摘　　要：本文论述了激光对生物组织的热作用的基本过程和作用原理,讨论厂生物组织对激光的吸收以及随温度的升高热作用在组织中的变化过程。提出了组织的比热、热导率、波长、功率密度、模式、光束的形状以及激光的脉冲宽度对热作用的影响因素。The theory and basic procedure of laser on the biological tissue has been described in detail in this paper. It also discuss the absorb of tissues for laser, and the changes of thermal function in tissue along with the raise of temperature. It bring forward that the specific heat, heat conductance, wavelength, power desity, model, shape of light and width of pulse has the effect to the heat function.
