摘　　要：利用异步效应的数学表达式,分析了异步效应与长期平均海面传递误差的关系。利用中国海区典型验潮站实测数据进行了异步效应及长期平均海面传递的数值计算,证实异步效应是影响长期平均海面传递精度的主要因素。In this paper, the mathematical expressions of asynchronous effect are used to analyze the relationship between asynchronous effect and long-term mean sea level （MSL） transferring error. The numerical computations of asychronous effect and long-term MSL transfer are made by using the observed data at some representative tidal stations in China Sea areas, and it is shown from the computed results that the asynchronous effect is the main factor affecting the long-term MSL transfer precision.
