打靶

Backscattered light energy is 7.8% of laser energy when laser is focused on Au disk target; when laser beam is smoothed, it is 6.2%. The comparison shows that laser smoothing can restrain backscattered light efficiency.

在聚焦条件下背向散射能量约占打靶激光能量的7.8％；在束匀滑条件下背向散射能量份额下降到6.2％左右，证明了束匀滑可有效抑制背向散射。

And now let's do some target practice!

现在，让我来练习一下打靶！

That said, it wasn't all wild chases and carefree target practice.

有人说，这款游戏可不是纯粹的野蛮追击和自由打靶。

Fortunately, there are two bullet casings, know who took part in target practice.

还好，有两个子弹壳，知道自己曾经参加过打靶。

Large high-power solid-state laser facilities have a very high requirement for the total positioning error budget (0μm in general), so it is a very important to improve the stability of structure design.

大型高功率固体激光装置通常要求总的打靶精度为几十微米，这对结构的稳定性设计提出了很高的要求。

Susan Sodoma and her husband, Peter, admire FNH USA's new Special Operations Forces Combat Assault Rifle. Sodoma, who is the 2001 Utah women's trapshooting state champion, said,"It's just precision. It's an awesome gun." The couple, who both work for Browning, admit they love all guns.

2001年犹他州飞盘打靶冠军Susan Sodoma和他的丈夫正在检视一把FN公司设计制造的FN-SCAR自动步枪，此二位现就职于勃朗宁公司，酷爱各式火器。

Through such a study, it is also shown that when the time delay is long enough such that the stability switches of the equilibrium of system halt, the bifurcation branches originated from the critical time delays cannot be surely stable or unstable in the whole solution space, that is, their stability depends on cases.

利用打靶法的数值结果说明了当系统平衡点不再发生稳定性切换时，源自这些临界时滞处的解支的稳定性在整个解空间的稳定性具有不可判定性，这也说明由多尺度法所得高阶近似判定的解支的稳定性事实上只表示解支在局部中心流形上的稳定性，而非在整个解空间中的稳定性。

Firstly, the recombinant engineering technology related vaccine preparation was set up, including: 1. the gene knock-out based on linear DNA target molecular in vivo; 2. the selection and counterselection technology of exogenous gene knock in definite site on chromosome; 3. the Gap-repair clone technology in vivo; 4. the recombination technology of single-chain DNA and the overlapping primer; 5. Set up the new selection and counterselection technology of neo-E.

本研究首先建立与疫苗制备相关的重组工程技术包括：①基于线型DNA打靶分子的大肠杆菌体内基因剔除技术，②选择与反选择外源基因定位敲入染色体上特定位点技术，③Gap-repair体内克隆技术，④单链DNA重组技术和重叠引物介导的DNA重组技术，⑤建立&抗生素-酶切位点&选择反选择技术新技术。

According to the successful experiences on transgenic animal production and animal cloning, gene targeting could be utilized in many fields including theory and application research on genomic modification (such as site-specific gene repair, genetic defect therapy, gene knockout, infaust gene modification, even the site-specific integration), improving expression level of specific gene in animal mammary gland bioreactors, and promoting the industrialization of transgenic animal production.

结合现有转基因动物和动物克隆技术方面的经验，利用基因打靶技术，开展动物基因组修饰的理论和应用研究，即可定点进行基因修复、治疗遗传缺陷、基因敲除失活不利基因，还可最终解决动物乳腺反应器存在的随机整合率高而表达率较低的问题，实现定点整合及乳腺特异表达，为转基因动物的产业化生产创造条件，代表了当今动物遗传学发展的主流方向。

The main requirement at that stage will be extremely safe and effective gene therapy, both of the insertional variety (putting new genes into chromosomes) and the replacement ("gene targeting") variety.

在这个阶段的主要要求是极其安全和有效的基因疗法，不管是插入类，还是取代类（&基因打靶&，改变已有的序列）。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
