Request stop climb at FL 220. 607. Our oil pressure reading is lower than normal.

请求在 FL 220 处停止爬升。607。油压读数低于正常值。

Even more importantly, relieving the  oil pressure from the rest of the pipe could allow gas bubbles to form inside the layers  of paper insulation, potentially damaging them and creating new places for faults to form.

更重要是， 释放管道其余部分油压可能会导致纸内部形成气泡，可能会损坏它并产生新故障位置。
