| 摘 要： | 本文确切地指出了在真空中静压气浮轴承系统出现不稳定的原因。文中提出的一些适当的措施能够使轴承的环境压强维持在1±0.2左右大气压范围内,并消除轴承的自激振动。这样,既可以提高轴承的产品合格率,又可以提高具有静压气浮轴承的仪表的精度。 本文是在林同骥同志指导下完成的。

| Abstract: | The cause of instabilities in aerostatic bearing systems operated in a vacuum environment is studied in this paper. In order to eliminate this type of self-excited resonance, some pertinent remedies are suggested which can be used to maintain the ambient pressure of the bearing in a range of about 1±0.2 atm.. This will improve the performance of the instruments using aerostatic bearings as well as increase the percentage yield of qualified bearings.This work was done under the guidance of Prof, and Dr. T. C. Lin. |
