定向

As the numble of people taking part in was not very large and people felt a little tired after a long time's cross-country race,we only selected two or three games.

由于参与人数不是很多，并且大家在一个长时间的定向越野后有些疲劳，原定的团队游戏就只挑了两三个进行，不过大家玩的还是比较开心。

Recent data suggested that Notch receptors and their membrane-bound ligands Delta and Serrate were involved in both patterning and cell fate determination during odontogenesis.

越来越多的证据表明：Notch途径参与了牙齿发育的各个过程，包括牙齿早期发育细胞的增殖、分化过程，决定细胞的定向分化方向，决定成牙本质细胞与成釉细胞的终末分化命运，并且参与牙齿炎症损伤后修复过程，与第三期牙本质的形成有关。

To accept the oldness is an inevitable chalange for us,we should not treat it as an aberrable crisis.

这个家伙很懒，什么也没留下。。。。。。汽车行业笔译就业定向班，100%就业

But the course of my life, when I look back, is as orderless as a trickle of water that is diverted and guided by every pebble and crevice and grass-root it encounters.

但当回首往昔，我发现自己的生命历程就像溪流之蜿蜒漫无定向，触石砄草根则避而改道，遇岩缝土隙则顺而流之。

In this study, the structure sequences of Shiga toxin 2B(stx2B) and Shiga toxin 1B(stx1B) were respectively amplified from EHEC O157:H7 by PCR. stx2B-L-stx1B fusion gene was constructed by a 12 bp linker ligating these two fragments. After digested with restriction endonuclease Nco Ⅰ and EcoR Ⅰ, the fusion gene was orientally inserted into expression vector pET28a.

利用PCR方法，从肠出血性大肠杆菌O157：H7的基因组DNA中，分别扩增出Stx1B和Stx2B亚基的结构基因片段，然后再通过PCR将这2个片段连接起来，并定向克隆到表达质粒pET28a的NcoⅠ和EcoRⅠ位点之间，构建了重组表达质粒pMB1。

The results indicate that only tungsten oxide grains are formed without sodium sulfate additions, while tungsten oxide whiskers with 0.20.3 μm in diameter and aspect ratio of 5-50 or tungsten oxide nanowires with 1030 nm in diameter and aspect ratio of 50200 are synthesized by some sodium sulfate additions on conditions at 180 ℃ for 1236 h. The phase composition of tungsten oxide whiskers is hexagonal tungsten trioxide. The whiskers/nanowires grow oriently through 〈200〉,〈002〉,〈202〉and〈100〉.

结果表明：未添加硫酸钠时，在180 ℃水热反应12~36 h只能得到氧化钨颗粒粉末，而添加适量硫化钠后，可制备出直径为0.2~0.3 μm、长径比为5~50的氧化钨晶须和直径为10~30 nm、长径比为50~200的氧化钨纳米线；氧化钨纳米线晶体结构良好，物相为六方晶系WO3；微/纳米氧化钨晶须/线主要沿〈200〉，〈002〉，〈202〉和〈100〉方向定向生长。

Orthogenic life advanced in a direct line, from organism A through the alphabet of life to organism Z.

定向进化的生物沿着一条直线发展，从最早的生物A，通过生命的字母表，一直演化成最后的生物Z。

OBJECTIVE: To investigate the proliferation and osteoblastic differentiation of adipose-derived stem cells induced by calcitonin gene-related peptide in vitro.

目的：探讨降钙素基因相关肽在体外定向诱导脂肪干细胞向成骨细胞增殖分化的可行性。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
