Study of evaporation dynamics of liquid marbles at elevated temperature is essential to determine the feasibility of liquid marbles to be used as micro compartments for digital polymerase chain reaction (PCR). We have modified an existing theoretical model of evaporation of a liquid droplet and verified its applicability on the evaporation of liquid marbles. The evaporation dynamics of an individual and a group of liquid marbles are analysed. This paper demonstrates that the evaporation dynamics of liquid marbles obeys the theoretical framework for elevated temperatures. The evaporation of a group of liquid marbles are observed as a coupled function of their diameter, their number in a group, the vapour density of the surrounding atmosphere and their spatial distribution.
研究高温下液滴弹的蒸发动力学对于确定液滴弹用作数字聚合酶链反应（PCR）微反应室的可行性至关重要。我们修改了现有的液滴蒸发理论模型，并验证了其对液滴弹蒸发的适用性。分析了单个和一组液滴弹的蒸发动力学。本文表明，液滴弹的蒸发动力学在高温下遵循理论框架。观察到一组液滴弹的蒸发是其直径、组内数量、周围大气的蒸汽密度及其空间分布的耦合函数。
