第一篇：几何分布产品的统计分析几何分布是离散型分布中最重要的分布之一，它在信息工程、电子工程、控制论及经济学中有着重要的应用。

For example, we use geometric distribution to describe the life distribution of runs of a species in transect surveys of plant populations and inventory demand distributions. In the theory of reliability, geometric distribution is one of the most important discrete probability distributions because of its loss of memory.

在可靠性理论中，由于几何分布的无记忆性，使得其是离散型寿命分布中最为重要的寿命分布之一，其相当于指数分布在连续型寿命分布中的地位，这正如程侃研究员在文献[5]中所指出的"在离散寿命的情形，几何分布起着连续情形下指数分布所起的作用"一样。
