对生存函数为F軈（x1，x2）=P（X1>x1，X2>x2）=exp - x1θ11#1！/ρ+ x2θ2121！/ρρ&ρ！ρ(，x1＞0，x2＞0，1≥ρ＞0，J！1＞0，J！2＞0的二元指数分布，讨论其参数的特征，给出尺度参数θ1与θ2相等检验方法并模拟结果。%The survival function for F(x1 ,x2)=P(X1>x1 ,X2>x2)=exp - x1θ11 21/!ρ+ x2θ21 21/!ρρ &!ρρ (,x1>0, x2>0, 1≥ρ>0,J!1>0,J!2>0 binary exponential distribution,the characteristic of its parameters is discussed. The test method for scale parameterθ1 andθ2 being equal and the simulation results are given.
