摘　　要：通过对碘量法和多参数水质测试仪测定海水中溶解氧比对数据的系统误差检验,分析两种方法间系统偏离差异的显著程度。探讨多参数水质测试仪业务化应用的可行性,以在保证监测质量的前提下,切实提高监测工作效率。In order to improve the efficiency of monitoring, two methods to determine the dissolved oxygen in seawater by iodimetry and multi-parameter water quality tester were introduced. The significant differences between them were analyzed to identify the advantages and disadvantages of the two methods in practical work. The multi-parameter water quality tester could realize fast and accurate monitoring of the dissolved oxygen in seawater.
