查询词典 molecule

It was believed that the chief production problem was ridding the dextran of the small molecule, to reduce the rate of excretion.

人们认为，生产的主要问题是消除小分子的葡聚糖以减少排泄率。

They had suppressed the cathodic process of carbon steel electrode. Their inhibition performance was also related with their molecule stereo conformation and electron configuration. Four of bis-(1, 1'-benzotriazoly)-α,β-diamide compounds linked via-CO 〓CO-chain were synthesized and certified by IR and 〓H-NMR. The minimum energy conformations of these compounds were obtained by MM2 forcefield program. The two benzotriazole moiety in BBT1 was more planar than in other compounds. This was beneficial in increasing the inhibition effects of BBT1. In 0.5M H〓SO〓 solution, BBT1 suppressed anodic corrosion reaction. In 3%NaCl solution, BBT1 suppressed both cathodic and anodic corrosion reactions. 1- [ (1'-imidazolly)-methyl] benzotriazole was synthesized by Mannich reaction.

合成了四个通过-CO〓CO-连接的双（1，1'-苯并三唑）-α，ω-二酰胺化合物，采用MM2分子力学程序优化了它们的分子结构，双（1，1'-苯并三唑）-α，ω-二酰胺化合物的缓蚀作用与其分子内两个苯并三唑单元的空间取向有关系，良好的平面性有利于苯并三唑二聚体的吸附和缓蚀作用，苯并三唑二聚体BBT1分子内两个苯并三唑单元近似平行，所以显示出较好的缓蚀效果。0.5M硫酸中BBT1主要抑制铜的阳极溶解的电化学反应；3％NaCl溶液中，BBT1对铜的阳极溶解和氧的阴极还原过程均有抑制作用，相比较而言对阴极过程的抑制作用更大一些。

So research symmetrical diatomic molecule have a significance.

所以研究对称的双原子分子的谐波产生有着重要的意义。

Nitric oxide is the only diatomic messenger molecule that have ever been discovered.

一氧化氮是已发现的唯一一个双原子生物自由基信使分子。

For example, for diatomic molecule the two molecular orbitals are combined by two atomic orbitals.

以双原子分子为例，两个原子轨道可以组成两个分子轨道。

Any heteronuclear diatomic molecule must have a dipole moment since its two ends are different.

任何异核双原子分子必然具有偶极矩，因为它的两端是不同的。

Figure 14.5 and 14.6 show this division for a homonuclear and a heteronuclear diatomic molecule.

图14.5和14.6示出同核和异核双原子分子的这种分区。

Key words: atomic and molecular physics; molecular alignment; femtosecond laser; diatomic molecule; numerical calculation

The ratio of the symmetrical diatomic molecule generates more than the atomic's because of charge resonance in theory.

对称双原子分子由于电荷共振，理论上比原子有更的谐波产生率。

These results supply necessary data for the studies which need high-lying vibrational energies and dissociation energies of diatomic alkali-metal molecule.

这些结果为需要碱金属双原子分子精确振动能谱和离解能的科学研究提供了重要数据。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
