【摘要】 以主客体掺杂型DR1／PMMA（分散红1号／聚甲基丙烯酸甲脂）体系为例，通过表面电位等温衰减研究了材料极化后空间电荷的脱阱及异性电荷的补偿导致的衰减行为，由开路和短路的热刺激放电及电光效应实验探讨了样品内空间和偶极电荷的性质。更多还原

【Abstract】 Taking the guest-host DR1/PMMA film for example, detrapping and compensation effect for space anddipole charge of molecular dipole polymer electret with nonlinear optical property was studied by means of isothermalsurface potential decay method . The properties of space and dipole charge were investigated with the open-circuit andthe short-circuit thermally stimulated discharge current spectra .更多还原
