摘　　要：In the 1960s Keldysh gave a formula for the photoionization probability of atoms in strong light fields as W=exp[-2|E_i|/ωf（γ）], （1） f（γ）=（1+1/2γ²） sinh^-1γ-（1+γ²）^1/2/2γ, γ=（2|E_i|）^1/2ω/ε, （2）where, ε is the amplitude of the electric vector of the applied laser and sinh^-1 stands for the inverse hyperbolic sine function. From this formula, he
