The current was strong, a glass line of suction that streamed past the atoll, past the ghost ship, past the horizon, and the fat man fought it, arm over arm, call by call, but he could not overcome it.
The low slopes of the crystal and glass line segments of Figure 3 in comparison with the high slope of the liquid section reflect the fact that the coefficient of thermal expansion of a solid is small in comparison with that of the liquid.
This temperature dependence yields a normalized apparent activation energy (Ea/R) of approximately 13 kK for the mobility along the glass line.
Although the apparent activation energy along the glass line is the same within experimental error as the bulk, the aging rate is found to be slightly faster in the ultrathin film.
The mobility, on the other hand, is dictated by the relaxation time at the aging temperature, which increases during aging from the value on the initial glass line to that at equilibrium.
The length of the initial plateau is longer for the lower aging temperatures and is related to the increase in the relaxation time with decreasing temperature along the glass line, increasing approximately one decade for every 21 K.
