目前,中学地理教学中缺乏立体、动态的模型用于演示火山喷发,只能通过一些二维的图像、flash动画或文字叙述来解释其过程。即便是实体演示模型,也主要是静态的火山结构模型,仅能展示火山的内部结构,不能动态地演示火山喷发过程中岩浆的运动状态。为此,制作一个可以清晰展示火山活动过程的动态模型非常有价值。通过动态演示模型,可以让观摩者更加直观地了解和学习火山喷发的过程,加深对火山结构、喷发原 At present, there is a lack of stereoscopic and dynamic models in geography teaching in middle schools for demonstrating volcanic eruptions, which can only be explained by some two-dimensional images, flash animations or narration. Even the physical demonstration model is mainly a static volcano structural model, which can only show the internal structure of the volcano and can not dynamically demonstrate the movement state of the volcano during volcanic eruption. For this reason, it is very valuable to make a dynamic model that can clearly show the process of volcanic activity. Through the dynamic demonstration model, allowing viewers to more intuitive understanding and learning volcano eruption process, deepen the volcano structure, eruption of the original
