| Abstract: | The exposure-control factors has been followed,at the same time,a discrimination-distribution factor has been introduced.According to the distribution of discrimination,the new item selectisn srategy to balance item usage exposure rate has been proposed.Suppose that ln1)and according to Monte Carlo simulation,the results show that the new approach has more preferably performance comparing with other approaches on several assessment indexes. |
