例句與造句

1. 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(fā)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(fā)生結構相變，并伴隨peierls能隙漸趨消失和發(fā)光猝滅的現(xiàn)象出現(xiàn)。
2. The result showed that the spin coating method was better relatively . the obvious blue shift of pl was found in spectra of the ps / pmma composite prepared with spin coating . compared to the spectra from original ps sample , the luminescence quenching was greatly decreased for ps / pmma composite due to the prevention to ps layer with coated with pmma film and modification of dielectrical penetrability of the medium in quantum threads by the pmma
   實驗結果表明，用旋涂法實現(xiàn)的pmma固化后再與多孔硅復合而制得的樣品的結果最好，它與原始的多孔硅樣品相比發(fā)光峰發(fā)生了藍移而且發(fā)光強度下降很小，我們認為pmma層有限的厚度和pmma對多孔硅表面的保護使復合后發(fā)光強度下降很小，而且制備的多孔硅pmma復合體系的發(fā)光強度幾乎不隨時間而下降。
3. It's difficult to find luminescence quenching in a sentence. 用luminescence quenching造句挺難的
