前言 连云港位于江苏省东北角,海洲湾以南,是我国五大重点港口之一。为了适应四个现代化建设的需要,连云港的整治和扩建具有重要的经济意义。 在连云港物理模型进行试验的同时,我们开展了数学模型的研究。由于物理模型受到场所、设备、时间及劳力的限制,因此,寻找周期短花钱少的数学模型就势在必行了。因为数学模型在复演或预演水流现象时修改模型方便,能迅速提供多种方案供人们选择,因而它可与物理模型相辅相成,取长补短。
Foreword Lianyungang is located in the northeast corner of Jiangsu Province, south of Haizhou Bay, is one of the five major ports in China. In order to meet the needs of the four modernizations, the remediation and expansion of Lianyungang is of great economic significance. In Lianyungang physical model for testing at the same time, we conducted a mathematical model of the study. Because the physical model is limited by the location, equipment, time and labor, it is imperative to find a mathematical model with short cycle time and low cost. Because the mathematical model is convenient for modifying the model when rehearsing or rehearsing the water flow phenomenon, it can quickly provide a variety of options for people to choose from, so that it can complement the physical model and complement each other.
