Figure 15.

(a–c) Mean escape time distribution of 150 interactive molecules for different cavity and entrance-escape hole size for 10² runs; (d) best-fitting of Figure 15a is for a log-normal distribution; (e) mean escape time vs. the cavity ratio $\frac{h}{D}$. The time differentiation of molecular movements inside and outside cavities is provided by the dependence of the ratio $\frac{\mathrm{h}}{\mathrm{D}}$ on the waiting time τ, which for D=10² and 10³ nm cavities goes as a power law of the waiting time with exponent −0.5.
