preframe meaning in English

预装配

The basic elements of our approach to frames are contain in section one . a sequence of victors on a hilbert space h is called a frame if there are constants , such that as it ' s a important way to frame study by operators , we introduce preframe operator and frame operator associated with a frame { fi } i n and show corresponding relations between several frames and their preframe operators . also , we introduce some definitions such as similarity of frames , weak disjoint , disjoint and strong disjoint
第一节阐述hilbert空间一般框架理论，所谓hilbert空间h上的框架是指h中的一列元素{ fi正n满足： 3a ， b > 0 ， v正" ，有cx ， atiftl ’ ( < f ， fi > 1 ’三biif2 ii2 i = 1通过算子来研究框架是框架研究的主要方法，为此我们引入预框架算子和框架算子，并列出各种不同框架和其相应预框架算了之间的对应关系，为后文需要我们还列出了框架的相似，弱不交，不交和强不交的概念。
