\geq R_\sigma\; ,$$ monotonous decelerated bubble growth continues. At the same time, the role of Laplace pressure continues to decrease gradually, and the pressure $P_R$ inside the bubble approaches to a constant value equal to the external pressure $\Pi$. As it will be shown further, this process is rather protracted, so the concluding phase of the third stage, when the pressure inside the bubble practically does not change and the application of self-similar solution \[\[Grinin-Kuni-Gor\], \[Scriven-1959\]\] is possible, comes only in the interval of sufficiently large sizes of the bubble, when the condition $R \gg R_\sigma$ is satisfied with a certain reserve.

Sievert’s Law
-------------

Let us investigate behavior of bubble growth rate $\dot{R}$ with the increase of bubble radius for Sievert’s solubility law. From Eq. (\[Dyn-Eq\]) evidently stems. $$\label{Growth-Rate}
\dot{R} = \frac{D s}{R + R_\sigma} \left[ \zeta + 1 - \sqrt{1 + \frac{3}{2} \frac{R_\sigma}{R}} \right]\; .$$ Eq. (\[Growth-Rate\]) can be also written in the form similar to Eq. (\[Growth-Rate-Henry\]), to mark out three co-factors. The character of bubble growth rate is presented graphically in Fig. \[Fig:Rate\].
