The DAL (dynamic adsorption layer) formation, that is, the establishment of uneven distribution of adsorption coverage over the rising bubble surface, with significantly diminished coverage at the upstream pole, is the factor of crucial importance for the bubble motion parameters and kinetic of the bubble collisions with various interfaces. The DAL presence can influence the stability of the thin liquid films formed by the colliding bubble at solution/gas and solution solid interfaces.
The purpose of this paper is to critically review the existing state of art regarding the influence of the DAL formation and existence on the bubble motion parameters as well as kinetics of coalescence at free solution surface and three phase contact (TPC) formation at solid/liquid interfaces of different hydrophilic/hydrophobic properties.
Despite the fact that up to now there is no direct experimental evidence showing DAL existence, it is documented by experimental data showing clear correlation between bubble local velocity variations and shape pulsations as well as lifetimes of the liquid film formed by the colliding bubble at gas/liquid and gas/solid interfaces.
DAL（动态吸附层）的形成，即上升气泡表面上吸附覆盖率的不均匀分布的建立，在上游极点处的覆盖率显著降低，是影响气泡运动参数和气泡与各种界面碰撞动力学的关键因素。DAL 的存在会影响由碰撞气泡在溶液/气体和溶液/固体界面形成的薄液膜的稳定性。
本文的目的是批判性地回顾关于 DAL 形成和存在对自由溶液表面上的气泡运动参数以及合并动力学以及不同亲水/疏水性质的固/液界面上三相接触（TPC）形成的影响的现有技术状态。
尽管到目前为止还没有直接的实验证据表明 DAL 的存在，但实验数据证明了这一点，这些数据表明气泡局部速度变化和形状脉动以及碰撞气泡在气/液和气/固界面形成的液膜寿命之间存在明显的相关性。
