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。我们的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.

更重要的是， 释放管道其余部分的油压可能会导致纸绝缘层内部形成气泡，可能会损坏它们并产生新的故障位置。
