To reduce the number of cross certifications, a special CA—bridge CA is specially used to build cross certifications with root CAs of every PKI domain. Through bridge CA, to set up trust relationship with other PKI domains, every PKI domain only needs to make cross certification between its root CA with the bridge CA.

但各CA之间相对独立、分散，缺少统一的管理与接口，各CA之间无法连通，信任无法传递，造成了较多的信任孤岛，给基于PKI技术的应用的拓展造成了很大困难，也限制了PKI技术的普及与良性发展。

In the spatial domain,canonical projection of the Wigner distribution function of the associated pupil function to show the insensitivity of the point spread function to the defocus-related aberrations is mainly used,and in the frequency domain,it is shown that the optical transfer function of such a system is also insens.

Let D be a bounded domain with C(1) boundary in Cn . The authors use the locally finite open coverring of the countable strictly pseudoconvex to define a new partitions of unity of σpoint finite local holomorphic , constructed a generalized Cauchy integral formula with discrete local holomorphic kernel on the bounded domain D and applied it to solving the 52equation.
