德媒《商報》評論，此行默茨雖帶龐大商團，但行前缺乏重大投資公告，似乎顯示默茨意在「談未來合作」而非「單純向中國求援」。因此，北京行更像是一場「有限接觸」的試探，旨在測試中國在兩國貿易「失衡」下的讓步意願。
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.
