摘　　要：本文应用铱(Ir)作为信号元素制备示踪沙,并用中子活化分析方法检测信号元素的分布特征。在此基础上根据1988年8月现场测试结果探讨了天津港抛泥区泥沙运动规律。实验表明,天津港现行抛泥区的泥沙大部分背离航道向东北方向运移,对航道无明显回淤影响,该抛泥地的选择是合理的。Iridium (Ir) was used as signal element in tracer sediment preparations used in field monitoring of sediment movement trends in the Tianjin Port spoil ground in August of 1988. The distributional characteristics of the signal element were detected by using the neutron activation analysis method. Study results show that the greater part of the sediment in the spoil ground deviated from the ship channel and moved in a northeastward direction with no apparent silt back wash so the site selection of the spoil ground was considered favorable.
