有测量就有误差,误差教学是培养学生能力的有效载体.引导学生用“批判”的眼光发现并正视实验的系统误差,再想方设法予以修正以尽量消除它的影响,这既是误差分析的重要内容,也是从理性的角度进一步完善实验原理、设计更精确的实验方案的重要依据.误差分析可以让学生亲身体验发 There are errors in measurement. Error teaching is an effective carrier for training students’ ability. It leads students to use “critical” eyes to discover and face the experimental systematic errors, and then try to correct them to eliminate its influence as much as possible. This is an important content of error analysis. It is also an important basis for further perfecting experimental principles and designing more accurate experimental schemes from the perspective of rationality. Error analysis can allow students to personally experience
