摘要
用固液分置法排除电气石自发电场对水的影响,研究了极性晶体电气石辐射的远红外线对水表面张力的影响规律。结果表明:电气石辐射的远红外线作用于水分子产生共振,可削弱水分子间氢键作用,从而使水表面张力降低。室温时,当电气石粉体的中位粒径(D50)为4.0～6.5μm时,随着电气石辐射远红外线对水作用时间延长,水的表面张力逐渐降低。D50为4.0μm,电气石粉体与水的质量比[m(t)/m(w)]不低于0.5时,随着辐射时间的延长水表面张力明显降低。D50为6.5μm,m(t)/m(w)为0.5时,水表面张力由初始值72.571mN/m降为72.049mN/m。
The influence of far-infrared radiation from polar crystalline tourmaline on the surface tension of water was investigated. The effect of spontaneous electric field of tourmaline was eliminated using soild-liquid seperation method. The results show that far-infrared rays from tourmaline resonate water molecules thus weaken the hydrogen bonds between them, therefore lower the surface tension of water, The surface tension of water decreased with the radiation time of the far-infrared rays from tourmaline grains with median diameter （D50） of 4.0-6.5μm. when D50 is 4.0 μm and mass ratio of tourmaline to water m（t）/m（w） is 0.5 or higher, the surface tension of water decreased obviously with the radiation time; when D50 is 6.5 μm and m（t）/m（w） is 0.5, the surface tension of water reduces from 72.571 mN/m to 72.049 mN/m.
