| 摘 要： | 提出了一种基于MMG和船舶领域的LSP计算模型,以及改进的空间碰撞危险度（space collision risk index,SCRI）/时间碰撞危险度（time collision risk index,TCRI）模型,并进行了计算机仿真.结果表明：水动力模型精度可满足研究与实践要求;基于二分法的LSP模型能快速、可靠收敛;LSP和SCRI/TCRI模型更符合海员通常做法和避碰规则的公认理解.

| Abstract: | A new LSP model basis on MMG and ship domain theories and modified SCRI/TCRI model is presented and simulated by computer.The result show that the accuracy of hydrodynamic model is enough for studying and practice;Computing model of LSP by method of bisection is rapidly and reliably convergent during computing.New models are more accord with to rules and the ordinary practice. |

| Keywords: | ship domain hydrodynamic model method of bisection last steering point collision risk index |
