We studied the electric properties of phosphatidylcholine bilayers modified with crown ether (dibenzo[18] crown-6). The studies were carried out for various crown ether concentrations in forming solutions and various potassium ion concentrations in electrolyte solutions. The presence of crown ether in the membrane influences the membrane's impedance; there is a reduction in its resistivity, a decrease in its resistance of phase transfer and an increase in its capacity of phase transfer with an increase in crown ether concentration in the bilayer and in K(+) ion concentration in the electrolyte solution.
我们研究了用冠醚（二苯并[18]冠-6）修饰的磷脂酰胆碱双层膜的电学性质。针对形成溶液中不同的冠醚浓度以及电解质溶液中不同的钾离子浓度进行了研究。膜中冠醚的存在会影响膜的阻抗；随着双层膜中冠醚浓度以及电解质溶液中K⁺离子浓度的增加，其电阻率降低，相转移电阻减小，相转移容量增加。
