激光流量定义为单位面积的能量 ,即能量密度 ,简称流量。单位是Ｊ·ｃｍ - 2 ,或ｍＪ·ｃｍ-2 。发现有些教材和论文 ,将能量密度说成是激光生物剂量、激光剂量或治疗剂量等 ,我们认为不妥。激光生物剂量的定义是 :当生物体吸收激光能量后 ,将引起生物反应 ,直接对生物组织反应 Laser flow is defined as the energy per unit area, that is, the energy density, referred to as flow. The unit is J · cm -2, or mJ · cm -2. Some textbooks and essays are found, and we think it is wrong to describe the energy density as the laser biological dose, the laser dose or the therapeutic dose. Laser biological dose is defined as: When the body absorbs laser energy, it will cause a biological reaction, the direct response to biological tissue
