A cellulose membrane was exposed to the static magnetic field (SMF) in the presence of KCl solution and ion transport through the membrane was measured before and after the SMF exposure. SMF at 0.24 T significantly enhanced the rate of ion transport, especially after the first exposure (p<0.05), while the increased ion transport rate did not return to the initial basal level after exchange of the aqueous medium. These results suggest that an irreversible, temporal conformation change took place on the cellulose membrane or on the water bound to the cellulose surface. The accelerating effect of SMF on the ion transport seems to have occurred as a result of stabilized hydration layer on the cellulose surface.
将纤维素膜置于KCl溶液中并暴露于静磁场（SMF），在暴露于SMF前后测量离子通过该膜的传输情况。0.24T的SMF显著提高了离子传输速率，尤其是在首次暴露后（p<0.05），而在更换水相介质后，增加的离子传输速率并未恢复到初始基础水平。这些结果表明，纤维素膜或与纤维素表面结合的水发生了不可逆的暂时构象变化。SMF对离子传输的加速作用似乎是由于纤维素表面水化层稳定所致。
