| Abstract: | This paper introduces the test calculation process of Pollution Endurance＇s DF coefficient.Through analyzing the effect that the stochastic errors of pollution test result in pollution endurance process act on the test calculation result of DF coefficient,it gives the probability of DF coefficient distribution range relative to the range of stochastic errors of pollution test value.Besides that it also mentions the methods that can reduce the effects of the stochastic error of pollution test value to test calculation DF coefficient. |
