论文摘要
我认为水冷冻的动力学表明，在较小的零下温度下，（i）散装水环境中冰成核的时间是巨大的，因此不能在活细胞中的湖泊中发生。 （ii）冰核需要一些结合表面才能发生，但（iii）通常，这种冰成核可以仅在低于0oc的温度下才能发生。此外，我讨论了可以在开放式储层中大幅度降低近零温度下的冰核时间的因素，在开放式储层中，水与空气接触，在没有这种接触的细胞中。
I consider the kinetics of water freezing and show that, at small sub-zero temperatures, (i) the time of ice nucleation within the bulk water environment is enormous and therefore cannot take place either in lakes of in living cells; (ii) that the ice nucleation needs some ice-binding surfaces to occur, but (iii) even this kind of ice nucleation can take place, as a rule, only at the temperatures that are a few degrees below 0oC. Further, I discuss factors that can drastically reduce the ice nucleation time at nearly-zero temperatures both in open reservoirs, where water contacts with air, and in cells, where there is no such contact.
