chromatography

chromatography的音标为["krəʊmətəgrəfɪ]：色谱法。

基本翻译为“色谱法”，这是一种分析化学中常用的技术，可用于分离和鉴定各种化合物。

速记技巧：可以将chromatography看作是“chroma（颜色）+graphy（图表）”，暗示它与绘制图表有关，从而帮助记忆。

Chromatography这个词源于希腊语词根chroma（颜色）和graphos（写、画），表示通过色层分离物质的方法。它的变化形式主要有chromatogram（色层图）和chromatography（色层法）。

英文小作文：

Chromatography is a powerful tool for separating and analyzing substances. It can be used to separate complex mixtures into their individual components, or to purify biologically active substances such as proteins and antibodies. Chromatography can be performed using a variety of techniques, including column chromatography, thin layer chromatography, high performance liquid chromatography, and affinity chromatography. Each technique has its own advantages and disadvantages, and is best suited for different types of samples and analysis goals. However, regardless of the technique used, the key to successful chromatography is careful experiment design and accurate data analysis.
