But in the moderate electric field 150 kv / cm , there is a sharp change in the configuration and charge distribution of the exciton , i . e . the exciton is directly split into an electron polaron and a hole polaron . the polarization and dissociation happen at a same time , which differs from that in conjugated polymers . and in the strong electric field 350 kv / cm , appear structural phase transition of the chain and luminescence quenching 同時得到兩個重要的臨界電場值： 1激子解離電場ec1 （ 150kv / cm ），在此電場下激子發生瞬間解離，成為電子型極化子和空穴型極化子； 2結構相變電場ec2 （ 350kv / cm ），在ec2下二聚化晶格開始被等距晶格取代， ptcl絡合物鏈發生結構相變，并伴隨peierls能隙漸趨消失和發光猝滅的現象出現。
The magnitude of the conductivity maximum increases and shifts to lower temperature with increasing sr content . in this paper , the electrical conductivity reaches maximum value at x = 0 . 4 . below the temperature corresponding to the maximum value , the electrical conductivity is found to follow the relationship for the small polaron hopping mechanism , charge compensation of oxygen vacancy dominates electrical conduction at high temperature , and oxygen vacancy acts as traps to catch carriers , resulting in the decrease of carriers concentration and mobility 通過電學和熱學性能測試結果表明，電導率隨著sr含量的增加以及溫度的變化都出現了極大值，在本論文中，在sr含量為0 . 4時電導率值最大，電導率最大值對應的溫度隨著sr含量的增加而降低，這是由于在低溫下以小極化子導電機理為主，在高溫階段則是氧空位的電荷補償占據主導作用，氧空位使得載流子的濃度和可動性減弱，從而導致電導率降低。
We have developed the theory of boundary shielding approximation of electric polarization , from which the values of spontaneous polarization of some typical ferroelectric materials can be derived . the shielded charges in ferroelectricity are in the state of surface bound polaron - dipole whose creation and annihilation must span a potential barrier . by introducing statistical method , four types of typical electric hysteresis loops of some common crystals and ceramics have been given , which are well consistent with the experimental results 利用電極化的邊界屏蔽近似，可計算出一些典型鐵電單晶的自發極化強度.鐵電屏蔽電荷處于表面束縛極化子偶狀態,其產生和湮沒要跨越位壘.由統計方法給出的一些常見晶體和陶瓷的四種典型電滯回線形狀，和實驗觀察到的結果一致
