查询词典 molecules

I remember seeing a television program about scientists using computer graphics and sometimes virtual reality to visualise complex molecules.

我想起看过的一个电视节目，科学家们使用计算机画图，或者有时使用图形构象来使复杂分子图形化

A new type of chemical analysis has spotted the telltale signs of water molecules inside tiny beads of volcanic glass brought to Earth decades ago by the Apollo astronauts.

他们利用一种新的化学分析法，在小块火山玻璃珠里发现了水分子的明确迹象。玻璃珠是由"阿波罗"号宇航员于几十年前带回地球的。

The experimental results show that Mn2O3 was main active species and addition of Zr further activated methane molecules to improve methane conversion; C2 selectivity was improved by adding W and P, and suppressed deep oxidation property of SiO2; W–O in catalyst surface was not active species.

通过选取五组该催化剂对其进行XRD、XPS、FT-IR以及SEM表征，表明Mn2O3和Na2Zr(PO4)2是多组分甲烷氧化偶联催化剂的活性组分，且Mn2O3起主要作用，Zr的加入进一步活化了甲烷分子，提高了甲烷的转化率，W和P的加入改善了C2烃的选择性，抑制了SiO2的深度氧化特性；W–O物种不是催化活性物种。

The water-induced stress is formed by two mechanism: electrostatic dipole interactions between the adsorbed water molecules and hydration of silica.

水致应力源于：水分子偶极矩相互排斥的物理机制和水合作用的化学机制。

The fact that spin-label molecules exchange between free water and hydrophobic region was proved by ESR, the arrangement of surfactant chains become loose in the process of hydration and water can penetrate into hydrophobic region of reverse microemulsion.

ESR结果也说明探针分子在反相微乳液的自由水及疏水环境间交换，在水化过程中表面活性剂链的排列较为疏松，且水分子渗透到反相微乳液的疏水区域。

Compound 4 is a lanthanide-polyoxometalate wavelike chain, with racemic proline molecules situated in the framework via hydrogen bonds.

化合物5显示B型Anderson多酸与稀土-甘氨酸配合物形成的3D超分子孔道结构。

It means that in this type of binding one HSA molecule can bind many drug molecules but the interaction is very weak.

低亲和力结合中心有较大的结合容量，这就意味着对于这种类型的结合来说一个HSA分子可以结合较多的药物分子，但是它们之间的相互作用很弱。

At the same time, weak interaction in molecules is closed correlated to many chemical and physical phenomenon, even it consists in biology universally.

同时，许多化学和物理的现象与分子间的弱相互作用相关，尤其是在生物体系中的弱相互作用更是普遍存在。

With that information and some high-speed silicon-age machinery--they can build new molecules that home in on their targets like well-aimed arrows.

借助这一信息，加上高速硅时代的机器，科学家可以建造新分子，这些分子像准确命中的箭一样。

They're just well-formed molecules.

他们只不过是好的外形组合。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
