外加磁场对大庆油田污水和深井水表面张力的影响

THE EFFECT OF EXTERNAL MAGNETIC FIELDSON THE SURFACE TENSION OF DAQING'S WATER

在20℃条件下,研究外加磁场对大庆油田深井水和污水表面张力的影响,实验结果表明,表面张力与外加磁场强度呈非线性降低,降低的表面张力变化范围1～20％。经外加磁场处理的深井水和污水表面张力降低的效应可以保持10d以上。

<ABSTRACT>: The effects of external magnetic fields on the surface tension of Daqing's water have been investigated experimentally at 20癈. The results obtained show that the surface tension decreases nonlinearly with the external magnetic fields.The surface tensionrange of decrease is from 1% to 20% and these changes of surface tension of water treated magnetically can last for more than 10 days before it reaches the level of water untreated magnetically.
