求翻译:Since the jet flow in its positive flow direction is add itionally slowed down by frictions and hence more kinetic energy is converted fromthe jet to the bucket, there is ηf < 0.是什么意思? 待解决

自喷铿俹在其积极瓦特铿俹瓦特方向加itionally减缓摩擦,因而更动能转换其外喷气桶,有畏F <0。

因为喷气机flow在它的正面flow方向是增加itionally由摩擦减速并且动能从喷气机被转换成桶,那里是 ηf < 0。

由于其积极的排放方向射流排放是添加 itionally 减缓下来摩擦,因此更多动能转换后的从喷射到桶里,有 ηf < 0。
