初二物理（人教版）第十章《压强液体的压强》第四节《连通器船闸》，这一节通过图１介绍船经过船闸从上游驶往下游的过程。用图示解释船经过船闸的过程存在的缺陷是不直观，学生不易接受。为此，我们做了一个船闸模型用于教学，取得了较好的效果。１制作材料取厚０．２cm无色?
The second chapter of Physics (PEP) is the tenth chapter “The Pressure of Pressure Liquids”. Section IV “Connected Ship Locks”. This section describes the process of the ship passing through the locks from upstream to downstream through Figure 1. The use of illustrations to explain the flaws in the ship’s passing through the lock is not intuitive and is not easily accepted by students. For this reason, we have made a ship lock model for teaching and achieved good results. 1 making material thickness 0.2cm colorless?
