cooling efficiency的用法和樣例：
例句
- Exhaust and sprayed water manifold completely in stainless stet with high surface area cooling lack -et.
排氣管及歧管用高品質不鏽鋼材料，有極高的冷卻效率。 - And the spanwise cooling effectiveness is improved significantly when the distance between the two small coolant jets is longer and the blowing ratio is higher.
在各吹風比條件下，氣膜孔下游有射流小孔時，冷卻效率都有一定的提高，並且射流小孔間距較大時對兩氣膜孔中心線之間的橫向平均冷卻效率改善較大，吹風比較大時，效果更明顯。
