   1. marked sets or target domains
      1. target domains
         1. = known domain + unknown domain
      2. the examples in marked sets:
         1. 0 marked： 0,00,000,0000,........
         2. 01 marked： ε,01,001,0001,........
         3. ... marked： .....................................

         5. 1 marked： 1,11,111,1111,........
   2. single set or complete sub-domain
      1. examples of elements in single set or in complete sub-domain: e.g.1. 0,1 e.g.2. Excited, Inhibition e.g.3. on,off
   3. hierarchical sets or super-sub-domains
      1. examples of elements and combination of elements in hierarchical sets or in super-sub-domains：e.g.1. 0,1 00,01,10,11 000,001,010,011,110,101,100,111 ............................................................................................ ................................................................................................................
