摘要
通过实验研究了静磁场作用下对水粘度、电导率和接触角的变化。结果表明,在静磁场作用下,水的粘度随磁场作用时间的增长而降低;同时,磁场强度越大,粘度降低得越快。水的电导率随磁场作用时间的增加而增加;水在铜表面上接触角减小了大约0.4°,在石墨表面接触角减小了大约2.4°。并得到了水在磁场作用下,发生上述性质改变的原因在于磁场影响了水中的氢键。
The influence of static magnetic field on the properties of water is studied systematically. From experiment results, it is found that, under the action of static magnetic field, the properties of water such as viscosity, conductivity and contact angels are changed. Viscosity of water decreases with the increase of processed time and the strength of the static magnetic field, and the conductivity of water increases when the time processed by magnetic field increases. Meantime, after processed by 0.40 T magnetic flied for 30 minutes, the contact angels of water on Cu and graphite are decrease about 0.4°and 2.4°, respectively. The essential reason of above phenomena might be that the hydrogen bonding in liquid water is influenced by the static magnetic field.
