在物理总复习教学中，笔者常通过“一题多解”、“一题多问”、“一题多变”培养学生的发散思维。下面就容器中两部分气体间液柱移动方向问题的教学，谈谈在这方面的尝试。〔题目〕如图一，两端封闭、粗细均匀、竖直放置的玻璃管内有一长为h的水银柱，将管内气体分为两部分，且 In the physical review teaching, the writer often develops the divergent thinking of the students through “multiple explanations of one question”, “one question asked more” and “one question is more varied”. Let’s talk about the attempts in this regard with regard to the teaching of the direction of movement of the liquid column between the two parts of the gas in the vessel. (Question) As shown in Figure 1, a mercury column with a length h in the glass tube with closed ends, uniform thickness, and vertical position, divides the gas in the tube into two parts, and
