在头部行业中，半导体业下滑较为明显——在披露研发人员的企业数量增长47.58%的情况下，研发人员增速仅为7.71%，导致平均值的跌幅达到27.02%。叠加研发投入五年增长53.87%，说明该行业的资金优先投向了技术与设备，而非人力扩张。
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.
