摘要
从分析港口生产不平衡这一特征出发,详细分析了传统意义的不平衡系数存在的问题,进而指出在应用中存在的一系列错误。文中通过大量资料对到、离港的船舶流、车流以及货流的特征与规律,运用统计学原理进行分析,并经过假设检验,提出描述方法,确定正确认识与描述港口交通流的分布特征及港口生产状态特征的方法。
From the characteristic' s analyses of the production disequilibrium of the port, the problem is analysed in detail which is traditional disequilibrium ratio, some errors in use are further pointed out. Characteristics and law of the vessel flow,wagon flow and traffic flow are analyzed in use of statistical theory which amount of scientific data,and through hypothetical examination,descriptive method is presented.The method is assured which traffic stream's distribution and production state are surely known and described.
