片断的

As RNA polymerase pushes forward along the double helix, it generates positive supercoils ahead and leaves negative supercoils behind.

11.19 转录可能能导致在RNA聚合酶前的DNA片断缠绕更紧密，在其后的变得缠绕的不那么紧密。

It would also help to obtain integrity trajectories of saltating sand grains by extending bitty saltating trajectories grained from wind tunnel experiment in order to understand deep sand grain saltating motion.

这项研究为跃移沙粒运动参数分布函数研究提供了一条新思路，有助于将风洞实验获得的沙粒跃移运动的片断轨迹拓展，进而获得沙粒跃移运动的整个轨迹，以便深入理解沙粒跃移运动。

A quarter of employees watch or listen to streaming media at least once a week from work, and 18 percent have downloaded and stored nonwork music, photos and video clips, according to a telephone-based survey sponsored by Websense Inc., which makes software that helps companies filter and monitor Internet use.

在一周上班时间中，由1/4的员工至少看过或听过网上媒体，18％的人下载和存储过非工作相关的音乐，图片和视频片断。

IPad's battery life great, Mossberg found it to be even longer than Apple's ten-hour claim He played movies, TV

iPad的电池续航能力很出色，Mossberg的测试结果比苹果公布的10小时续航时间还长一些，在循环播放视频、电视节目以及其他片断

It is possible to preparing neutralizing MAb which target to active region of Stx2 by synthetical B cell epitope peptides. At present, the crystal structure of the compound of Stx2 and its ligand adenines has been resolved, and the active site of Stx2 is definite, which is the seventy-seventh amino acids, Ganimalon, of Stx2 A1 fragment.

Stx2通过B亚基与受体Gb3结合后，进入细胞，在弗林蛋白酶(一种钙敏感的丝氨酸蛋白酶)作用下A亚基被裂解为A1和A2两个片段，A1片断经内质网进入细胞质暴露毒性活性位点―A1片段发挥N-糖苷酶活性，导致真核细胞蛋白质合成的终止，最终导致细胞的死亡。

A typical area of habitat fragmentation in the Thousand-Island Lake, Zhejiang Province, was selected as subject to study effects of habitat variation as a result of island forming, on arbuscular mycorrhizae infection rate and its correlation with phosphatase activity in the rhizosphere of Castanopsis sclerophylla.

以浙江千岛湖典型生境片断化区域苦槠为材料，研究了水库形成后岛屿化导致的群落生境差异对苦槠AM侵染率的影响以及AM侵染率与根际土壤磷酸酶活性的相关性。

The paper designs a flow of work, in which the user reads symbolic library XML document from distributed symbolic library, manages these symbols by visualization management tool, saves all classes of symbols XML document fragment and transforms into SLD document, realizes interactive mapping by dint of integrated application between OGC SLD and OGC WMS.

设计了由从分布式符号库读取符号库XML文档并以利用可视化管理工具进行符号的管理，存储为各种符号XML文档片断转换为SLD文档，通过OGC SLD与OGC WMS的综合应用于交互制图的工作流程。

It was a patchwork of life as nightingales on gossamer song as fine as needlepoint threaded each piece together.

这些感受就像一些生命的片断——被精细的针脚缝缀起来的碎布片——那样非常美好。

Some developments of new drugs are derived from the splicing, disconnection and combination of present active molecular structures or substructures. Usually, this kind of work is accomplished in chemists'mind.

一些新药的开发是通过对已有的活性分子或者结构片断进行拆、拼、组合得到的，这种工作往往依靠化学家的大脑完成。

Fragments of a Rilke poem, around the ancient tower.

是里尔克的诗的片断我围着古老的灯塔。。。。。。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
