| 摘 要： | 为研究微生物、氢渗透和阴极保护三者关系,介绍了微生物生长代谢的测定方法和氢渗透测试的研究方法。分别介绍了微生物生长曲线、菌量及代谢的测试方法。氢渗透测试主要采用Devanathan-Stachurski双电解池技术,试样常采用单面镀镍或镀钯处理,对阴极池施加阴极保护,试样表面产生的氢渗透到阳极池一侧后,利用恒电位仪记录试样表面氢的氧化电流即氢渗透电流。

| Abstract: | The paper aims to research the relationships among microorganism, hydrogen permeation and cathodic protection. Methods for the determination of the growth and metabolism of microorganisms and the research methods for hydrogen penetration tests were given. Methods for the determination of the population growth curve, bacterial count and metabolism were introduced separately. Devanathan-Stachurski double cell technology was adopted for the hydrogen permeation test. Samples were often treated with single-sided nickel or palladium plating. A cathodic protection was applied to the cathode cell. After the hydrogen produced on the surface of the sample permeated to the side of the anode cell, a potentiostat was used to record the oxidation current of hydrogen on the surface of the sample, that is, the hydrogen permeation current. |
