The experiment results showed that, the MnO_2 particles scattered uniformally after milled for 6h, the average diameter was 300nm, which loaded on the surface of fiber in flat successfully. The removal efficiencies to HCHO of MnO_2 milled for 6h was up to 94.07% after 72h, the removal efficiencies increased with the content of MnO_2 loaded, its increased after treated with DMF, or so was 7%.

实验结果表明，研磨6h的MnO_2粉末分散均匀，平均粒径可达300nm，以平铺的形式均匀地负载于纤维上，效果比较理想；随着吸附时间的延长，研磨6h的MnO_2粉末反应72h对甲醛的去除率达94.07％；活性炭／腈氯纶负载MnO_2纤维对甲醛的去除率比未负载的明显提高；随着纳米MnO_2负载量的增大，甲醛的去除率变大，用DMF处理后的纤维对甲醛的去除率有所提高，大约提高7％。

The results showed that degradation rates of individual and total DDT in sterilized and unsterilized soils as well as unsterilized soils added different dose of laccase increased rapidly with treatment time till 15 days and generally kept steadiness till 25 days.

结果表明，在土壤灭菌与否和不同施用剂量条件下，漆酶对DDT各组分及DDTs的降解率均随着时间的延长而不断提高，且在第15天之前提高迅速，到第15天之后至第25天基本上处于稳定状态。

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。

Replacement of a ureteric catheter this shall be considered an extension of the continuous use of the device.

然而，一个器械被停止使用后，立即被一个同样的或等同的器械所代替，这样被认为是一种持续使用时间的延长。

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。

Ts , as taxe sur la valeur ajoutée was first to introduce VAT with effect from 10 April 1954 for large businesses, and extended over time to all business sectors.

ts ，因为税河畔拉valeur ajoutée是第一个引入增值税，由4月10日 1954年对大企业，并延长一段时间内的所有业务部门。

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。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.
