近几年的中考物理试题,实验题所占的比例越来越大。初中物理实验的复习,是中考物理复习中的重点和难点。特别是在记忆实验器材,理清实验步骤等方面尤感困难。为此,结合测密度的实验向大家介绍一种巧用实验原理,复习初中物理实验的妙法。 In recent years, in the examination physics test, the proportion of experimental questions has been increasing. The review of junior high school physics experiment is the key and difficult point in the physical review of the examination. In particular, it is particularly difficult to memorize experimental equipment and sort out experimental procedures. To this end, combined with the experiment of density measurement, we introduce a clever use of experimental principles to review the subtleties of junior high school physics experiments.
