摘　　要：用惠更斯作图法推导光轴在入射面内的正单轴晶体e光全反射角公式：i=arcsin(1/n)((n_e^2-n_o^2)sin^2α+n_o^2)^(1/2),它与光轴在入射面内的负单轴晶体e光全反射角公式形式完全相同；所以光轴在入射面内的单轴晶体e光全反射角公式为i= arcsin(1/n)((n_e^2-n_o^2)cos^2α+n_e^2)^(1/2)=arcsin(1/n)(n_e^2-n_o^2)sin^2α+n_o^2)^(1/2)(简称“何波公式”)。The extraordinary light total reflection angle formula of positive uniaxial crystal for the optical axis in incidence plane is deduced by using Huygens principle： arcsin 1/n√（n^2e-n^2o）sin^2α＋n^2o The form of this formula is same as the extraordinary light total reflection angle formula of negative uniaxial crystal for the optical axis in incidence plane. Therefore,the extraordinary light total reflection angle formula of uniaxial crystal for the optical axis in incidence plane is i=arcsin 1/n√（n^2o-n^2e）cos^2α＋n^2e=arcsin 1/n√（n^2e-n^2o）sin^2α＋n^2o,which is simply called ＂ He Bo＇ Formula ＂
