摘要
研究了地图复制中图像变换的规律，给出了若干变换类型的数学模型。这些数学模型，已为计算实例和地图复制与印刷中的经验事实所验证。
The author studies the rule of image transformation in mapreproduction. Some mathematical models of image transformation are presented,which have been verified by the computation and the facts on map reproduction andprinting. Some examples are given.
