These measurements are complemented by measurements of the flow field downstream of the cascade . the integrated losses and locations of secondary flow features with and without endwall film - cooling are determined for variations of both coolant supply pressure and injection location 以无端壁气膜冷却和有端壁气膜冷却两种情况进行研究，对比地获得了两者的综合损耗和二次流特征区域随冷却气体供给压力和注射位置的变化规律。
