China's digital industry revenue tops 20 trillion yuan in H1_我的网站

A |     加州大学戴维斯分校的研究人员发现，当接触到普通的家庭噪音时，人们可能认识不到他们的狗有压力。

B |     (ECNS) -- China's digital industry generated 20.71 trillion yuan (about $2.86 trillion) in revenue in the first half of the year, up 13.6% year on year, according to data released by the Ministry of Industry and Information Technology (MIIT) on Tuesday.    The growth rate rose by 4.1 percentage points from a year earlier and 0.7 percentage points from the first quarter.        Driven by domestic demand for artificial intelligence and strong exports, sector profitability improved, with total profits reaching 1.79 trillion yuan, up 19.3%. The profit margin climbed to 8.6%.    Digital industries remain concentrated in eastern provinces. Guangdong, Jiangsu, Beijing, Shanghai and Zhejiang were among the top 10 regions, together generating 17.21 trillion yuan, or 83.1% of the national total, and contributing 87% of overall growth.    Central China reported digital industry revenue of 2.86 trillion yuan, up 28.3% year on year, accelerating by 18.7 percentage points from a year earlier and outpacing the national average by 14.7 percentage points. Anhui and Hubei provinces led the growth.    MIIT said 16 national‑level advanced manufacturing clusters have been established in sectors including integrated circuits and AI, cultivating backbone enterprises that drive innovation, industrial upgrading and competitiveness.    (By Tang Yuxian)                    。虽然人们公认突然的巨大噪音，如烟花爆竹或雷暴，通常会引发狗的焦虑，但一项新的研究发现，即使是普通的噪音，如吸尘器或微波炉，也会成为一个诱因。这项研究发表在《兽医科学前沿》（Frontiers in Veterinary Science）上。研究发现，高频、间歇性的噪音，如烟雾探测器电池即将耗尽的警告，更有可能引起狗的焦虑，而不是低频、连续的噪音。我们知道有很多狗对噪音敏感，但我们低估了它们对我们认为正常的噪音恐惧，因为许多狗主人不能读懂身体语言。
狗狗焦虑的一些常见迹象包括畏缩、颤抖或退缩，但当行为更加微妙时，主人可能不太能够识别恐惧或焦虑的迹象。例如，压力大的狗可能会喘气，舔嘴唇，把头转过去，甚至身体僵硬。有时它们的耳朵会向后转，头会低到肩膀以下。

C | 研究人员对386名狗主人进行了调查，了解他们的狗对家庭声音的反应，并检查了网上提供的62个视频中记录狗行为和人类反应。

D | 研究发现，主人不仅低估了狗的恐惧感，而且视频中的大多数人的反应是娱乐，而不是关注狗的福利。研究人员希望这项研究能让人们思考可能给狗带来压力的声音来源，这样他们就可以采取措施，尽量减少他们的狗接触到这些声音。

E | 由于狗的听觉范围更广，一些声音也可能对狗耳朵造成潜在的痛苦，如非常响亮或高频率的声音。

F | 尽量减少接触可能很简单，比如更频繁地更换烟雾探测器的电池，或者把狗从可能发生巨大噪音的房间里带走。
