A discrete probability distribution named as distribution of exponential difference is presented in this paper , formula to calculate the most probable success number , mathematical expectation and variance are derived for this distribution , relationship between this distribution and geometric distribution is discussed , a application of this distribution in markovian chain is given 摘要本文提出了一个离散型概率分布：指数差分布，推导了该分布的最可能成功次数、数学期望和方差，探讨了该分布与几何分布的关系，给出了该分布在马尔可夫链模型中的应用。
