本文综述了电加速方法的理论背景，并介绍了Chalmers工业大学电加速方法的发展现状。重点介绍了基于非稳态过程的快速方法，总结了非稳态方法的优点。本文报道了一种基于稳态过程的测量方法，并讨论了影响测量的一些因素。介绍了这些新方法在水泥和混凝土耐久性研究中的一些应用。平行试验结果表明，该方法与传统的浸入式测试方法吻合较好，但这种一致性有待进一步研究。
In this paper, the theoretical background of electrically accelerated methods is reviewed, and the current development of the methods at Chalmers University of Technology is described. The rapid method based on the non-steady state process is emphasized and the advantages of this non-steady state method are summarized. A study of the method based on the steady state process is reported and some factors which influence the measurement are discussed. Some applications of these new methods in the research work on cement and concrete durability are mentioned. Parallel tests show that the new rapid method corresponds well with the conventional immersion test, although fiwther study is needed to explain this coincidence.
