“地球的公转运动”是高中地理最重要的内容之一。地球在公转轨道的不同位置有不同的光照图;在同一位置,从不同的角度观察,也会得到不同的图形。地球在公转轨道的某一位置,全球各地太阳高度的分布、正午太阳高度和昼夜长短的纬度分布、年变化和年变化值,都可转化为直观形象的图形。多次的图形转换,使同学们多角度、多侧面、全方位地获取对
“The Earth’s revolutionary movement” is one of the most important aspects of high school geography. The earth has different light patterns at different positions in the orbit; in the same position, different patterns are observed from different angles. In a certain position on the orbit, the distribution of the sun’s height, the height of the solar noon, and the latitudinal distribution of the day and night, the annual variation, and the annual variation of the earth’s altitude can all be transformed into visual images. Many graphic conversions have enabled students to acquire a variety of perspectives, views, and directions.
