英文摘要：

Poly alpha-olefin （PAO） is one of the most widely used synthetic base oils. Comparing with other synthetic oils and mineral oil, PAO offer a lot of advantages including better high and low temperature performance, higher viscosity index, better thermal oxidation stability, lower pour point, higher flash point and longer service life. These excellent fea-tures make poly alpha-olefin has a large application market, especially suitable for aerospace, military, transportation and cosmetics industries. Narrates the application status of poly alpha-olefin in modern industrial synthetic lubricants, indi-cates the important development direction in the future.
