查询词典 molecules

For instance, they are red, they have grown on a tree, they are composed of organic molecules, and they taste bad (that is the sorry truth about Red Delicious apples, in spite of their self-congratulatory name).

例如，它们是红色的，长在树上，由一些化学组织构成，尝起来如何如何。

Though the result was not so good, a general understanding of the problems lying in the manufacture process of the device was gotten.We found the symmetry was destroyed or decreased in the crystal structure of symmetrical star-shaped molecules, such as tetra(4-cyanophenoxymethyl-methane, tetra(N-pyrrolemethyl)methane, and a center of charility was self-formed.

本文发现，原本高度对称的星状分子，在晶体结构中，分子对称性破坏或降低，表现为手性分子；以四(4-氰基苯氧基甲基)甲烷为例，从分子间氢键作用的角度，解释了该现象形成的原因。

We found the symmetry was destroyed or decreased in the crystal structure of symmetrical star-shaped molecules, such as tetra (4-cyanophenoxy methyl -methane, tetra (N-pyrrolemethyl) methane, and a center of charility was self-formed. The phenomena was discussed by analyzing the intermolecular hydrogen-bonding interactions of tetra (4-cyanophenoxy methyl -methane.

本文发现，原本高度对称的星状分子，在晶体结构中，分子对称性破坏或降低，表现为手性分子；以四（4-氰基苯氧基甲基）甲烷为例，从分子间氢键作用的角度，解释了该现象形成的原因。

Replicas of DNA are made when the double helix unwinds as a result of helicase enzyme action and the separated strands serve as templates along which complementary nucleotides are assembled through the action of the enzyme DNA polymerase. The result of the two new molecules of DNA each containing one strand of the original molecule, and the process is termed semiconservative replication.

DNA 的复制在解旋酶解开 DNA 链时开始，解开的链作为模板 DNA 聚合酶的作用下结合相对应的核苷酸，最终形成了两条新的 DNA 的链，每一条的链含有一条链原来的 DNA 单链，因此又叫做半保留复制。

Semiconservative replication :The two strands of DNA double helix are separated, each strand serves as a template for the synthesis of a new complementary strand, producing two daughter molecules. Each daughter molecule has one parental strand and one newly synthesized strand.

半保留复制： DNA 生物合成时，母链 DNA 解开为两股单链，每股单链分别作为模板，以 dNTP(dATP 、 dGTP 、 dCTP 、 dTTP)为原料，按照碱基配对(A － T 、 G － C)规律与模板上的碱基配对，经依赖 DNA 的 DNA 聚合酶催化，合成一条与模板互补的新链，新形成的两个子代 DNA 与亲代 DNA 碱基序列一致，子代 DNA 分子中一股单链是从亲代完整地接受过来，另一股单链是新合成的，故称为半保留复制。

A compromise between the implicit and explicit models, known as discrete-continuum, cluster-continuum, semicontinuum, orsupermolecule-continuum model, is to include several solvent molecules around the solute into the QM part, but the rest bulk solvent is treated with the continuum theory.

结果表明：(1)，离散—连续组合模型既在从头算水平考虑了溶质分子和第一溶剂化层中溶剂分子间的短程作用，又包含了溶剂效应的长程静电作用；既包括了量子力学的精确性，又利用了连续场的高效性。

The complex, semifluid, translucent substance that constitutes the living matter of plant and animal cells and manifests the essential life functions of a cell. Composed of proteins, fats, and other molecules suspended in water, it includes the nucleus and cytoplasm.

原生质一种复杂的，半流动的，半透明的物质，是植物和动物细胞中的活性成分，是细胞生命现象的主要表现由蛋白质，脂肪和其它悬浮在水中的分子构成，包括细胞核和细胞质

Diffusion of molecules through a semipermeable membrane from a place of higher concentration to a place of lower concentration until the concentration on both sides is equal.

液体通过一个半透膜进行的扩散，直到膜两边液体的浓度相同为止。

Separations in semipermeable membrane systems is based on forcing some of the molecules in the system through the membrane while retaining others on the feed side.

半渗透膜的分离体系是基于迫使某些分子通过半透膜而使其它的分子保留在进料一侧。

They use the carbon thus sequestered to make molecules like cellulose, and thus more tree.

树木将大气中的碳元素固定成为像纤维素一类的碳分子化合物，并孕育更多的树木。

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。
