1·The combat efficiency of fighter aircraft is calculated carefully, based on which the threat matrix is obtained.

计算了飞机的作战效能，在作战效能的基础上得到目标威胁矩阵。

2·The rules of measurement function for grade of target threat were established, evaluate matrix was defined to obtain multi-parameters unascertained measurement.

建立目标威胁等级测度函数规则，定义评价矩阵得出多参量未确知测度。
