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.

“一颗芯片，真正要达到回本，没有几百万颗的出货量肯定做不到。”芯擎科技创始人、董事兼CEO汪凯曾如是坦言。按此行业标准衡量，蔚来主品牌年销30余万辆的体量，远未达到让神玑芯片实现规模摊销的门槛。当竞争对手通过百万级销量将先进制程芯片成本摊薄时，蔚来仍在为每一颗神玑芯片支付高昂的溢价——这部分成本最终将反映在车价上，进一步削弱其市场竞争力。，更多细节参见旺商聊官方下载
