摘要：

The etch-induction time, T(i), is measured for alpha-particles in CR-39 plastic track detector and the etch-critical time, T(c), is calculated for alpha-particles in CR-39 detector as a function of alpha-energy, E, and incident angle, theta. The etch-induction time was found to be independent of dip angle and directly proportional to the alpha-particle energy in the range from 1-6.1 MeV. The etch-critical time was found to be zero for angles greater than the critical angle, theta-c, whereas at angles less than theta-c, the etch-induction time, T(i), was increased by the value of T(c).
