When feeding with undecylenic acid by fed-batch culture, there was a lag time when microorganism using undecylenic acid as a new carbon source. The molar fraction of unsaturated monomer could be achieved by 37.39% at 73 hr cultivation. We can see the property of PHA become flexible with cultivation time by the lower of Tg.

发酵槽馈加十一烯酸培养实验，产物为PHO与PHU(poly-3-hydroxy-8-noneneoate为主)所形成之混掺物，且双键所占比例随时间增加，培养第73小时可得到双键比例37.39%；随培养时间增加，玻璃转移温度(Tg， glass transition temperature)由-34.03℃下降至-42.40℃，显示PHA性质变得更加柔韧具有弹性。

Glimpsed through undraped windows as they darted from room to room, the slim figures of the children seemed to grow ever fatter until, finally, the kitchen door flew open and out burst three awesomely bundled objects that set instantly to rolling in the snow.

透过窗户，只见那家的几个孩子在几间房屋里来回跑动，瘦小的身影似乎变得越来越胖，最后，厨房门蓦地打开了，蹦出来三个包裹得圆圆滚滚的小东西，在雪地里打起滚来。

Unexplainably, Luke began to fuss.

突然间，卢克开始变得有些手忙脚乱。

The viscosity of irradiated PP/SBS was lower than that of unirradiated PP/SBS, which implied that the irradiated blends could be easily processed by injection molding.

辐照一定剂量后，由于辐射交联和裂解的进行，使PP/SBS的流变性能和结构及内耗行为发生大的变化，PP与SBS两者玻璃化转变温度间距离变小，从而改善了PP/SBS的相容性。

Joint Time-Frequency Analysis is a new-style theory in Signal-Analysis, which combines the signals' characters in time domain with those in frequency domain. For reflecting the integral character, JTFT possesses good effect in analyzing unstationary or time-changing signals.

联合时频分析方法是一种新型的信号分析理论，它结合了信号在时间域与频率域的特性，反映了信号频率随时间变化的综合特性，在分析非稳定、时变信号方面具有很好的效果。

RESULTS: The passaged MSCs exhibited uniform appearance in fusiform shape, and their growth was slowed down after 9 passages, exhibiting cytoplasm vacuolization and body enlarging.

结果：传代培养的骨髓间充质干细胞形态均一，呈梭形、纺锤形，克隆样生长，培养至9代后生长减慢，并出现胞浆空泡化、胞体变大等老化现象。

The results show that for a supersonic shear layer without reaction, a disturbance can make the shear layer become unstable, this results in one vortex or more than one vortex. The combination and seperation of vortex can intensify the mixing. But it is not easy for supersonic reacting shear layer with exotherm to become unstable with disturbance, and the effect duration is very long.

结果表明，对完全气体的超声速剪切层流动，一定的激励方式能使原先较为稳定的剪切层流动变得不稳定，产生单涡或多涡结构，发生多涡间的合并，使混合加剧；但对于存在放热现象的反应超声速剪切层流动，外加激励方式不易使流动从稳定变为不稳定，而且外加扰动的作用特征时间也较长，实际应用前景不乐观。

A strange feeling of warmth bubbled up in my throat, despite the icy rain splattering on my cheeks.

一种奇怪的暖流在喉咙间穿流，打在脸颊上的冰冷雨滴变得不再无关紧要。

It may grow and flourish in mutual maturity. It may sour in hated dependence or independence.

它可以在父子间同的成熟过程中发展深化，也会在充满怨恨的不独立或独立的过程中变坏。

It may grow and flourish in mutual maturity. It may sour in hated dependence or independence.

它可以在父子间共同的成熟过程中发展深化，也会在充满怨恨的不独立或独立的过程中变坏。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
