近十年的高考物理试卷和理科综合试卷中,电磁学的导棒问题复现率高达100%(除98年无纯导棒外),且多为分值较大的计算题,为何导棒问题频繁复现,原因是:导棒问题是高中物理电磁学中常用的最典型的模型,常涉及力学和热学问题,可综合多个物理高考知识点,其特点是综合性强、类型繁多、物理过程复 Nearly a decade of college entrance examination physical examination papers and science papers, electromagnetism guide rod problem recurrence rate as high as 100% (except for 98 years without pure guide rod), and more for the score of the larger calculation, why guide rod Recurrence of frequent problems because: guide rod problem is the most commonly used in high school physics and electromagnetism the most typical model, often involving mechanics and thermal issues, can be integrated knowledge of multiple physics college entrance examination points, which is characterized by comprehensive and diverse types, Physical process complex
