( 2 ) on the leading edge, the film cooling effectiveness at the zone immediately downstream of the cooling holes is affected by blowing ratio and mainstream reynolds number, while the effects are not important in the downstream zone far from the cooling holes. ( 3 ) on the front half of pressure surface, the effectiveness increases with decreasing blowing ratio at the downstream near the cooling row and it is contrary at the downstream far from the cooling row. ( 4 ) on the rear pare of the pressure surface, the effectiveness decreases with increasing blowing ratio and does not vary so much downstream in the cases of higher blowing ratio
研究結果表明葉片吸力面端壁附近區域壓力系數分佈呈現出較強的三維特性，動葉吸力面尤其明顯；氣膜孔流量系數隨吹風比的增加而增大，在高吹風比情況下，流量系數逐漸趨于常數；在不同型面區域，冷卻效率分佈有較大的差異，而且吹風比與主流雷諾數的影響程度也不盡相同；低吹風比下，孔出口下游附近可以得到較好的冷卻，中、高吹風比下，冷氣射流在加速流動主流的作用下返回壁面進行二次冷卻，孔下游較遠區域可以得到較好的冷氣覆蓋。 -
For conventional high - speed mass production of flexible tubes, the skirt of the tube must be obtained directly by extrusion with a thickness at least six times lower, under conditions so that it is difficult or even impossible, to control the action of the blowing agent in the screw, then in the convergent zone of the extruder, so that a skirt is obtained with a expanded extruded layer with significant irregularities in thickness, which does not make it possible to provide an acceptable industrial packaging
對于軟管的常規高速批量生產，必須通過將管的厚度擠壓到至少為原來的六倍以下來直接得到管裙，在這樣的情況下很難甚至不可能控制膨脹劑在螺桿中，然後在擠壓機收斂段的運動，這樣，獲得的管裙具有厚度明顯不規則的擠出層，其不可能提供可接受的工業包裝。 -
