时间很短的

Nucleonics' researchers have shown the ability of shRNA produced in this way to silence genes, including Hepatitis B, Hepatitis C, and HIV, in relevant cell lines for extended periods of time.

nucleonics的研究已显示出他们有能力短发夹这种方式产生的基因沉默，其中包括乙型肝炎，丙型肝炎，艾滋病毒，在相关细胞株很长时间。

But activation at left medial orbitofrontal lobe, right amygdala, bilateral hippocampi and anterior cingulate gyri was different in the 2 tasks(P.01). Conclusions With isoamyl acetate as odorant, modified OEP-98C olfactometer, short TE and event-related design, olfaction fMR imaging can depict cortex activation at primary and secondary olfactory cortex.

结论醋酸异戊酯作为嗅觉刺激剂，用改进后的适应MR环境的OEP-98C型嗅觉诱发电位仪，选择较短TE时间，事件相关设计的嗅觉fMRI成像，可以很好地显示初级和次级嗅觉皮层的激活。

"Because the molecules in liquids are so densely packed together , the average time between collision s is a picosecond or less ."

由于液体中的分子很密地积聚在一起，所以，两次碰撞之间的平均时间间隔只有一微微秒或者更短些。

It's funny how you become emphasis in little detail, especially when you feel little things unsecured that detail having right Chinese containers and right take-out coffee cup which was just not like polystyrene cup of today.

前面说了这么多，教父其实已经很有烂片的潜力了：拍摄时间短、剧组不配合、制片人不支持。但教父却成功了，我想这应该归功于科波拉严谨、认真的态度。

Because the working relationship, you can give me the time is less, so sometimes really feel very sorry, but as long as you free after a short letter can be prickling i aggrieved heart, you know?

因为工作的关系，你能给我的时间是少之又少，所以有时候真的觉得很难过，但只要你忙完后的一条短信就可以安抚我委屈的心了，你知道吗？

The seasonal division and their change in various Sichuan areas is discussed using the daily mean temperature data of Sichuan 135 stations and the seasonal division method by Zeng Qingcun et al. It is shown that:(1) Between 1961-2004 each seasonal length is different, summer and winter are longer than spring and autumn, and difference of the seasonal division in different areas is mainly shown by the time scale of spring and autumn.

利用四川地区135个台站的逐日温度资料和曾庆存等提出的季节划分方法，讨论了四川各区域的气候季节划分和季节变化，结果农明：(1)1961~2004年期间，四川地区季节的四季分配很不均匀，冬夏季偏长，春秋季节偏短；并且四川不同区域间的季节划分差异主要表现在春秋两季的时间长度上。

The rates of apoptotic granulosa cells in all kinds of follicles in immature gilts were ashigh as atretic follicles;it decreased significantly after injection of PMSG,but it was higherand lasted shorter than that of mature pig.

性未成熟仔母猪卵巢中各类卵泡颗粒细胞凋亡比例很高，接近闭锁卵泡的凋亡比例；注射PMSG后则各类卵泡颗粒细胞凋亡比例显著下降，但高于性成熟母猪注射PMSG后的凋亡比例，并且维持的时间也较短。

Mid-Pleistocene microtektites were recovered from the interval between core depth 386.12 and 386.38 mcd but concentrated in a 3 cm-thick layer between ...

研究结果表明，中更新世撞击事件对环境的影响很可能只是小幅度和短时间的，尽管引起了南海表层海水温度约 2°C的下降及其相应的δ1 8O的加重、浮游有孔虫冷水种含量的上升和暖水种含量的减少，但没有造成海水稳定同位素重大偏移和全球气候的灾难性影响，也没有引起浮游有孔虫在生物演化上的变化。

A Dense scale on the2O3(Cr/Y=4/1) coated specimen;2O3(Al/Y=3.6/1) coated specimen; Oxide nodules formed at the corner on the specimen coated with2O3(Cr/Y=2/1) deposited for 15 s; Locally spalled scale on the same specimen as in; The trace of cracks in the deposited oxide film on the scale formed on the specimen coated with2O3 (Cr/Y=2/1) deposited for 60 s; Showing the similar trace on the same specimen as in b

沉积复合OTFC试样的氧化层形貌有如下特征：(1)氧化层绝大部分致密、完整、与基体附着良好，晶粒细小（图7a，7b）；(2)在短时间(15s)沉积2O3 OTFC试样的局部表面出现了不均匀氧化（图7c，7d），但只是在沉积Cr/Y=4/1膜试样的局部表面产生了类似无涂层Fe25Cr上剥落的厚膜（图7d）；(3)沉积2O3(Cr/Y=2/1) 60s（图7e）与15s（图7c）的结果不同，前者整个试样表面氧化产物颗粒细小，无粗大氧化物颗粒形成；(4)沉积2O3(Cr/Y=2/1) 60s和2O3(Al/Y=3.6/1)薄膜的试样由于氧化增重非常少，氧化层很薄，刻印着涂层中局部出现的裂纹（图7e，7f），这种印迹的保留可能反映着传质机制的改变，即新氧化物由在外表面形成转变为在外表面以下形成。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
