针对航空发动机滑油系统镁合金部件的工作环境特点，结合外场出现的滑油系统故障分析和返厂大修某发动机统计资料，发现微生物是引起其腐蚀的主要原因。
It is found that microbe can reduce magnesium alloy corrosion with analyzing its environment, the breakdown of its working system and the statistical data of repaired engine.
结果表明：供油调节系统故障对发动机正常工作有很大影响。
With a joint simulation flat of turbojet and its oil-supplied regulation system, three typical faults were simulated and evaluated with different model parameters and structure.
