Figure 2. Variation trend of fragment number caused by impact of four high-energy particles on epoxy resin interface with different energy. ( a ) Changes in the number of H 3 O + particle fragments with different energies; ( b ) Changes in the number of NO + ion fragments with different energies; ( c ) Changes in the number of HO − ion fragments with different energies; ( d ) Changes in the number of O 3 − ion fragments with different
