化学实验与科学技术的进步密切相关,数字显示器就是一种与现代科学密切相关的新兴技术,具有便捷、直观、实时、准确等特点,是中学化学实验改革和发展的有效手段。在中学化学教学中采用数字显示器,不仅能促使学生了解先进的科学技术,还能获得科学的学习态度,形成正确的学习方法。在中学化学实验室里,一般都配有数字测温计、数字pH计、电子台秤等数字显示器,这些数字显示器在中学化学实验教学中将发挥越来越重要的作用,也将使化 Chemistry experiments are closely related to the progress of science and technology. Digital displays are emerging technologies closely related to modern science. They are convenient, intuitive, real-time and accurate, and are effective means for the reform and development of chemistry experiments in middle schools. The use of digital displays in chemistry teaching in secondary schools not only enables students to understand advanced science and technology, but also obtains a scientific learning attitude and forms a correct learning method. In the middle school chemistry laboratory, digital thermometers, digital pH meters, digital scales and other digital displays are generally provided. These digital displays will play more and more important roles in the chemistry experiment teaching in middle schools,
