查询词典 helix

Many of today's scientific headlines—the deciphering of the DNA of humans and other species, the transplanting of genessintosanimals and crops to change their traits, the use of gene therapy to treat disease, the DNA evidence that exonerates people imprisoned unjustly—ultimately came from the double helix discovery.

许多今日科学界的热门话题，诸如人类和其他物种的DNA密码破解，将基因移植到动物或植物体内以改变其生物特征，应用基因疗法治疗疾病以及依靠DNA证据使被错误监禁的人恢复清白，都最终源自双螺旋分子结构的发现。

And, the design of grouted helix anchor can adopt the partial material safety factors method.

The first feature of the model is the essence of each helix transformation; the second feature of this model is the inter-impact among these triple helixes; the third feature is the triple network and the re-superposition generated from the interaction among these triple dimensions.

为此，本论文得出以下几个方面的结论：(1)政府、产业和大学&三重螺旋&是一个创新模式，这一模式抓住了在知识资本化进程中，不同阶段制度安排的多元互惠关系。

As for dopamine, it intercalates into the double helix of DNA in the range of 5. 0×10〓 to 9. 0 ×10〓 mol/L.

实验结果表明，低浓度的多巴酚丁胺和肾上腺素与DNA之间主要为静电作用；而在高浓度时，则主要为插入作用。

As for dopamine, it intercalates into the double helix of DNA in the concentration range of 5.00×10^(-5) to 9.00×10^(-4)mol/L. The binding constants of dopamine, adrenaline and dobuamine with DNA are determined as 1.55×10^3, 9.77×10^3 and 1.74×10^4L/mol, respectively, by electrochemical method.

对于多巴胺，在5.00×10^(-5)~9.00×l0^(-4)mol/L范围内，它与DNA之间主要为插人作用，同时，采用电化学方法测得多巴胺、肾上腺素和多巴酚丁胺与DNA之间的表观结合常数分别为1.55×10^3，9.77×l0^3和1.74×10^4L/mol。

The results shown that both [Cu_2]~2+ and NR molecular can intercalates into the DNA double helix layer, and there is a competition between these two interactions. Furthermore, chemometrics approach, parallel factor analysis, was used to resolve the measured three-way CW-SFS data, which provided simultaneously the concentration information for the three reaction components, NR, [Cu_2]~2+ and NR-DNA, for the system at each equilibrium point. This PARAFAC analysis indicated that the intercalation of the [Cu_2]~2+ molecule into the DNA proceeds by exchanging with the NR probe, and can be attributed to two parallel reactions.

本工作以同步荧光技术采集了竞争作用的三维数据，并结合了化学计量学中的平行因子法对此三维数据进行分解，得到了各组分的荧光光谱图及各个反应平衡点各组分的相对浓度，平衡浓度的变化趋势也表明了铜络合物与中性红之间的竞争作用，进一步表明了铜络物与DNA的作用方式和中性红与DNA作用方式一样均为嵌插作用。

Part 2In this study, we have shown with the use of UV-visible spectrophotometry and the constant wavelength synchronous fluorescence spectroscopy techniques that the pharmaceutical drug, chlorpromazine hydrochloride, intercalates into the deoxyribonucleic acid double helix by partial exchange with the Neutral Red molecular probe.

第二部分，本工作结合紫外可见分光光度法和三维同步荧光法分别研究了中性红、盐酸氯丙嗪与DNA的作用，并利用中性红作探针来进一步研究盐酸氯丙嗪与DNA的作用以及它们二者与DNA之间的竞争作用。

So, when designing novel intercalating ligand, the charge distribution and streic interaction should be emphasized. 4. Comparison on the modeling of DNA helix with different conditions.

这就提示我们，采用esff力场在水溶液环境中对本论文中的系列作用体系进行模拟是合理的，但是在真空环境中可能会出现结构损坏，进而影响到对识别结果的深入分析。
