摘　　要：在激光医学领域,研究不同激光辐照参数对生物组织产生的效应是一个十分重要的课题,其中问题之一是实验研究各种组织的消融阈值。激光消融在临床医疗领域有着重要的应用前景。本文概述了消融阈值的物理含义,给出了消融阈值的定义,讨论了消融阈值与激光参数的关系。The investigation of fundamental problems plays a main role in understanding the effect of laser-irradiated parameters on biological tissue in laser medicine and surgery. One of these aspects is the experimental studies of the ablation threshold of various biotissues .The laser ablation has an important application foreground in clinical medicine. The definition of ablation threshold was summarized and its physics implications were provided. The relationships between ablation threshold and laser parameters were also discussed.
