Liquid marbles are non-stick droplets covered with micro-scaled particles. Liquid marbles demonstrate quasi-elastic properties when pressed. The interpretation of the phenomenon of elasticity of liquid marbles is proposed. The model considering the growth in the marble surface in the course of deformation under the conservation of marble's volume explains semi-quantitatively the elastic properties of marbles in satisfactory agreement with the reported experimental data. The estimation of the effective Young modulus of marbles and its dependence on the marble volume are reported.
液滴弹珠是覆盖有微观尺度颗粒的不粘液滴。液滴弹珠在受压时表现出准弹性特性。本文提出了对液滴弹珠弹性现象的解释。该模型考虑了在弹珠体积守恒的情况下，弹珠表面在变形过程中的增长，半定量地解释了弹珠的弹性特性，与已报道的实验数据吻合良好。本文还报道了对弹珠有效杨氏模量的估计及其对弹珠体积的依赖性。
