1981年以来,全国高考物理试卷先后4次考查游标卡尺,考查几率较高。而学生的得分率却较低。1933年始考20分度卡尺,全国通过率仅0.12,成为当年物理试卷中最难的一道试题。1994年第二次考查20分度卡尺,试题难度较1993年又有所降低。然而江苏省抽样分析结果,得分率也只有0.364,难度为全卷倒数第三。
Since 1981, the national college entrance examination physics paper has examined vernier calipers four times and has a higher probability of examination. The student’s score rate is lower. In 1933, he took a 20-degree caliper, and the national pass rate was only 0.12, making him the most difficult one in the physical examination papers of the year. In 1994, when we examined the 20-degree caliper for the second time, the difficulty of the test was lower than in 1993. However, the results of the sample analysis in Jiangsu Province, the score rate is only 0.364, the difficulty is the third lowest in the whole volume.
