一、仪器装置1.末端呈水平的固定的弧型槽(用碰撞实验器的斜槽即可)固定放置在实验台边。2.一竖直平板,板上贴一白纸(白纸必须贴得非常平整)竖直固定在槽口旁。3.直径约为30毫米的钢球一只,正中轴线位置钻一孔,孔径约为8毫米,孔中固定一短毛笔头,笔头另一端露出一小段笔杆(用以跟笔头一端平衡,钢球的孔径视毛笔杆的粗细而定,如附图所示)。二、实验方法先将钢球放在弧型槽的水平槽口处,调整毛笔头与竖直板间的位置,使毛笔尖刚好跟板面相接触,并用
First, the instrument device 1. The end of the horizontal arc fixed slot (using the impact of the experimental slot can be fixed) placed on the experimental bench edge. 2. A vertical plate with a white paper (white paper must be very flat) is fixed vertically next to the slot. 3. A steel ball with a diameter of about 30 mm. Drill a hole in the middle of the axis. The hole diameter is approximately 8 mm. A short brush tip is fixed in the hole. A pen tip is exposed at the other end of the tip (used to balance the tip of the tip of the steel. The aperture of the ball depends on the thickness of the brush pen, as shown in the drawing. Second, the experimental method First, the steel ball is placed in the horizontal groove of the arc groove, adjust the position between the brush head and the vertical plate, so that the brush tip is just in contact with the board surface, and use
