Palestinian death toll in West Bank surges as Israel pursues militants following Hamas rampage_我的网站

A |     JERUSALEM -- Deadly violence has been surging in the West Bank as the Israeli military pursues Palestinian militants in the aftermath of the Hamas attack from Gaza, with at least 90 Palestinians killed in the Israeli-occupied territory in the past two weeks, mainly in clashes with Israeli troops.The violence threatens to open another front in the 2-week-old war, and puts pressure on the internationally recognized Palestinian Authority, which administers parts of the West Bank and is deeply unpopular among Palestinians, in large part because it cooperates with Israel on security matters. The tally includes five Palestinians killed in separate incidents on Sunday, including two who died in an airstrike on a mosque in the volatile Jenin refugee camp that Israel said was being used by militants. Israel carried out an airstrike during a battle in another West Bank refugee camp last week, in which 13 Palestinians, including five minors, and a member of Israel's paramilitary Border Police were killed. Israel rarely uses air power in the occupied West Bank, even as it has bombarded Hamas-ruled Gaza since the militant group stormed across the border on Oct. 7. More than 1,400 people have been killed in Israel since the war began, mostly civilians killed in the initial Hamas assault. The Hamas-run Health Ministry in Gaza says over 4,300 Palestinians have been killed. The Palestinian Health Ministry in the West Bank says 90 Palestinians have been killed there since Oct. 7, a dramatic jump from 197, according to an Associated Press count, from the start of the year until the Hamas attack. In addition to the raids, Palestinians have been killed in violent anti-Israel protests and in some instances in attacks by Jewish settlers.Israel clamped down on the territory immediately after the Hamas assault, closing crossings and checkpoints between Palestinian towns. Israel says its forces have detained over 700 suspects in the West Bank, including 480 members of Hamas, since the start of hostilities.Israel’s resumption of aerial attacks — which in a July operation in Jenin reached a level of intensity not seen since the Palestinian uprising against Israel two decades ago — suggests a shift in military tactics.The military described the Al-Ansar Mosque in Jenin as a militant compound belonging to Hamas and Islamic Jihad, a smaller and more radical Palestinian militant group. It said the militants had carried out several attacks in recent months and were planning another imminent assault.The intensified violence follows more than a year of escalating raids and arrests in the West Bank and deadly Palestinian attacks on Israelis.Israel captured the West Bank, along with Gaza and east Jerusalem, in the 1967 war. The Palestinians want all three territories for a future state. Over 500,000 Israelis live in settlements across the West Bank that most of the international community considers illegal, while the territory's more than 2.5 million Palestinians live under Israeli military rule.The Palestinians view the settlements as the greatest obstacle to resolving the conflict with Israel. The last serious and substantive peace talks broke down over a decade ago. Settler violence against Palestinians has also intensified since the Hamas attack. At least five Palestinians have been killed by settlers, according to Palestinian authorities, and rights groups say settlers have torched cars and attacked several small Bedouin communities, forcing them to evacuate to other areas.The West Bank Protection Consortium, a coalition of non-governmental organizations and donor countries, including the European Union, says at least 470 Palestinians have been forcibly displaced in the West Bank due to settler violence since Oct. 7. That's in addition to over 1,100 displaced since 2022. ___Associated Press writer Joseph Krauss contributed to this report.。    

原标题:今年中国已有7种高端钢材实现全新突破,面向新能源汽车、人形机器人等新兴赛道IT之家 8 月 24 日消息,据央视新闻客户端 8 月 22 日报道,我国钢铁产量连续多年位居世界首位。今年以来,钢铁企业依托全国重点实验室,聚焦高端特种钢材持续发力,不断实现核心技术突破,一大批高端钢材实现了自主量产。钢材如何做到强度过硬,还能抵御海水腐蚀?在河北唐山的钢铁实验室,记者找到了答案。钢材加工过程中会产生易导致材料脆化的碳化物,科研人员通过调控钢材原子结构,将碳化物有效包裹。研究人员给记者算了一笔账,一台海上风电机要用钢数百吨,换上这种高性能钢,钢板可以做得更薄,合金用量也大幅减少。如今,不只在海上,我国已经搭建起覆盖深海装备、舰船制造、航空航天等多场景的高端钢材自主研发量产体系,从材料配方、轧制工艺到批量生产实现全链条自主可控。

IT之家从报道中获悉,这款我国自主研发的“蝉翼钢”厚度仅有 0.07 毫米,具备高强度、高延展性,达到全球精制钢顶级水平。目前,这款钢材已广泛应用在集成电路基板、5G 基站信号接收器等多个领域。而在航空航天领域,新研发的低膨胀特种钢材已经投入大飞机复合材料成型模具生产。数据显示,今年以来,已有 7 种高端钢材实现全新突破,面向新能源汽车、人形机器人、储能装备等新兴赛道,多款专用电工钢、高强结构钢实现批量下线,为新兴装备核心部件提供材料保障。目前,我国已有 3 家钢铁企业入选全球“灯塔工厂”,累计培育 36 家卓越级钢铁智能工厂、2 家领航级智能工厂。

延伸阅读据介绍,“蝉翼钢”又称“5G 钢”,由首钢京唐钢铁联合有限责任公司研发,其最薄厚度仅 0.07 毫米,相当于一根头发丝的直径,比普通 A4 纸还要薄,且具备高强度、高延展性,可轻松弯折对折。除文中提到的集成电路基板、5G 基站信号接收器外,该钢材还广泛应用于手机内部精密弹片、信号发射滤波器、新能源电池连接片以及高端食品的密封镀锡包装材料等领域。此外,“蝉翼钢”此前还曾制成北京 2022 年冬奥会主题明信片和党的二十大《长城颂》明信片,登上国际舞台。在高端电工钢领域,0.1 毫米级无取向电工钢的铁损指标已处于全球第一梯队,该产品覆盖了全球前十家领军车企,国内每 3 辆新能源汽车中就有 1 辆搭载其制成的电机铁芯。
