未建立起喷气燃料腐蚀变质预测预报机制。
The predicting mechanism of the degradation of jet fuels and the corrosion has not been set up.
除非它混同一些其他燃料，譬如汽油，而其结果就是腐蚀。 这将在几年的功夫里损坏引擎的密封条。
Unless it is mixed with some other fuel, such as petrol, the result is corrosion that can wreck an engine's seals in a couple of years.
产量很快就会遭遇“混合瓶颈”，即乙醇产量达到燃料需求量的10%；epa只允许燃料中最多混合10%的乙醇(乙醇更多将会对发动机造成腐蚀)。
Production will soon hit the "blend wall", when ethanol will meet 10% of fuel demand; the EPA allows blends of up to 10% ethanol (more might corrode engines).
