【摘要】 根据拓扑学中网的数学定义,证明了收敛于xi∈AX的网xiα和收敛于xi的地图符号qgf(xi)的网qgf(xi)α的存在,推导了可表达坐标网、水网、道路网等多种地图网络的数学定义。更多还原

【Abstract】 According to the mathematical definition of net in topology,the existence that netx of converge to xi∈AX and netqgf(xi)zα of converge to map symbol qgf(xi) was proved by the author.Mathematical definition of multi map nets that may express grid,water net and road net etc is given.更多还原
