- Possible affective RE of observation target (independent variable) accounted for 280 items. 可能影響RE的觀察指標（自變數）共280個。
- High temperature, the morning Nov Dec point, 2:00 pm, the whole person lying on the floor observable target, the elbow is blistering, and burned. 高溫，早上十一十二點，下午一兩點，整個人趴在地上瞄靶，整個手肘都起泡了，燙傷了。
- A Hough transform-based track-before-detect (TBD) algorithm is used to detect low observable target with constant velocity in K-distributed clutter and thermal noise. The target model adopted is Swerling II. 在K分佈雜波加熱雜訊背景下 ,採用基於Hough變換的檢測前跟蹤演算法對勻速直線運動的SwerlingII型低可觀測目標的檢測過程進行了模擬。
- Having the back showing or in view of the observer. 背面的顯露出背面的或背對觀察者的
- They sent her there as an observer. 他們派她去那做觀察員。

- He fired several shots (at the target). 他向目標射出了幾發子彈。
- As most of non-coherent radar on active duty has no or little clutter cancellation ability,whenever flying targets enter the area of ground clutter,it is very difficult for radar to observe targets. 由於大多數非相參體制雷達沒有雜波對消能力或雜波對消能力較差,一旦各類飛行目標進入地雜波區,雷達就難於觀測目標。
- I aimed at the target but hit the wall. 我瞄準了靶射擊,但卻打在了牆上。
- The movable target on a leveling rod. 視准器水準尺上可移動的目標
