Abstract：
A mathematical model LET = cZdRb for identifying space heavy ions is established based on energy loss rate of the heavy ions in CR-39. Coefficients of the model are acquired through correlative curves between linear energy transfer and residual range. Another relation VT = A∙(REL) E<350B between etched rate of CR-39 and restricted linear energy transfer of the ions, which is experimentally found, is used to connect the mathematical model for getting an equation R = A0.0455 Z3.18VT-1. Finally, an identification formula Z3.18=64541.08+2.53 (dR/dVT-1) is obtained by means of calibration experiments.
