英文翻译一下,谢谢!

Question

感谢贵司的回复，但我处仍有几个疑点：
1. 故障软管产生鼓泡的位置基本均为远离接头扣压端面的中间部分，并且在保压试验观察不到任何渗漏油的现象，可以排除软管两端连接位置扣压导致的原因。
2. 使用介质为15#航空液压油，不是空气。应该也不是空气渗透的原因。

为了进一步分析上次反馈的故障件软管，我司对客户退回的软管去除鼓泡表层后再次进行耐压试验，发现一个新的现象：在压力上升至25MPa，保压10min左右，表层出现潮湿的油脂现象，用纸巾或者油棉可以吸附下来；在压力卸荷后短时间内，表层的油脂又被反吸回去；在25MPa保压2h左右，表层的油脂集聚并出现一滴油液的渗漏，压力卸荷后，油液又被反吸回去。

另外，请贵司提供外层材料的材质，该层材质和哪些介质接触可能会导致表层鼓泡的故障？

Thank you for your reply, but I still have some doubts: 1 fault hose bubbling position basic is the part away from the joint press end, and in the pressure test is not observed that any oil leakage phenomenon, reason can be excluded from the ends of the hose connection position press lead. 2 using the medium of 15# aviation hydraulic oil, not the air. It should not cause air permeability. In order to further analyze the failure last time feedback hose, hose on the removal of our customers return the bubble surface again after pressure test, found a new phenomenon: in the pressure up to 25MPa, the pressure is about 10min, the surface appears the phenomenon of oil wet, with paper towels or cotton oil can adsorb down; in short time pressure unloading, surface grease and anti smoking back; in the 25MPa pressure is about 2h, the surface of oil leakage agglomeration and a drop of oil, a pressure unloading, oil is anti smoking. In addition, please the expensive department provides a layer of material, the layer of material and which media exposure may cause failure surface bubble?
