【摘要】 介绍了基于电子海图的船舶操纵模拟器中采用的潮流仿真方法．其主要内容包括：广阔海域内流速场的仿真方法、受海潮影响的内河水道潮位及往复流的仿真方法、用于确定内河水道流向的三次多项式插值算法．此方法虽不能准确表现任意时刻和任意位置的潮流状态，但对于诸多海上活动的仿真或模拟来说仍不失为有实用价值的方法更多还原

【Abstract】 This paper dicusses some emulating methods on tide and current, especially in wide sea area and narrow waterway including the river affected by the sea tide. The methods are applied to the ship manoeuvring simulator based on electronic chart, and are proved useful.更多还原
