摘要：

运用恒电量技术对冷却水系统的腐蚀进行监测,通过R_p、R_f、C_f 等电化学参数的分析,能够随时报道水处理各阶段的腐蚀变化,尤其是能够灵敏地反映出预膜膜层生长情况。

Abstract:

By acoulostatic pertur bation meter and a microcomputer as on-line measurem ent system, the cooling wate rsystems were mo nitored. Ba sed on the analysis of E-T attenuati on curves, relevant parameters, RpCd, R_f and C_f in equivalent circuit for the system, were obtained. Thus the corrosion of the systems could be reported at anytime, andin particular reflected sensitively was the situation of film forming at the stage of prefilming.

Key words: coulo static method, cooling water, corrosion monitoring
