Определение 
  Непрекъснат микро от първи ред 
  Sets Vector Space , . Then, for any ,  is a linear mapping of . If  to all linear mapping of  is . The  is a mapping from , if this mapping is a continuous map, it is called  Yes from  < SECTION> to  Continuously multi-mapped. Generally, all consecutive micromalable collections on  are generally recorded , so . 
 
 Непрекъснато микро от висок порядък 
  Set Vector Space , >  in  < / Section> The n-order Continuously Microprecognition is , which is the element exists in  exists and all elements in , ie ,  The component of  and . 
  корелационна теорема 
   Теорема на Клероре (1 поръчка)  
  set vector space , < Section> ,  When and only when all of the  exists and continuous. As you can see from this theorem, all consecutive functions of  can be recorded as . This combines the high-order continuous recursive definition of the previous high-end, and can obtain a continuous additional equivalent definition:  is from  to  Continuously can be micromaled, which means all of the biasing numbers of  exists and continuous.
