1 Erratum to: Acta Mechanica Sinica (2013) 29(4):543–549 DOI 10.1007/s10409-013-0063-9

• 1. The formula in the fourth sentence of the second paragraph in the section Simulations and methodology should read: $\phi (r)=4\epsilon [(\sigma /r)^{12} - (\sigma /r)^{6} ]$.

• 2. The two symbols $\varepsilon$ in the third paragraph of the section Simulations and methodology should be $\epsilon$.

• 3. The sentence right after Eq. (3) should read: where E(h) is the interaction energy of a single water molecule with a distance h from the substrate, $\rho (h)$ is number density of the water molecules per unit volume, and A(h) is the cross section area of the water droplet.

• 4. The integral expression in Eq. (4) should read:

  $$\begin{aligned} E(h)= & {} \int \limits _0^\infty {\frac{8\uppi }{{3\sqrt{3} a_{{\text {CC}}}^2 }}\phi \left( {\sqrt{r^2 + h^2 } } \right) r\mathrm{d}r} \nonumber \\= & {} \frac{{16\uppi \epsilon }}{{3\sqrt{3} a_{{\text {CC}}}^2 }}\left( {\frac{{\sigma ^{12} }}{{5h^{10} }} - \frac{{\sigma ^6 }}{{2h^4 }}} \right) \nonumber \\= & {} \left( {\frac{{5\sigma ^4 }}{{3h^4 }} - \frac{{2\sigma ^{10} }}{{3h^{10} }}} \right) E_\text {ads}. \end{aligned}$$

• 5. Equation (5) should read:

  $$\begin{aligned} \begin{aligned} E_\text {ads}&= E(h = \sigma ) = - \frac{{8\uppi \epsilon }}{{5\sqrt{3} }}\left( \frac{\sigma }{{a_\mathrm{CC}}}\right) ^2 \\&= - \frac{{8\uppi \epsilon }}{{5\sqrt{3} }}\left[ \frac{\sigma }{{(1 + \varepsilon )a_{\mathrm{CC}_0 } }}\right] ^2 \\&\approx - \frac{{8\uppi \epsilon }}{{5\sqrt{3} }}\left( \frac{\sigma }{{a_{\mathrm{CC}_0}}}\right) ^2 (1 - 2\varepsilon ). \end{aligned} \end{aligned}$$
