A new emission peak located at long wavelength (at about 515 nm) appeared in PL spectra of the unsubstituted polymer (PF6P) films annealed in air, and the intensity of the long wavelength emission increased with the increase of annealing temperature or annealing time.

苯环上未取代聚合物PF6P的薄膜在空气中退火后在长波(515 nm)出现一个新的荧光发射峰，随退火温度的升高或退火时间的延长，该长波荧光发射峰的强度逐渐增大，薄膜的紫外吸收峰变宽。

The electrophysiological remodeling in left ventricle usually display prolongation of action potential duration which improve the high ununiformity of repolarization so that there occur more reentry and the incidence of early after depolarization and delayed after depolarization.

左心室的电生理重塑通常表现为动作电位时间(action potential duration，APD)延长，从而增加了复极的高度不均一性，容易发生折返，同时也增加了早后除极和延迟后除极的发生率。

Results Using different concentrations of 5fluorouracil to deal with A549 cells, with the increase in drug concentration and treatment time,cell survival rate decreased significantly;and low concentration of 5fluorouracil induced the cell spread and increased vacuolization within the cytoplasm, acridine orange staining showed an increase in acidic vesicles,high concentration made the cell round and cell apoptosis.

结果不同浓度的5氟尿嘧啶处理A549细胞，随着药物浓度的增加和处理时间的延长，细胞存活率明显下降；且低浓度使细胞呈铺展状态，细胞质内空泡增多，吖啶橙染色显示酸性膜泡增多，高浓度使细胞变圆，出现凋亡状态。

The results showed that structure of root tissues became disorder and appeared void with increase of the N and P concentration; The content of N, P were increased gradually with the N and P concentration increased; activity of POD, SOD and CAT of Vallisneria spirolis were enhanced gradually with increasing the N and P concentration.

研究发现，随营养程度的增加，苦草根的组织结构紊乱，出现空洞；根叶中氮、磷含量都是随营养程度的增加而增高；苦草叶组织的POD、SOD、CAT活性均随营养程度的增加而上升；随培养时间的延长苦草叶组织的POD和CAT活性呈先上升后下降的趋势，SOD活性下降。

Still have, grow in its in development process, if discover blade is shown lilac produce curly phenomenon, show excess of nitrogenous fertilizer employ, answer right now decelerate little dose or extend fertilization time; And blade is shown virescent make clear devoid nitrogenous fertilizer again, answer to increase dose appropriately.

还有，在其生长发育过程中，假如发现叶片呈淡紫色并产生卷曲现象，就说明氮肥施用过量，此时应减速少施肥量或延长施肥时间；而叶片呈淡绿色则又表明缺乏氮肥，应适当增加施肥量。

It is thus clear that besides Octoxinol and Benzalkonii Chloridum have the spermicidal and virucidal functions, the main function of the other elements is only to lubricate, make them become semisolid, clear gel and extend the periods of time in the vaginal walls.

可见，除辛苯聚醇和苯扎氯胺具有杀灭精子和病毒的功效外，其他成份的主要作用仅是润滑、使其成为半固态清晰的凝胶并延长在阴道壁的停留时间。

The amount of total phosphorus is one of the most important indexs to judge surface water.During the flood,detecting data show that the hi gh am ount of total phosphorus mainly come from phosphorus absorbed on mud,but the am ount of dissolved phosphorus is low.The amount of total phosphorus in surface wab~r declines gradually with the prolonging of static balance time.

地表水中总磷含量高低是评定水质优劣的一项重要指标，分析数据表明丰水期中总磷主要来源于泥沙中吸附的有机磷和无机磷，而溶解态磷含量较少；水样中总磷含量随着自然沉降时间的延长而逐渐降低。
