Agar was first introduced into the laboratory in 1881. Since then, microbiologists have depended on agar to create strong jellies. When microorganisms are streaked or plated onto this jellied surface and incubated, individual cells multiply into distinct colonies that scientists can easily observe, select, and propagate for further experiments. Many of the most important findings in biological research of the last 150 years or so — including the discovery of the CRISPR/Cas9 gene-editing tool — have been enabled by agar.4 Agarose, a derivative of agar, is also essential in molecular biology techniques like gel electrophoresis, where its porous gel matrix separates DNA fragments by size, enabling researchers to analyze and isolate specific genetic sequences.

百年党史峥嵘。中央党校内，立于广场上的一块巨石两面，“实事求是”“为人民服务”的箴言格外醒目，校园两侧，焦裕禄、谷文昌塑像静立，映照始终不渝的初心、不随境迁的追求、不为时易的坚持。
支持者自有另一套逻辑：AI 并不储存书里的内容，而是从中提取语言规律，这更像是一个人博览群书之后形成自己的表达。这个类比并非毫无道理，但却省略了一个关键差异：
