NaCl溶液在磁场作用后的物理特性变化

摘要:

采用波长连续可调线偏振光透射光谱技术研究了在0.17T静磁场作用下NaCl溶液的光学特性的改变,同时利用接触角测量仪测量了经不同强度磁场处理20min后的NaCl溶液在硒化锌表面的接触角.实验研究发现,未经磁场处理过的样品和经过磁场处理的样品相比,它们的透射率及接触角呈现明显差异;入射光的偏振方向不同,同一样品的透射率也不同,入射光为P偏振情况下样品的透过率要大于入射光为S偏振情况下的透射率;同一磁场作用下,不同浓度的NaCl溶液的透射率差异明显;不同磁场强度下,磁场越强,NaCl溶液的接触角越小,说明溶液内部分子结构状态发生了变化.本文利用磁场与物质的作用特点简明地解释了经过磁场处理后NaCl溶液的透射光谱和接触角所发生的这些变化.

The contact Angle of NaCl solutions on the surface of ZnSe were measured by contact angle meter, and the so- lutions were treated by different magnetic field for 20 minutes. Simultaneously, the influences of magnetic field on optical prop- erties of sodium chloride solutions were studied by the continuous spectrum techniques of linearly polarized light in ultraviolet, visible and near-infrared areas. It was found that compared with the magnetic untreated solutions, the transmittance and con- tact angle of magnetic treated solutions presented obvious difference ~ the transmittance of the same sample was different when the polarization direction of incident light was different, for the case of P polarized incident light, the transmittance of the sam- ple was larger, compared with the case of S polarized incident light; under the action of the same magnetic field, the transmit-tance of NaCl solutions with different concentration were different obviously;the stronger the magnetic field was, the smaller the contact angle of NaCl solution was, it showed that the molecular inner structure of solution has changed. In this paper, the changes of contact angle and transmittance of NaCl solutions that treated by magnetic field were explained by the theory of elec- tromagnetic field interaction with materials.
