Result The three strains all produced the AHL signal molecules; the strains FML05-land FML05-2 produced two types of AHLs at least and the N-3-oxo-octanoyl-homoserine lactone was the predominant signal molecules. The production of siderophore and proteinase in FML05-2 were reduced by co-incubation with AHL degrader strain.

结果］3株菌均产生AHLs信号分子；菌株FML05-1、FML05-2至少产生两种AHLs分子，二者所产生的主要信号分子是N-3-氧代－辛酰基－高丝氨酸内酯(N-3-oxo-C8-HSL)；FML05-2与降解AHLs的菌株共同培养，发现嗜铁素的产量与蛋白酶活性明显下降。

Basically, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2) and that energy will be released in the process.

一个水分子由2个氢原子和1个氧原子组成。然而，我们不能简单的将2个氢原子和1个氧原子结合起来。实际上制取水的反应稍微有点复杂：2H2 + O2 = 2H2O + Energy。

The recognition capability and adsorption rate of MIP can be significantly enhanced by selective modification.Separation factor could be increased from 1.60 to 3.06 after modification when naringenin was chosen as competitive molecules, and the time needed for adsorption equilibrium could be reduced from 100 min to 60 min.Within a certain range, increasing template molecule concentration or diazomethane dosage, or adopting solvent which had weaker hydrogen bond action with template molecules could all improve the modification effect.

结果表明，选择性修饰能明显提高MIP的识别能力与吸附速度，以柚皮素为竞争分子，分离因子可从修饰前的1.60提高到修饰后的3.06，吸附平衡时间从修饰前的100 min降低至修饰后的60 min；在一定范围内提高模板分子浓度，增大重氮甲烷用量，采用形成氢键能力较弱的溶剂，均能提高修饰效果。

No time counter method is used to select collision molecules and diffuse reflection model is used to simulate the collision between molecules and body surface.

采用NTC方法对分子碰撞对进行抽样碰撞处理，分子与物面的碰撞则采用了漫反射模型进行处理。

It indicates that the N—O bonds in the singlet dimer adsorption configurations are weaker than any other structures, and this is propitious to the NO direct decomposition. 7. Unlike NO molecules interaction with copper atoms, when two NO molecules interact with the adjacent silver atoms, the non-planar structures are more stable than the planar.

同时，单重态的二聚体与相邻的金属铜和银原子作用时，由于电子从金属原子转移到二聚体上的数量最多，因此在这种吸附构型中，金属原子被离子化的倾向最大，同时使得二聚体中N—O键被削弱的程度也最大，有利于NO的直接分解； 7。

The two molecules get closer, the electron cloud overlap, so that two molecules repel each other.

两个分子靠得更近时，电子云互相重叠，使两个分子互相排斥。

The calculated results indicate that there are two absolutely opposite regions in the vicinity of 5-FU. In one of the regions, water molecules can assist the tautomerism from 5-FU to its enol form 5-FU(superscript *, whereas in another region, water molecules can protect 5-FU from tautomerizing to 5-FU(superscript *).

研究发现，在5-氟尿嘧啶周围存在两类不同的区域，在其中一类区域中，水分子能促进质子转移的发生；而在另一类区域中，水分子却能阻碍质子转移的发生。

However, by taking advantage of the steric restriction offered by the three ethoxyl groups on the heads of the C8TES molecules, as well as the difference of the chemical activities between the OTS and C8TES molecules, it was possible to construct both the homogeneously and phase-separated mixed C8TES/OTS SAMs by means of the stepwise method.

但是利用C8TES分子头部三个乙氧基所形成的空间位阻以及C8TES和OTS分子之间反应活性的差异，采用分步法可以制备出混合均匀的均相和相分离(Phase-separated)的C8TES／OTS混合自组装单分子膜。

But you do a trick, you put little dye molecules, florescent molecules; think of it as a string of Christmas tree lights.

这篇采访其实是伯克利大学的采访的系列，英文功底好的人强烈建议读一读，也有视频可以在线观看。

The effect of heterocycle in the molecules was similar to that of group -NH2, but the hydrogen on the nitrogen atoms could form the hydrogen bond between molecules which could effectively improve the thermal stability.

对于二维电荷转移体系，我们研究了氧桥Λ型分子，它含有两个D-π-A轴，属于典型的二维电荷转移体系，且它们的β_／β_＜1。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
