摘要
The center value of the Tropic of Cancer（ 23°26＇17″） is taken as the standard. The principle of the Tropic of Cancer passing through the country is that as long as the Tropic of Cancer crosses the territory administrated by the country,it is defined as the country crossed by the Tropic of Cancer regardless of the crossing size,any position and proportion. The definition is dominated by astronomical and geographical factors,and also involves historical and political causes. Via comprehensive analysis,it is determined that the Tropic of Cancer passes through 19 countries and regions around the world.
