| 摘要: |
| 以一个块体的理论运动轨迹特殊对象,分析在强中纬力作用下,地球板块在高纬度带(68°27'~90°00')、中纬度带(21°33'~68°27')、低纬度带(南纬21°33'~北纬21°33')内等不同地域的受强中纬力作用时的运动方向及其F-t关系图,以及板块在随着地球的自转,作跨越赤道的运动情况。结果表明:地球板块的运动特点随着纬度的变化而变化,强中纬力的主要控制因素为地球的黄纬;黄纬的变化发生在板块所受强中纬力变化的情况下,其外部现象表现为地球纬度的变化。这一结论为由特殊到一般的板块运动分析提供了理论依据。 |

| Abstract: |
| Based on some especial conditions,the migration direction and F-t cross map of the Plate under the high(68°27'~90°00'),middle(21°33'~68°27') and low(S21°33'~N21°33') latitude,the Earth rotation,and the migration of spanning Equator under the strong middle latitude force are analyzed The results showed that the Plate migration changes with the latitude. The ecliptic latitude is the major controlling factor of the strong middle latitude force. The change of the ecliptic latitude takes place under the strong middle latitude force in the Plate,and its external phenomenon shows to the change of Earth latitude. This provided a theoretic basis for analyzing in the Plate migration from individual to general. |
