摘　　要：可变孔径超高真空盒系电子对撞机实施同步辐射装置扩建工程的关键部件。本文给出了不同孔径变化的８－环型波纹管在超高真空状态下电测应力实验结果。本实验选用了七个截面，布片较多，测出了不同截面的应力分布规律。同时，测出了装配应力对结构的影响。该测试结果为改进设计正式投入生产提供了可靠的科学依据。The aperture-changeable super-microvacuum for is a key component in an extension project for percussion set to implement synchronizing radiation.Strains have been measured in seven selected sections in super-microvacuum 8-pattern sylphon bellows with various apertures.The stress distributions in various cross-sections are determined and the influence of assembling stress on the structure iS also given.These results provide reliable information for further improvement the design and puthing the component into formal production.
