推测

Apparently they were even capable of migrating between stars, presumably while in some kind of larval form.

他们很明显地甚至能在星际间迁移，推测是在一种幼虫状态。

Gravid An. sinensis demonstrated significant negative taxis towards bacteria A4 and Aeromonas sp., as well as slight taxis to Enterobacter sp., implying that the three bacteria were not the dietary preference for An. sinensis. However, in light of the possibility of their stable colonization into mosquito's guts, these strains may serve as the host cells of larvicide genes and transgenic anopheline antimalarial genes.

中华按蚊产卵时对A4菌和气单胞菌具有明显的负趋性，而对肠杆菌仅具有微弱的趋向性，推测这3种细菌可能不是中华按蚊食物的优先选择，但具有在蚊中肠内较为稳定存活的可能性，因此更适合于作为蚊幼生物杀虫基因的寄主细胞和仿转基因按蚊抗疟基因的寄主细胞被应用。

We argue that the hemispheric asymmetry of iron content may underlie that of the dopaminergic system and may be related to motor lateralization in humans.

我们推测这种不对称性也许反映了左右大脑半球在多巴胺代谢中对铁的不同需求，并和人类的运动偏侧化分布有关。

Chapter 4 describes the synthesis, structural characterization and properties of anovel organic-inorganic hybrid compound, F〓〓BEDT-TTF =bis(ethylenedithiotetrathiafulvalene, which has been synthesized through thereaction of the pre-intercalate Fe〓PS〓〓(phen = 1.10-phenanthroline) with〓 Compared with the pristine FePS〓, the lattice spacing isexpanded by about 4.0〓, indicating that the molecular ring plane of BEDT-TTF isarranged parallel to the layer of the host.

通过红外光谱推测客体BEDT-TTF在层间以中性状态存在。X-线光电子能谱揭示在夹层化合物Fe〓PS〓〓中磷原子和硫原子在硫代亚磷酸根负离子簇中各存在两种化合价态，其中一种价态与纯主体或预夹层化合物〓〓中的磷原子和硫原子价态一致，而另一种价态却比纯主体FePS〓或预夹层化合物Fe〓中的磷原子和硫原子价态高。

2It is presumed according to the distribution patterns of Aletris L. and itsgenetically close genera that Aletris L. probably originated in Laurasia not later than the early tertiary.

2根据粉条儿菜属及其近缘属的分布格局推测，该属可能在不晚于第三纪早期，起源于古北大陆。

The favorable regions for DNA cleavage were observed to be pH 3.6-5.6 and pH 9.0-10, suggesting that the species responsible for DNA cleavage are different in different pH regionsOur results do not support a widely accepted conclusion that the copper-bound or free hydroxyl radicals provided by CuZnSOD with its end product hydrogen peroxide lead to release of copper from its host, the Fenton reaction between the free copper and the hydrogen peroxide being responsible for the aberrant copper-mediated oxidation chemistry in CuZnSOD.

目前广泛接受的一个推测机理是CuZnSOD与H_2O_2反应生成羟自由基损伤酶自身导致Cu释放，而释放出的游离Cu进一步与H_2O_2发生Fenton反应导致了异常催化氧化反应的发生。

The liqase was positively controlled by HAI and AI-2 to some extent. The lecithinase was negatively controlled by HAI-1, and the hemolysin was negatively controlled by both HAI-1 and AI-2. Special primers of luxS gene were designed from the luxS gene sequence of V. harveyi obtained from the GenBank, and the gene was amplified from a pathogenic strain V. harveyi VIB645 by PCR. The luxS gene was cloned to a cloning vector pUC, and was sequenced. It was found that the open reading frame is 519 bp. The similarity of the luxS gene from V. harveyi VIB645 to the published sequence of V. harveyi strain in GenBank was only 90%.

从GenBank中获取哈维氏弧菌中编码AI-2合成酶的luxS基因序列设计一对特异性引物从哈维氏弧菌VIB645中PCR扩增luxS基因，将luxS基因克隆于pUC载体并测序，发现其与GenBank中已发表的哈维氏弧菌的luxS基因序列相似性为90%，证明LuxS/AI-2系统在哈维氏弧菌不同的菌株中的具有一定的特异性，推测LuxS/AI-2系统可能与哈维氏弧菌的致病性或发光现象有关。

The results showed that there were two kinds of grains in the cells,one was large and had low electron density,Gl for short,while the other was small and had high electron density,Gh for short.The latter ones had a circle around it which can be seen through the microscope.During the aroma releasing period,the shape of the two grains changed distinctly,which led to the inference that Gl was the leucoplast,the store-room of aroma precursors or energe substances,and that the Gh was probably the lysosome which is related to the enzyme system?s aroma producing.The circle around Gh is the formed fragrant constituents and the aroma forming is the result of the interaction of Gh and Gl .

结果发现，茉莉花瓣细胞中存在电子密度较低、体积较大的颗粒和电子密度较高、体积较小的颗粒（分别简称为Gl和Gh颗粒），并在Gh颗粒周围存在清晰的晕圈；在茉莉花释香过程中，两种颗粒在形态上均发生明显的变化，推测Gl颗粒可能是白色体，是茉莉花香气前体物或能量物质的贮存器，Gh颗粒可能为溶酶体，与香气形成的酶系统有关，Gh颗粒周围存在的晕圈可能是香气物质，香气物质的形成是Gl和Gh颗粒相互作用的结果。

Its origins are uncertain, but it is speculated that it represents either a rolled up herdsman's shelter or a papyrus life-preserver used by ancient egyptian boaters.

它的由来不确定，但据推测它要么表现了用金箔包裹的牧人的庇护所要么生命保存者用于古埃及乘船者的纸草。

There are a numbers of the osmiophilic substance in the plastids of secretory cell in the secretory phase in the peltate hairs and the place of synthesis of lipoid substance can be considered to be in the plastids.

观察发现，在盾状腺毛处于分泌期的分泌细胞的质体中存在大量的嗜锇物质，推测质体可能是脂类物质的最初合成场所。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
