研究了采用电化学方法监测海水环境中金属表面微生物附着状态。根据钝金属在海水中开路电位随微生物膜形成正移的现象研制了不锈钢与Cu构成的微生物膜检测复合电极。它的电位差随微生物膜增长逐渐增大，标定后能够用于定量评价微生物膜生长程度。
The inspection of the biofilm attachment on metal surface in seawater was studied by electrochemical technique. in natrral seawater,the open - circuit potential of stainless steel was ennobled due to the biofilm formation on the metal surface,and has a linear relationship with the number of bacteria attached on metal surface.Taking into account the corrosion potential of copper was kept constant in seawater,a compound electrode was made with stainless steel and copper,and after demarcation it can be used to assess the attaching ability of microbes in different seawater media according to the change of the potential difference between the two metals.
