Results: The essential oil from the fresh Houttuynia Cordata Thunb possessed the highest antibacterial activity against Staph.aureus and Sarcina,and the MIC was 1/2 х 10(-3) ml/ml.

结果：鱼腥草鲜样挥发油的抑菌效果最强，对金黄色葡萄球菌、八叠球菌的MIC均为1/2×10-3ml/ml，在贮藏过程中随着时间的延长MIC逐渐增大。

Veidt and Sarna had affirmed that five or even fifteen minutes' exposure to Garuda's atmosphere wouldn't prove lethal; but at the same time the danger to Rick and the others was increasing with each moment they were kept from proper treatment.

维特和莎娜已经确认了在嘎鲁达大气中曝露5分钟甚至15分钟并不会致命；但同时对瑞克和其他人来说，危险会随着他们未接受护理时间的延长而增加。

Nanoparticles as drug carriers can solubilize poorly water-soluble drugs in their inner core, avoid being quickly taken up by the reticuloendothelial system and prolong circulation time in the blood.

纳米粒子作为药物释放载体可避免被网状内皮系统快速吞噬，延长在血液里的循环时间。

With the increase of exposure intensity and time,the Bax and Bcl2 exprseeion in spermatogenic cells in rats were gradually decreased.

随着电磁场暴露频率的升高和时间的延长，大鼠生精细胞Bax的表达明显上调，Bcl-2的表达逐渐下调。

In the testis, the expression of Ob-RL is close related to the spermatogeny cycle.

在睾丸中， Ob-RL的表达量随SD时间延长，表达量逐渐上升。

A novel polymer of Poly(diglycidyl maleate-co-stearyl methacrylate) was synthesized and its structure was characterized by ~1H NMR. Its self-assembly behavior was studied in different solvents. It was found that vesicles and tubule-liked aggregates can be obtained through self-assembly of P(DGMA-co-SMA)/THF/EtOH system. And spheral aggregates were obtained in P(DGMA-co-SMA)/THF/H_2O system while the spheral aggregates were converted into rod-liked aggregates and line-liked aggregates after aged for different time.

合成了带含环氧基侧链和十八烷基侧链的聚(马来酸二缩水甘油酯-co-甲基丙烯酸十八酯)，用~1H NMR对所得的共聚物进行了表征；研究了其在选择性溶剂中的自组装行为，发现P(DGMA-co-SMA)／THF／EtOH体系可以通过自组装形成囊泡形自组装体和支化的管状自组装体，P(DGMA-co-SMA)／THF／H_2O体系最初自组装形成球形自组装体，随着陈化时间的延长，球形自组装体逐渐融合成长条形自组装体和线形自组装体；探讨了自组装过程的机理，建立了可能的自组装过程模型。

The results showed that heat treatment had no obvious effect on main linkage way of the system. Between 500℃and 900℃, the crystal phase CaF_2 was precipitated firstly, with the rising of temperature and the prolonging of time, crystal phases such as Al_2SiO_5、Ca_2SiO_4 and Ca_3(PO_4)_2 were precipitated sequentially and the powder was changed from dispersive spheroidic to irregular strip that linked each other, and congregated to irregular mass, gradually.

热处理对体系的主体键连方式无明显影响；在500-900℃温度范围内，粉体优先析出CaF_2晶相，随着加热温度的升高及保温时间的延长，依次析出Al_2SiO_5、Ca_2SiO_4、Ca_3(PO_4)_2等晶相，粉体由分散的近球形颗粒转变成相互粘连的不规则带状，并逐渐聚合成不规则块状；固结体抗压强度逐渐增加后趋于平缓。

The margin of the white matter tract become more clearly with the increasing of the number of gradient encoding directions, especially the detail of the brain stem. But the measured FA of the centrum semiovale, genu and splenium of corpous callosum, the internal capsule, thalamus and the pons with 6, 13 and 21 diffusion gradient encoding directions showed no statically difference.

随着弥散梯度编码方向的增加，FA图质量提高，对白质纤维束细节的显示也更清楚，尤其是对脑干结构的分辨，但成像时间延长；3种不同弥散梯度编码方向的DTI扫描方案所观察到的半卵圆中心、胼胝体膝部、胼胝体压部、内囊、丘脑及桥脑的FA值不存在统计学显著性差异。

It was found that levels of IFN-γ and NO in splenocyte supernatants stimulated by PRBC or LPS from DBA/2 mice were remarkably higher than those of 1640 culture group,and they increased gradually with culture time.

结果表明以PRBC或LPS刺激后，DBA/2小鼠脾细胞上清液中IFN-γ和NO水平随培养时间的延长均有不同程度的提高，但BALB/c小鼠48h培养组的IFN-γ和NO水平仅比24h培养组略有升高。

Lift along with reaction temperature and the extension of time, in synthesizing child, miscellaneous photograph decreases, steatitic brilliant granuality increases Mg-Al water gradually.

随反应温度升高和时间的延长，合成产物中杂相减少，Mg-Al水滑石晶粒度逐渐增大。
