在阿联酋的固执下，OPEC+不得不又一次上演“拖字诀”，让本就紧张不已的市场再次绷紧了神经。不过，可以明确的是，增产几乎是板上钉钉了，毕竟这半年来，油价的飙升有目共睹，再加上全球复苏稍微进一步推进，库存减少，供需两端也在日趋平衡。阿联酋再“刚”，顶多也就是为自己的增产多谋点利。现在的问题在于幅度，一旦稍多，或许又会见证一次崩盘。

北京时间7月6日凌晨，全球投资者再度空等一场。由于沙特与阿联酋之间的分歧始终未能得到有效解决，备受全球关注的OPEC+产量控制会议，在延期数次后无果而终。随着全球油市的持续向好，油价也连续刷新三年以来的新高，OPEC+需要增产抢占市场份额，同时也为火热油市降温已经成为产油国共识；但阿联酋意图进一步提升产量，作为OPEC+组织领头羊的沙特则持反对态度。OPEC+组织部长级会议原定于维也纳当地时间7月5日15点举行，但由于会外讨论仍旧未能解决阿联酋与其他产油国的分歧，两个多小时后，沙特与俄罗斯共同取消了这次会议。

“我们也意识到在中国市场上有很多的车企在布局增程式动力车型。目前市场上的增程式技术与e-POWER技术最大的区别在于电池容量。理想ONE、岚图FREE的电池容量都在30千瓦时以上。与之相比，日产e-POW-ER系统的电池容量是1.5至1.8千瓦时。当前，动力电池的价格仍然处于高位，因此电池的容量变小，可以使电池成本大幅降低，最终可以使消费者以更低的价格购买电动车。第二点区别在于，电池容量变小后，电池占据的车内空间也会变小。这样的话，消费者可使用的车内空间也会相应变得更宽敞，驾乘体验更舒适。可以说，搭载e-POWER技术的车型在愉悦的驾驶体验与燃油经济性之间实现了相对的平衡。”近日，就日产汽车e-POW-ER技术与传统增程式混动技术之间的不同相关话题，日产（中国）投资有限公司副总经理佐佐木博树（Hiroki Sasaki）在接受媒体记者专访时表达了上述观点。

上周，德尔塔变异毒株持续扩散，世卫组织称该毒株已在至少98个国家和地区出现，且在持续变异和进化。受变异株入侵影响，多国单日新确诊病例数回升，新一轮疫情已逼近。世卫组织呼吁各国加快疫苗接种，确保一年后每个国家70%的人口都接种新冠疫苗。市场方面，美国楼市火爆。4月房价指数创下1987年来最大同比涨幅，但房屋销售量却有所下滑。市场认为，当前的低贷款利率、购房需求回升、房屋库存不足是影响楼市的主要因素

The global commercial hand dryer market mainly includes two product segments: hot air and jet air hand dryers. Hot air dryers use the traditional technology of evaporating water to dry hands, whereas the jet drying system is capable of blowing the water away from the hands within a few seconds. Further, the hot air system has also undergone numerous technological advancements with due course of time. Taking demand into consideration, both products are widely popular among endusers. In the present scenario, the market is dominated by hot air hand dryers in terms of unit sales and revenue. However, jet air dryers accounted for almost the same revenue generation. One of the key reasons for this is the pricing difference between hot air and jet air dryers.
