摘　　要：分析主观判断值和船舶域模型在典型会遇局面下用作船舶碰撞危险判断指标时,与DCPA和TCPA的差别;在编程模拟船舶运动并比较其作为船舶碰撞危险判断指标的优缺点后认为,在开阔水域,船舶自动航行和避碰中使用DCPA和TCPA更适用;而在受限水域,用SJ值和船舶域模型来描述船舶碰撞危险更直观。The differences of the subjective judgment （SJ） value, ship domain model, DCPA and TCPA are analyzed, which are used as risk indices of ship collision in the typical situations. After program simulating ship＇s motion and comparing advantages and shortcomings of these risk indices of collision, the conclusion are drawn that DCPA and TCPA are more useful for ship preventing collision and automation of navigation in the open sea while the SJ value and ship domain model are more visual to describe the risk of collision in the congested waters.
