Data obtained from the purified sample. (a) Conductance plot normalized by and (b) the resistance plot of the first plateau as a function of piezopositioner displacement , measured as the tube is pushed into Hg. The straight line in (b) is the fit given by . Here is one fitting parameter and is the other fitting parameter representing the resistance per unit length of the tube. In this example and .
