，这一点在WPS下载最新地址中也有详细论述
By WWII, scientists had already begun looking at alternative gelling substances for routine use in bacteriology, but concluded that agar was still better as it is both firmer and easier to handle. Today, some specialized microbiology applications use the colloid carrageenan (extracted from red seaweed Chondrus crispus, or “Irish Moss”), a more transparent and less auto-fluorescent alternative to agar (agar emits its own background fluorescence when excited by light). However, for routine bacteriological use, carrageenan is more difficult to dissolve, requires higher concentrations, can degrade at high temperatures, and forms weaker gels, which may result in puncturing its surface during the plating of cells.
第十条 国家加强原子能领域标准体系建设，推动、参与原子能领域国际标准化活动。
例如，医药制造业在2024年面临融资困境、药品集采等多重压力，叠加研发管线同质化等问题，从过去的粗放式发展转向集约化调整；再如交通运输、仓储和邮政业，正在经历智慧化转型，快递物流龙头的研发投入出现分化现象。
