查询词典 molecules

So when you step on a patch of ice, you exert pressure on the ice, which causes its molecules to move closer together. That makes them revert to their more dense state, which is water.

所以，你踏上一片冰时，就会对它产生压力，这个压力导致其分子更加聚集，使之重新回复到更加紧密的形态--水。

Therefore, this work has an value for probing the interaction mechanism of as and molecules.

对进一步研究原子与分子相互作用的机制有一定的参考价值。

Both prokaryotic and eukaryotic cells also encode genetic information in DNA molecules.

原核和真核细胞编码的遗传信息都在DNA分子内。

The Ids RNA or siRNA obtained by said invention is mixed with hepatitis B virus expression vector in proper proportion, and injected into the mouse body by vane caudalis hydraulic pressure method, and its result shows that the non-homologous sequence IdsRNA and siRNA basically do not inhibit the replication of hepatitis B virus in mouse body, and these RNA molecules are mixed with hepatitis B virus gene.

将本发明得到的ldsRNA或siRNA以适当的比例与乙型肝炎病毒表达载体混合，并用尾静脉液压法注射到小鼠体内。结果显示非同源性序列ldsRNA和siRNA基本不抑制乙型肝炎病毒在小鼠体内的复制，而与乙肝病毒基因同源性的ldsRNA和siRNA可以有效抑制乙型肝炎病毒在小鼠体内的感染复制，抑制率高达90％以上。

The results indicated that the composite films exhibited much improved gas sensing performance.The phthalocyanine and its a-Fe2O3 embedded nano-particulate LB filmswere prepared by Langmuir-Blodgett technique. The films were characterized by AFM, UV-Vis and FT-IR spectra. The results indicated that the embedded LB films were composed of a-Fe2O3 nanoparticles and isopropoxyphthalocyanine molecules. The gas sensitivity of such prepared composite LB films was greatly improved. The film could detect 5ppm of propyl alcohol at room temperature. The composite films could be considered as gas-sensors for alcohols.

利用LB技术制各了异丙氧基酞菁铜LB膜和酞菁铜包埋球形α-Fe_2O_3纳米粒子的杂化LB薄膜，对其AFM、紫外和红外光谱的研究表明，利用LB技术可以实现酞菁与α-Fe_2O_3纳米粒子的有序组装，而且杂化薄膜对醇类气体的灵敏度有较大幅度提高，如对浓度为5ppm正丙醇的灵敏度为3.85，因此，杂化薄膜可以作为室温下醇类气体传感器进行开发研究。

Protoplasm is water, salt, organic molecules and various enzymes composed of catalytic reaction.

原生质是由水、盐、有机分子及各种催化反应的酶所组成。

The aim was to research on relationship between quorum sensing signal molecules and characteristics of spoilage in Pseudomonas.

本研究的目的是确定假单胞菌群体感应信号分子与腐败特性的关系。

The result showed that the assembly of the constructed molecules agreed with the actual mid-boiling points, the concentration of structural groups, average molecular weights, and the ring and side chain distributions. The correlation of properties between pure compounds and complex mixtures of heavy oils could be built by the proposed method.

验证结果表明，除个别结构基团的摩尔质量误差较大外，构建分子系综中沸点、统计结构基团的摩尔质量、相对分子质量、环和侧链分布均与实测值相近，与重油组成具有等效性。

The difference between the test groups and the control group was statistically significant. It could be deduced that all the insecticides tested in this experiment damaged the spiders′ intestinal mucosa, compromising its function as a barrier and letting large molecules such as FTIC-D more easily penetrate. Among the insecticides, pyrethrin and Bt preparation are bio-insecticides, and the FITC-D concentrations of the spiders exposed to these two bio-insecticides were more than those of the spiders exposed to the chemical insecticides imidacloprid and dipterex. The difference between the bio-insecticide groups and the imidacloprid group was significant, but there was no significant difference between the bio-insecticide groups and the dipterex group.

结果表明：4种杀虫剂处理后拟环纹豹蛛血液中的荧光素浓度远高于对照组，各个处理组拟环纹豹蛛血液样本中的荧光素浓度均与对照组存在极显著差异，可见4种杀虫剂均将对拟环纹豹蛛肠黏膜的屏障功能造成损伤，导致大分子物质易于通过；其中1.5%除虫菊素水乳剂三保奇花和Bt制剂强杀处理后拟环纹豹蛛中肠黏膜的通透性高于仿烟碱类化学杀虫剂吡虫啉处理组，差异达到显著水平，但与有机磷杀虫剂敌百虫处理组差异不显著。

The electrochemical and spectrometric studies on the interactions of two organic dye molecules, malachite green and pyronine B, with DNA have been described in this paper.

本论文以电化学和紫外-可见光谱方法研究了两种有机染料小分子孔雀石绿和吡哕红B与dsDNA的相互作用。

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。
