近年来，张连起走访多家不同领域企业并开展专项调研，了解到行业“内卷”的根源在于创新能力不足、产品与服务同质化严重，导致企业依赖降价手段争夺市场，这又进一步导致企业利润下降、研发投入缩减。

3rd over: India 14-0 (Rawal 11, Mandhana 3) Mandhana stretches to make use of Schutt offering too much width for a single to deep point. Schutt has the ball moving around but Rawal hits against the swing into her to crunch the first boundary of the innings through cover. Rawal repeats the shot for the same result as the fast outfield favours the batters.

"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.
