摘　　要：设计制作了能对水下大型钢铁构筑物直接测试的小孔限流型腐蚀传感器 ,讨论了影响其测试面积的结构因素 ,设计了相应的测试仪器 。An electrochemical sensor constraining the measuring current through a pinhole for directly monitoring/detecting corrosion of marine steel construction was designed and made.Props with powerful magnetic magnet and a retractable tentacle were employed to fix on the surface of ferromagnetism metal material such as iron and steel and to ensure the electricity contact.The influence of structure parameters on its measurement area were discussed.A set of instrument fitting field measurement,based on the control of single chip computer was designed and made.The field measurements on bare steel tubular stakes of No.27 container berth in Tanggu were successfully conducted,and the suitability of the designed system in the circumstance of field corrosion monitoring/detecting was proved.
