聚合物在拉伸形变过程中,或者在机械力破坏条件下,如粉碎或碾磨,以及在热、声、光等各种能量对它进行破坏时,均伴随电子的激励现象。电子的激励在宇宙间任何地方均有电场或磁场存在,聚合物 Polymers are accompanied by electron excitation during tensile deformation, or under mechanical failure conditions such as comminution or milling, as well as damage to it by various energies such as heat, sound and light. Electron excitation There are electric or magnetic fields anywhere in the universe, polymers
