有两个分子的

Strong covalent bond held two or more atoms together, but only weak intermolecular exist between molecules.

有强作用力的共价键把两个甚至更多的原子结合在一起，但是只有微弱的作用了存在于分子之间。

In the titration experiment of NMR and IR spectroscopy, we can understand how sensors binding with metal ions: the two carbonyl group and crown ether group cooperated in binding with metal ions. Furthermore, by altering the "oxygen" atoms of crown ether to "sulfur", we can change the binding affinity to the soft metal: cupper. It shows 60-fold enhancement of fluorescence.

在化合物2中，我们引进了硫原子在冠状醚中，则应对电子密度较低之金属有较好的结合能力，实验结果显示了此分子对铜离子有相当好的选择性和结合能力，萤光增加可达60倍；同时由红外光吸收光谱和核磁共振光谱滴定实验可确知，香豆素衍生物上的两个羰基对金属离子的选择性及结合上扮演相当重要的角色。

Congregation obtained after chitosan k and a treatments showed more tightness than sediments obtained without chitosan treatment, sediments after chitosan b and c treatments were network in structure. Mixed systems of pectin, protein and polyphenol were applied for studying a simulated system of kiwifruit juice. It was shown that the aggregates of pectin molecules in pectin solution were dispersing tubular globules. Particles in mixed solution of pectin and bovine serum albumin had two states: one was circular in photo, the other contained single particle or aggregates of several particles. Pectin decreased the interaction between protein and polyphenol and strengthened the stability of mixed solution of pectin, protein and polyphenol. Chitosan flocculated mixed solution of pectin, protein and polyphenol, and the floccule was white, having a network structure.

用果胶-蛋白质-丹宁酸混合体系作为猕猴桃原果汁的模拟体系研究结果表明：1、果胶溶液中果胶分子聚集物呈中空球形均匀分散；2、果胶／牛血清白蛋白混合溶液中的球形粒子有两种：粒子中央光线可透过，照片上呈环形；粒子的中央包含有单个或多个球形粒子的聚集体，认为粒子的中央是蛋白质，外层是果胶；3、果胶的存在抑制或减弱了蛋白质-丹宁酸之间的相互作用，果胶起到防止蛋白质-多酚产生沉淀的作用，增强了溶液的稳定性；4、壳聚糖加入果胶-蛋白质-丹宁酸混合溶液中时，可以絮凝果胶-蛋白质-丹宁酸混合溶液，溶液中出现白色的网状絮凝物。

In the first paper, magnet-lab biologists Michael Davidson and Kristen Hazelwood worked with researchers from the University of Alberta to create two new fluorescent-protein biosensors, molecular "beacons" that can tell if there is activity within a cell.

在第一份文件，磁体实验室的生物学家迈克尔戴维森和克里斯汀 hazelwood工作与研究人员从艾伯塔大学，以创建两个新荧光蛋白的生物传感器，分子"信标"它可以告诉，如果有活动的一间囚室。

Photoionization process of NaI molecule always occurs accompanying dissociation process and these two processes are competing.

在NaI分子的光电离过程中伴随有解离过程，并且这两个过程是相互竞争的。

The reaction takes place as soon as 3a is dissolved in solution. With the presence of a tethering terminal vinyl group bound to the vinylidene ligand, the [2+2] cycloaddition of two C=C double bonds readily occurred.

当有一乙烯基键结在丙二烯基上，分子内的两个碳碳双键会马上发生[2+2]的环化加成反应。

The allegations of a possible link to the case known as " Unabomber " dumbfounded friends and co-workers who knew Ivins as a gentle, bighearted family man who raised two children in Frederick, volunteered for community charities and played keyboards for the local Catholic church.

这些关于埃文斯涉及&邮寄炸弹恐怖分子&的指控使得他的朋友们和同事们大为震惊。他们所认识的埃文斯，是一个温和，大度的顾家男人，在弗雷德里克有一个家庭，抚养两个孩子，志愿参加社区慈善活动，在当地的天主教堂弹琴。

That's less than passenger car mortalities.

没有恐怖分子会对你们两个有兴趣的

Compared with spotted seals along Sea of Japan and Sea of Okhotsk, spotted seals in Liaodong Gulf have relative less haplotypes and lower genetic diversity, and have one insertion at site 16296 of mtDNA, which could be a marker between these populations.

辽东湾斑海豹mtDNA的16296位点即苏氨酸tRNA基因序列的最后一位有1个C碱基的插入，16607位点存在T/C转换，这两个变异位点是鉴别辽东湾斑海豹与日本及鄂霍次克海区斑海豹的重要分子标记。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
