DESCRIPTION:The fluxes and flux ratios of charged particles in
  cosmic rays are presented in the absolute rigidit
 y range from 1 up to 4000 GV. Of particular intere
 st is the energy dependance of the positron flux\,
  which clearly shows the existence of the new sour
 ce of high energy cosmic ray positrons. In the abs
 olute rigidity range ∼60 to ∼500 GV\, the antiprot
 on\, proton\, and positron fluxes are found to hav
 e nearly identical rigidity dependence and the ele
 ctron flux exhibits different rigidity dependence.
  The identical rigidity dependence of primary and 
 secondary cosmic ray nuclei fluxes will also be pr
 esented.
