ablation
의미: The removal or destruction of material from a surface, whether by surgical procedure, natural erosion, or thermal processes. In medicine, the targeted destruction of tissue, typically using heat, cold, or laser energy.
Ablation spans several fields. In cardiology, catheter ablation destroys small areas of heart tissue that cause abnormal rhythms such as atrial fibrillation. In glaciology, ablation refers to the loss of ice or snow from a glacier through melting, evaporation, or calving. In aerospace engineering, ablative heat shields protect spacecraft during re-entry by gradually burning away. The term collocates with 'cardiac,' 'laser,' 'thermal,' and 'zone.'
