摘要
本文介绍一种新的示踪泥沙运动的方法——中子活化天然泥沙示踪法。对天然泥沙进行中子活化分析,得到几十种作为天然示踪剂的元素含量值,这些数据经计算处理后,可以获得泥沙运动方向及相对输沙量等有关泥沙运动资料。在汕头港、上海港等地做了试验,其结果与常规水文测量符合得很好,并且有些结果是常规方法得不到的。
This paper presents a new method for tracing the movement of silt--tracing naturai silt by neutron activation. By analyzing the neutron activation of naturai silt, tens of elemental contents for the naturai tracer may be ob tained,and after carrying out computer operarton with those figures, all movement data including the direction of movement and relative discharge of so-lids will be settled up. Some tests have been taken for Shantou Port and Shanghai Port by using this method.lt was shown that all results were closely coincident with those data obtained from conventional hydrographic surveying, and some results are not obtainable by conventional method.
