摘　　要：本文对纯水及加抗冻剂的溶液在固化相变过程中的电势变化情况进行了实验研究。实验结果表明,加抗冻剂的溶液电势变化较缓慢平稳且峰值较小。文章就电势变化现象对抗冻剂的保护机理作了初步探讨。This paper focuses on several aspects of the electric potential variation in pure water and cryoprotective agent solutions during solidification. The results of the experiments show that voltages while frozen in cryoprotective agent solutions vary more slowly and stedily than in pure water. The mechanism of the effect of the cryoprotective agent is also discussed.
