| Abstract: | This paper analyzes the discrete degree of random variable described by variation factor,and educes the relation between variation factor of the four common used probability in reliability engineering and distributing parameter. To demonstrate the application of the variation factor in reliability engineering, a sample, which describes numeric area of life variation factor in the different time effect modes of mechanical product and its parts is given. |
