Through the iterative calculation steps of the mapping transformation method, it is proved that the mapping transformation method can avoid the occurrence of design verification points beyond the domain of random variables, and ensure the iteration convergence. On this basis, The expression of the average resistance and the corresponding resistance sub-coefficient of the application, the use of mapping transform method to calculate the average resistance of the iterative steps and the calculation of the formula.Examples show that the method to avoid the design check point beyond the random Variable definition domain, to ensure iterative convergence is effective and feasible, and easy to use computer programs.
