fluorescence

fluorescence的音标为：[fluəˈresns]，基本翻译为“荧光”，速记技巧为：flu（荧光）+ ren（人）→荧光。

fluorescence这个词源自拉丁语fluere（流动）和light（光），意思是“发光”或“荧光”。它的变化形式包括名词fluorescence（荧光）和形容词fluorescent（荧光的），后者还可以变为副词fluorescently（荧光地）。

英文小作文：

Fluorescence is a fascinating phenomenon that can be used in a wide range of applications, from basic research to industrial production. When light interacts with certain substances, they can emit light of a different color, known as fluorescence. This phenomenon is used in various fields, including medicine, biotechnology, and security. In medicine, fluorescence imaging techniques allow for the visualization of internal structures and diseases with high precision. Biotechnology uses fluorescent labels to identify and study cells and molecules, while security checks use fluorescent dyes to mark and identify objects. However, fluorescence is not limited to these applications, and it can also be used in other fields such as environmental monitoring and material science. The future of fluorescence is bright, as it offers new possibilities for research and development in various fields.
