在上海居住多年的德商麥永剛((Juergen Meyer)向BBC中文指出,即便德國盼望平衡雙邊貿易需求,但德企去風險化的工作遠遠不足,抵禦中國進口衝擊,不僅是汽車產業,德國的生物科技及化工產業情況都很險峻。
Therefore, Ahmed, who is based in London, said it was difficult without more research to know exactly what is behind the rise in cases.

"Tuning frictional behavior on the fly has been a long-standing engineering dream," said co-author Katia Bertoldi of Harvard University. "This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.” In addition, the dynamics revealed by these results are similar to those of tectonic faults and thus give scientists a new model for the mechanics of earthquakes, according to their new paper published in the journal Nature.
