无论天文学家、地质学家,从来未怀疑过地球的圆形会有多大变化。可是当分析地球大地构造力学几何图形时,发现地球表面以纬向褶皱较多而且很剧烈,如北半球有地中海褶皱,阿帕拉契亚褶皱;南半球有开普山褶皱,南极安第斯褶皱等。如果把这些褶皱南北拉伸,在体积不变的情况下,岂不是极轴变长了?如果把 No matter astronomers, geologists, have never doubted how much the circle of the earth will change. However, when analyzing geomechanical geometry of the Earth’s earth, it is found that there are more and more severe weft folds on Earth’s surface, such as the Mediterranean fold and Appalachian fold in the northern hemisphere, the Cape Mountain fold in the southern hemisphere, and the Andean Antarctic fold in the southern hemisphere. If these folds stretch north and south, in the case of the same volume, would not it be longer axis? If the
