摘　　要：汉明码校验是确保数据存储过程中数据完整性的重要技术。在教学过程中,汉明码校验方法中检测位取值是学生比较难以掌握的。为解决这一问题,提出一种改进的检测位取值方法。在保证计算结果准确性的同时,降低讲授难度,显著提升教学效果。同时以实例分析各项参数对改进后检测位取值方法的影响。教学分析与示例结果均证明,该方法具有较易的理解性,在教学分析中可以显著提高教学质量。Hamming code verification is an important technology to ensure the integrity of data in data storage.In the process of teaching,it is difficult for students to grasp the value of detection bit in the verification part of hamming code check method.In order to solve this problem,an im⁃proved method of detecting bit value is proposed.While ensuring the accuracy of the calculation results,the difficulty of teaching is re⁃duced and the quality of teaching is significantly improved.At the same time,an example is given to analyze the influence of various param⁃eters on the improved detection bit selection method.Both teaching analysis and example results show that this method is easy to under⁃stand and can significantly improve the quality of teaching in teaching analysis.
