A2 paper4 易错点
以上是经典力学的部分,大家的掌握程度貌似还可以。下面就是大范围的漏洞 以上是静电场和电容器易错内容, 接下来是磁场,也是你们的老大难问题 以上是大家最为薄弱的磁场内容,至少一题,多一点会出两条题目 量子力学内容非常容易猜测,要么考察光电效应,要么考察波粒二象性,要么考察吸收光谱和释放光谱,可能会结合在一起。 接下来的核物理比较简单,计算偏多 倒数第二就是Medical Physics了。 最后一个模块,宇宙学,计算不多。非常固定 谨以此推文,献给我在宝山世外的第一届毕业班的同学们: Boris, Carmela, Cindy, Charlie, Edwin, Elaine, Eric, Hank, Kevin, Vivian 感谢你们一直坚持到了最后,也感谢你们在三年里与我共同经历过点点滴滴美好的瞬间,留下了很多很多美好的回忆。我爱你们!
