在地铁坐(站)满4小时,你的身体会发生什么变化?
3 6 Ke· 2025-10-11 09:28
灵魂拷问:十一长假结束,你们今天上班吗? 相信有相当多的朋友,要在拥挤沉闷滂臭的地铁上呆很长时间。 向这一部分人(包括我自己)致以最隆重的同情。我们今天来拆解一下地铁里的空气。以及这些空气对 人体的影响。 科学家曾对北上广地铁内的空气质量做过测量,雾霾天的时候,地铁车厢中空气质量也相应变差。不要 以为进了地铁站就安全了,口罩给我戴好! 先前的一些研究显示,日常生活环境里的空气污染会影响到人们的心血管健康。地铁车厢内的空气质量 不佳,是不是也会带来同样的影响? 有趣的是,这种影响看似对女性的作用更大。研究数据表明,PM0.5的上升,会引起女性高达34.87%的 SDNN下降。在男性中,该数据仅为6.05%。 研究人员注意到,空气中的黑碳同样会对心率产生影响。黑碳浓度的升高与SDNN的降低同样呈相关关 系。随着时间的推移,SDNN下降趋势愈加明显。志愿者在地铁车厢内待了5分钟后,相关数据只有 0.84%。而待了1小时和2小时后,该数据分别为2.22%与4.44%。 地铁通勤族的注意事项 北京大学公共卫生学院郭新彪教授与邓芙蓉教授曾主导了一项研究。结果表明,地铁车厢里的颗粒物可 能对健康成人的心率变化产生短期影响。 ...

关税战第三次延期?美国的底气正在消失,谁才是世界第一大经济体
Sou Hu Cai Jing· 2025-10-02 03:48
一直以来,美国在对外贸易争端中往往采取主动进攻的策略,其他国家则通常处于被迫接受的状态。但这一次,中美之间的博弈出现了意想不到的反转:作 为"全球老大"的美国,居然一再选择暂时妥协。 按理说,美国的财政工具、金融影响力和强大的军事力量,似乎应该能给它足够的底气。但在与中国的贸易较量中,美国却一次又一次作出退让,这背后到 底是为什么? 许多人常听到一句话:"美国仍然是世界第一大经济体,中国还需要追赶。"表面上看,这句话似乎没错,因为根据名义GDP的数字,美国依然领先。但如果 换一个角度来看,考虑到购买力平价和真实工业产出的因素,情况就完全不同了。 这正是中国的优势所在。中国拥有全球最大的工业生产能力,掌握了钢铁、水泥、铝、稀土、化工和新能源等关键产业,几乎形成了世界最完整的工业链。 中国的钢铁产量占全球的半壁江山,铝的产量接近六成,化工产品也占全球超过六成。这些工业基础原材料的产能决定了一个国家在全球危机中的自给自足 能力。 根据购买力平价的计算,中国的经济规模早已超过美国,也就是说,全球最大的价值创造正在东方发生。单单从虚拟经济中的数字来看,确实容易产生误 判。但是,真正决定一国综合实力的,还是在工业生产、资 ...
美元地位越来越弱?全球结算占比不足50%,人民币强势抢夺市场
Sou Hu Cai Jing· 2025-09-29 16:17
Group 1 - The recent discussions around Hong Kong brokers checking Chinese accounts and the removal of mandatory foreign exchange settlement are seen as part of a natural economic evolution rather than confrontational actions against the dollar [2][5] - The account checks in Hong Kong are aligned with global capital regulation trends, aiming to distinguish between legitimate investors and those engaging in illegal activities [5][6] - The removal of mandatory foreign exchange settlement reflects a long-term policy shift that allows businesses to manage currency risks based on their needs, rather than a sudden rejection of the dollar [8][24] Group 2 - The value of currency is fundamentally tied to its ability to be exchanged for real productive capacity, rather than being anchored to commodities like gold or oil [10][11] - Historical examples illustrate that an increase in currency supply without a corresponding increase in production leads to inflation and currency devaluation [11][13] - The current global reliance on the dollar is diminishing as other economies, such as Russia, are willing to accept currencies like the yuan for trade, reflecting a shift in production capabilities [15][18] Group 3 - The long-term trend indicates that the yuan is likely to appreciate gradually due to China's significant manufacturing capacity, which surpasses that of the US, Japan, and Germany combined [20][22] - The gradual appreciation of the yuan is intended to protect export-oriented businesses from sudden cost increases, allowing them to transition towards higher quality and brand-focused strategies [22][24] - Despite the yuan's current small share in global trade settlements, its usage is steadily increasing, particularly in trade with ASEAN and Russia, indicating a gradual expansion rather than a complete replacement of the dollar [24][26]

又征新关税?美政府借由“国家安全”,对多个行业启动调查
Huan Qiu Shi Bao· 2025-09-25 22:32
此次美国商务部开展调查的依据依旧是《贸易扩展法》第232条款,此前美国政府已动用该条款对汽车 及其零部件、铜、钢和铝加征了关税,同时,针对药品、半导体、中重型卡车等产品的进口调查仍在进 行。若这些行业性调查最终导致加征关税,将与美国此前按国别征收的关税叠加执行。 本轮调查正值各贸易伙伴艰难推进与美国的关税谈判之际,各经济体进展不一。当地时间周三,美国政 府发布公告,确认美欧贸易协议生效,意味着7月底美欧达成的框架协议时隔两个月正式实施。不过据 彭博社24日报道,欧盟委员会负责贸易和经济安全的委员谢夫乔维奇本周将在吉隆坡东盟部长级峰会期 间会晤美国贸易代表格里尔,希望重启陷入停滞的钢铁和铝出口关税谈判。 【环球时报报道 记者 李迅典】美国商务部9月24日证实,美国政府已对机器人、工业机械以及医疗设备 进口启动了新一轮的"232条款"调查,以评估此类进口是否威胁美国国家安全。据美国CNBC网站25日 报道,该调查于9月2日开始,但直至本周才被披露,此举可能成为新一轮行业关税的依据,或将增加消 费者、医院、患者以及制造商需要承担的成本。 格里尔周三表示,美国预计将在未来数月内与更多东南亚国家敲定贸易协议。路透社报道 ...

美国政府为扩大关税铺路:对机器人、工业机械及医疗器械进口展开调查
Zhi Tong Cai Jing· 2025-09-24 23:49
(原标题:美国政府为扩大关税铺路:对机器人、工业机械及医疗器械进口展开调查) 智通财经APP获悉,特朗普政府对机器人、工业机械和医疗设备的进口产品展开了调查,这为实施新的关税措施奠定了基础。根据美国联邦公 报,美国商务部正依据《贸易扩展法》第 232 条开展相关调查。调查于 9 月 2 日启动。根据该法律,总统有权对被认为对国家安全至关重要的商 品征收关税,而美国商务部需在 270 天内提交其政策建议。 这些新的调查反映了特朗普政府一些官员对于美国在诸多医疗用品(包括注射器、缝合线、导管和纱布)方面过度依赖外国供应商的担忧。美国商 务部还将审查个人防护设备的贸易情况,比如在新冠疫情期间随处可见的防护手套和口罩等产品。 新公布的医疗设备调查将不涉及处方药、生物制剂以及其他药品,这些药品的审查工作已经在商务部的另一项调查中进行了。 根据公告内容,此次对机器人及工业机械的调查将重点针对计算机控制的机械系统、铣床以及工厂中广泛使用的冲压和压装设备。 相关ETF 食品饮料ETF (产品代码: 515170) 新公布的调查扩大了可能受到关税影响的行业范围,而特朗普希望通过提高进口商品的成本来鼓励关键行业的国内制造业发展。 ...
