Physical examination of any swelling is the first step in making a diagnosis. Many a times we see a patient with a spherical swelling, which is usually a cyst. The interpretation of physical signs should be based on sound principles of physics. In the present paper, we explain physical characteristics of a swelling (cyst) using principles of fluid mechanics.
对任何肿胀进行体格检查是做出诊断的第一步。很多时候我们会见到有球形肿胀的患者,这种肿胀通常是囊肿。对体征的解读应基于可靠的物理学原理。在本文中,我们运用流体力学原理来解释肿胀(囊肿)的物理特征。
