摘要：

The flow of electrolytes and non-electrolytes through narrow pores (about 1 nm radius) in synthetic membranes is reported. The characteristic features of such flow are the following. (i) The electrical conductivity displays fluctuations typical of single channel-like openings and closings. (ii) There is selectivity between anions and cations. (iii) The electrical conductance and flow of Rb+, Cl-, deoxyglucose or water is inhibited by the following ions in the order H+ > Zn2+ > Ca2+ > Mg2+. The similarity of the behaviour between flow through such synthetic membranes and transport across biological membranes is noted, and its significance to biological phenomena is discussed.
