But when one member of the research team, Jennifer Stephens, knocked out a single gene in the trypanosome known to make fatty acids in other organisms, there was no change in the parasite's ability to make myristate.

但是该研究团队的成员Jennifer Stephens敲除了在锥虫中和其他物种中已知的合成脂肪酸途径中的单个基因时，寄生虫合成十四酸脂的能力没有改变。

Surprised, the researchers then examined the trypanosome genome more carefully and discovered enzymes that in other organisms are known to increase the size of a fatty acid molecule - dubbed elongases, for making fatty acids longer - but never have been shown to actually make a new fatty acid molecule.

奇怪的是，这是研究人员更仔细地检查了锥虫的基因组，发现在其他物种中作为抑止能增加脂肪酸长度的分子（同步复制延伸酶，目的是合成更长的脂肪酸，但是从来没有发现它真正能合成脂肪酸分子）。

By the interaction of ethyl acetate and water class solution, The nano silica was synthesized on fused silica capillary tubular inner surface, its morphology and change trend of surface area pore volume and pore size under different reaction condition were investigated.

本文采用化学方法对四种工艺条件下合成的脲醛树脂进行相关分子含量测定，结合实验结果和合成工艺作了结构分析，并对比分析了衰减全反射红外光谱图。

The authors believe that the diversification of rock zonation and lithology of these high pressure rocks can be attributed to the metasomatism that took place between deep melt and ultrabasic rocks in the subduction zone, and thus propose a hypothesis of subduction melt metasomatism to explain jadeite formation.

笔者认为俯冲带中形成的深部熔体与超基性岩之间的交代变质是导致岩石分带和岩性多样化的根本原因，提出了俯冲带熔体交代成因说，认为俯冲带、深部流体和超基性岩体是形成翡翠及其过渡品种的3个必要条件，并因此指出在人工合成过程中引入流体相很可能是降低实验条件的苛刻程度、从而合成出真正具有商业意义的翡翠的途径。

This algorithm constructs the combined envelope by selecting the larger elements in each range bin of the two unaligned echoes, and a new principle based on minimum sum is utilized to measure the alignment.

该算法选取待对准两回波中各距离单元中的较大值构成合成包络，并依据合成包络的和是否达到最小这一新准则来衡量回波是否对准。

More importantly, this method can synthesize a facial image with mouth opened and teeth showed from an unexpressive image with closed mouth. It outperforms other existing methods for facial expression synthesizing.

更为重要的是，该方法能从闭着嘴的中性表情人脸图像合成出具有张开嘴露出牙齿效果的人脸表情图像，克服了当前大多数人脸表情合成方法不能实现这一效果的不足。

The synthesis of DEC by vapor phase directoxidative carbonylation of ethanol was evaluated as "green technology" route withmild condition, unharmful byproduct and high atomic economy.

乙醇气相直接氧化羰基合成DEC以CO，O_2和乙醇为原料，原子经济性高，原料易得，副产无害，是一条最具发展潜力的非光气法绿色合成工艺路线。

The descriptions of 300V and 8100 X-lite have only uninformative words about "100% Synthetic - Double Ester Technology" or "100% Synthetic - Ester Based", but how much esters contained in motor oils exactly?

在300V和8100 X-lite的包装说明上有著不太资讯化的字眼有关100%合成油-双酯科技或者100%合成油-酯类基础油，但有多少比例的酯类在这机油内呢？

Using generalized Grover's algorithm of multiple marked states, and by designing a proper unitary operator, we propose a scheme for synthesizing quantum superpositions, and realize the scheme to synthesize NMR analogues of Einstein-Podolsky-Rosen states (pseudo-EPR states).

利用多标记态情况的广义Grover算法，我们通过选择适当的幺正变换，提出了合成量子叠加态的方案，并在实验上合成了赝EPR态。

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
