例句与用法

1. In addition , the behaviors of the ptcl exciton in an applying electrostatic field were numerically explored . we came to the results that electric field has strong and interesting effects on the ptcl exciton . no dramatic polarization of the exciton is seen in weak electric field
   进一步研究激子对静电场的响应，发现静电场对ptcl激子的结构、电荷密度、电子能级均有明显影响，即电场能够降低ptcl激子的稳定性使其解离，并导致体系发生结构相变以及发光猝灭。
2. 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
   同时得到两个重要的临界电场值： 1激子解离电场ec1 （ 150kv / cm ） ，在此电场下激子发生瞬间解离，成为电子型极化子和空穴型极化子； 2结构相变电场ec2 （ 350kv / cm ） ，在ec2下二聚化晶格开始被等距晶格取代， ptcl络合物链发生结构相变，并伴随peierls能隙渐趋消失和发光猝灭的现象出现。
