大气中发生的一切物理现象和过程都离不开大气的运动。大气运动对热量和水汽的输送影响着全球气温和降水的分布,制约着全球气候的形成。它是中学地理教学中的重点和难点。我研制的这个装置,能把复杂的大气运动现象,生动直观地展示出来,使学生有身临其境的感觉,收到了很好的教学效果。现将该仪器的制作以及演示方法介绍如下。1 仪器制作 如附图所示:用玻璃胶将厚玻璃板粘接制作成80cm×40cm×30cm的玻璃水槽,用氢氟酸分别在A,B,C处腐蚀直径为3cm的圆孔,方法是先取直径3cm,长5cm的塑料管,用蜡油分别镶于A,B,C处。然后用塑料
All physical phenomena and processes that take place in the atmosphere are inseparable from the movement of the atmosphere. The movement of heat and water vapor by atmospheric motion affects the distribution of global temperature and precipitation and restricts the formation of a global climate. It is the key and difficult point in the teaching of geography in middle school. The device that I developed can vividly and intuitively display the complex atmospheric movement phenomenon, so that students have the immersive feeling and have received good teaching results. The production and presentation methods of this instrument are described below. 1 The instrument is made as shown in the figure: glass glue is used to bond a thick glass plate to a glass sink of 80cm x 40cm x 30cm, and a circular hole with a diameter of 3cm is etched at positions A, B, and C with hydrofluoric acid, respectively. A plastic tube with a diameter of 3 cm and a length of 5 cm is first taken and set at positions A, B, and C with wax oil. Then use plastic
