摘　　要：用收益增长率来阐述企业收益的不确定性 ,发现杠杆作用不仅改变了企业收益增长率的波动范围 ,而且也改变了企业收益增长率的平均水平 .每股收益和销售量的增长率有相同的标准差系数 。This paper states the uncertainty of business income by the earning growth rate and discovers that leverages not only change the wave range of earning growth rates but also change the average of earning growth rate. The growth rates of the earning per share and the sales have the same coefficient of standard deviation, indicating that the leverage doesn't change the growth rates of the business relative risk.
