霍尔木兹大消息 美方：约40艘油轮通过海峡 运出1600万桶原油！特朗普：那里现在就是美国领土！_我的网站

一 |     　　据美国方面当地时间22日消息，三名美国官员称，21日晚间，有约40艘油轮通过霍尔木兹海峡南侧航道，向外运出原油约1600万桶。    A team of scientists has discovered a likely explanation for why one may feel exhausted after engaging in intense cognitive work.,In their study, published in the Current Biology last week, the researchers argue that intense cognitive work, when it lasts for several hours, results in the buildup of potentially toxic byproducts in the prefrontal cortex part of the human brain, which then affects a person’s behavior.,“Influential theories suggested that fatigue is a sort of illusion cooked up by the brain to make us stop whatever we are doing and turn to a more gratifying activity,” Mathias Pessiglione of Pitié-Salpêtrière University in Paris, said as quoted in a news release by Cell Press. “But our findings show that cognitive work results in a true functional alteration—accumulation of noxious substances—so fatigue would indeed be a signal that makes us stop working but for a different purpose: to preserve the integrity of brain functioning.”,During the course of their research, the team employed magnetic resonance spectroscopy to monitor the brain chemistry of two groups of people during a workday, with one group performing easy cognitive tasks while the other engaged in more complex mental activities.,Only the latter group ended up exhibiting signs of fatigue, as well as a tendency to favor “options proposing rewards at short delay with little effort,” as the news release put it.,AmericasChild Survives After 7 Minutes Without Blood Flow to Brain During Surgery, US Cardiologist Reveals11 August, 16:41 GMT,Furthermore, members of that group had higher levels of glutamate in the synapses of the prefrontal cortex, leading the researchers to suggest that the accumulation of glutamate “makes further activation of the prefrontal cortex more costly,” and thus a mentally exhaustive workday makes cognitive control more difficult.,Unfortunately, there seems to be no fancy way to deal with this problem other than the tried and tested method that is probably as old as history itself.,“I would employ good old recipes: rest and sleep!” Pessiglione remarked. “There is good evidence that glutamate is eliminated from synapses during sleep.”。　　当地时间8月21日，美国总统特朗普抵达南卡罗来纳州，为上个月暴毙的共和党参议员林赛·格雷厄姆的妹妹达琳助选。特朗普在演讲时重申必须阻止伊朗发展核武器。

二 | 他还称伊朗非常渴望达成协议，但他不知道自己是否真想达成协议，因为在他看来，“霍尔木兹海峡现在是美国的领土，它就是美国的领土”。　　据美国阿克西奥斯新闻网站8月19日报道，两名美国官员称，美军已悄悄建立一条进出霍尔木兹海峡的航运通道，确保每天有“数百万桶”石油运出霍尔木兹海峡。　　美国东部时间8月21日下午，美国总统特朗普在马里兰州安德鲁斯联合基地准备搭乘“空军一号”专机时对媒体称，伊朗还没准备好达成一份“合适的协议”。特朗普是在被问及“对伊朗发动经济战是否意味着美国在该地区的军事选项已经受限”的提问时作出上述表态的。

三 | 他表示，这不意味着美国的军事选项已经受限，美国“只是在观察事态发展”。

四 | 他再次强调美国对霍尔木兹海峡相关区域“拥有绝对控制权”，并称其管控范围还进一步“延伸至陆上区域”。　　特朗普称，“伊朗很想达成协议，但在我看来，他们还没准备好达成一份合适的协议。”　　伊朗武装部队总参谋长阿卜杜拉希今天（8月22日）视察了一处地下国防工业生产基地。他表示，过去一年，伊朗国防工业在生产速度和质量上“取得了令人瞩目的进步”，在相关专业人员的努力下，“伊朗生产出性能更优、质量更高的装备，且产量远超以往”。　　据伊朗迈赫尔通讯社22日报道，伊朗国防部发言人礼萨·塔拉埃-尼克接受伊朗国家电视台采访时表示，过去一年来，伊朗武器和国防装备的产量翻了一番。　　塔拉埃-尼克说，在去年6月与美以持续12天的冲突结束后，伊朗的武器和国防装备产量整体翻了一番，部分战时优先列装的战略装备的产量甚至增长了三倍以上。这与美国和以色列领导人一度声称“伊朗国防生产将陷入停滞”的说法截然相反。

五 | 　　他还表示，为保守军事机密，部分装备系统暂未对外展示，但军队指挥官了解包括弹道导弹、巡航导弹、无人机及防空系统在内的生产与升级进度。　　在俄罗斯卫星通讯社8月19日发布的采访视频中，伊朗伊斯兰革命卫队总司令顾问穆罕默德·雷扎·纳格迪表示，这场战争表明美国和以色列比想象中“弱得多”。此前伊朗一直坚持防御性战略，敌人才敢一再发动攻击，或许伊朗应采取进攻策略，以实现对美国和以色列更高级别的威慑，迫使敌人撤退并剥夺其发动新攻击的勇气。（文章来源：每日经济新闻）。
