述了巧妙运用数形结合法解决化学问题的逻辑分析。通过教学反馈,发现巧妙运用数形结合法,可使困难的内容变得容易理解,更有助于培养学生的逻辑思维能力,激发学生的学习兴趣和创造力,从而提升学生的学习兴趣,提高学习效率。“General Chemistry” is one of the foundations of compulsory courses for all majors in higher agricultural and forestry colleges. Its teaching content often involves the application of mathematical knowledge and mathematical thinking. The full and ingenious use of mathematics knowledge and mathematical thinking in the teaching process can make chemistry problems simple and achieve the learning effect of twice the result with half the effort. In this paper, the influence of acidity on the distribution of various types of a weak acid(bases), that is, acid effect, is introduced to solve chemical problems by using the method of symbolic-graphic combination, which can enhance students’ interest in learning and improve learning efficiency.
