1986年《医学物理》第三卷第三期发表的《用激光测定角膜混浊度判定死亡时间的研究》一文。文中的角膜相对透光率与死亡时间的关系式 _i=10~(a+bt),其物理意义不太清晰;数据处理误差较大,宜用最小二乘法进行直线拟合,才能获得最佳结果。设一束准直且光强I_o的激光垂直入射到吸收物上,载玻片上没有角膜时的透射光强I为 1986 “Medical Physics” Volume III, the third issue of “Determination of laser corneal opacity determine the time of death,” a article. The relative corneal transmittance and death time of the relationship _i = 10 ~ (a + bt), the physical meaning is not clear; data processing error is larger, it is appropriate to use the least squares method of linear fit, in order to obtain the most Good result. Set a bunch of collimated and light intensity I_o laser perpendicular to the absorption of the object, the slide without cornea when the transmitted light intensity I
