| Abstract: | The convergency and stability of numerical solution in first order differential equation are studied in this paper. The optimal coefficients are determined, and strongly stable formulas in three-step linear methods are got. The practical calculations show that the results are better than parts in the linear methods. |

| Keywords: | numerical solution strongly stable optimization four-rank of three-step linear method |
