摘要: 文中对材料在冲击波作用下发生极化或去极化过程，应用位错理论进行解释。导出了在冲击波作用下，计算材料极化率的公式。得出结论认为极化率不仅和位错密度有关，还和冲击波的频谱有关。Abstract: The polarization and depolarization processes in material under shock loading are interpreted by the theory of dislocation. The formula for calculating the polarizability under shock loading is derived in this paper. The conclusion is that the ppolarizability not depends upon the dislocation density but also upon the spectrum of the shock wave.
