摘 要: 对重力加速度的测量、混色效应的观察、物体沉浮的演示、滑轮组、压力与液体沸腾温度的关系和小平板的固定等六个演示实验进行制作和改造,以期提高演示效果. For the purpose of improving the effect,the author had improved six demonstrations,based on the authors longterm working experience——the measure about acceleration of gravity,the observation about mixing colors effect,ups and downs of object,pulley block,the relation between pressure and boiling temperature of liquid and fixation of a small flat.
