1. First we go to watch the arciform movie. The movie's name , It is a strange world , there are many animals and beautiful scene. 首先我们看穹幕电影，电影是《阿拉斯加》，它是神奇的世界，有许多动物和美丽的景色。
2. One kind of beam type gas injection packing support plate used in the column is introduced. The curve equation of the developed pattern of the arciform plate is presented. 介绍了塔器内梁型气体喷射式填料支承及其拱形板展开图，并通过详细计算给出了该展开图的曲线方程。
3. The arch axis of arciform aqueducts formed by the continuum topology optimization method was compared with the circular arch axis and the parabolic arch axis of the same span. 结果表明，由结构拓扑优化方法生成的拱轴线，自重作用下的弯矩值以及相同均布荷载作用下的应力值都比相同矢跨值的圆弧拱轴线和二次抛物线拱轴线小。
