论文摘要
在本文中，我们报告了一项新的实验和理论研究，以检查在液体环境中沐浴在液体环境中对突然外部影响的软胶囊的响应。以蛋黄为例，我们发现软物质对翻译影响不敏感，而是对旋转，尤其是减速旋转的影响非常敏感，在此期间，离心力和膜的形状一起起着至关重要的作用，从而引起了柔软物体的变形。作为对同类研究的第一个研究，这一发现揭示了响应外部影响，揭示了膜结合软对象的运动和变形背后的基本物理学，例如蛋黄，细胞，软脑物质等。
In this paper, we report a novel experimental and theoretical study to examine the response of a soft capsule bathed in a liquid environment to sudden external impacts. Taking an egg yolk as an example, we found that the soft matter is not sensitive to translational impacts, but is very sensitive to rotational, especially decelerating-rotational impacts, during which the centrifugal force and the shape of the membrane together play a critical role causing the deformation of the soft object. This finding, as the first study of its kind, reveals the fundamental physics behind the motion and deformation of a membrane-bound soft object, e.g., egg yolk, cells, soft brain matter, etc., in response to external impacts.
