查询词典 chromogenic

To determine the condition of chromogenic reaction between iodine and amylum quantitatively, the author studied the law in the course of chromogenic reaction between iodine and amylum with the aid of spectrophotometer quantitatively, and found that maximum absorption wavelength is 610 nm, and the absorbance in the course of chromogenic reaction between iodine and amylum has not changed within 7 hours.

为了确定碘和淀粉反应的定量关系，本文利用分光光度计定量地研究了碘和淀粉显色反应过程中吸光度的变化规律，发现碘和淀粉显色反应的最大吸收波长为610 nm，碘和淀粉显色反应的吸光度在七小时内基本不变，可以进行比色分析。

UV 254nm, 366nm and anisaldehyde as a chromogenic agent were used for detecting compounds of these strains. Results indicate that the metabolites of these strains were the most abundant when these strains were fermented in No.1 and No.4 media, and only few in No.2 and No.3. Metabolites of each strain were different in different media.

实验结果表明，用1号和4号培养基发酵产生的次生代谢产物的种类最丰富，2号和3号培养基产生的较少；用II号展层系统(氯仿∶甲醇=4∶1)和III号展层系统(正丁醇∶乙酸∶水=4∶1∶5)作TLC层析，检测到的产物最多；3种检测方法以茴香醛检测到的代谢产物最丰富。

Three developing systems were used for chromatography of TLC. UV 254nm, 366nm and anisaldehyde as a chromogenic agent were used for detecting compounds of these strains.

本研究设计4种内生菌发酵培养基，对89株分离自傣药植物且具有高抗菌活性的内生菌及5株潜在放线菌新种进行摇瓶发酵，发酵液的提取物用3种展层系统作薄层色谱展层，用UV(254nm、366nm)和茴香醛试剂进行检测。

The testing method contained fibrin plate assay, direct and indirect chromogenic assay, SDS-PAGE fibrin autography, and visual exhibition of the complexes between rPAI-1 and t-PA or low molecular weight u-PA on SDSPAGE.

所使用的方法包括：纤维蛋白平板法，直接和间接的显色底物法，SDS-PAGE纤维蛋白自显影法，以及用SDS-PAGE直接显示rPAI-1与t-PA和低分子量u-PA形成的复合物。

If he is a geologist, he will be completely engrossed in observing the vivid colors produced in sections of rock by polarized light; if a bacteriologist, he will develop a delight in collecting and cultivating the various chromogenic and phosphorescent microbes; and if an astronomer, he will devote his leisure moments to photographing the mountains on the moon or the spots on the sun.

在他崇拜矽藻的狂热里，他把全部的时间花在欣赏每一种矽藻，以千奇百怪的角度，替它们照相，来显现它的美丽，把这些美丽的藻类排成一个符号，甚至把它艺术化，排成一个矽藻的浮雕，甚至把它排成像盾牌一样的各式各样徽章，或者是装饰用的设计。
