上海科技出版社出版的八年级物理“课标”教材第八章(压强)第四节(流体压强与流速的关系)中,为了让学生获得“流体流速越大压强越小”这个结论,设计编排了两个探究小实验,其中一个实验如下图1所示:1实验简述1.1教材编写者的意图通过实验探究显示:当用水管向模型小船中间水域喷水时,
In the eighth chapter (Pressure) of the eighth grade Physics “Course Standard” textbook published by Shanghai Science and Technology Press, the fourth quarter (the relationship between fluid pressure and flow velocity), in order to allow students to obtain “the greater the fluid velocity, the smaller the pressure ” This conclusion, the design of the arrangement of two small experiments, one of the experiments as shown in Figure 1 below: 1 experimental summary 1.1 textbook authors intentions through experimental exploration shows: when the hose to the middle of the model boat water,
