Nicholas Burns approved as China envoy by US Senate******

In this file photo taken on October 20, Nicholas Burns testifies before the Senate Foreign Relations Committee confirmation hearing on his nomination to be Ambassador to China on Capitol Hill in Washington, DC.。

The US Senate on Thursday confirmed veteran diplomat Nicholas Burns as ambassador to Beijing, filling a position vacant for more than a year.。

The Senate reached the key 50-vote threshold to approve Burns in an ongoing confirmation that took place after Senator Marco Rubio lifted objections. The final vote was 75-18.。

President Joe Biden nominated Burns in August, more than half a year into his term.。

"If you're looking for a bipartisan person to put in a position, this is your guy," said Jim Risch, the top Republican on the Senate Foreign Relations Committee.。

"He's done an outstanding job, has an outstanding reputation amongst the cadre of ambassadors."

The 65-year-old served as the State Department's No. 3 official under former President George W. Bush and as the spokesperson of the department under Bill Clinton.。

Burns retired from the Foreign Service in 2008 and became a professor at Harvard University.。

Trump's ambassador to China, Terry Branstad, resigned in October 2020 to help the Republican president's campaign against Biden.。

引汉济渭秦岭输水隧洞全线贯通 关中人年内将喝上汉江水******

引汉济渭秦岭输水隧洞全线贯通。

西部网讯(记者 凌旎 马晴茹 杜鹏 宋洋)今天(2月22日)11时17分,陕西安康市宁陕县四亩地镇引汉济渭秦岭输水隧洞4号支洞内传来好消息。随着TBM(隧道硬岩掘进机)刀盘破岩而出,引汉济渭秦岭输水隧洞实现全线贯通,这标志着引汉济渭工程关键控制性工程取得重大胜利,年内可先期向西安供水,汉水穿越秦岭润泽秦川大地的美好愿景指日可待。

引汉济渭秦岭输水隧洞全线贯通。

陕西版“南水北调” 2030年将实现配水15亿立方米

长期以来,缺水问题制约着关中、陕北的经济社会发展。因此,陕西启动了省内南水北调工程——引汉济渭工程,统筹陕西三大区域,联通长江与黄河两大水系,横穿秦岭屏障,将汉江水引入关中平原,破解陕西水资源分布不均的问题。

该工程是《渭河流域重点治理规划》中的水资源配置骨干项目、《关中——天水经济区规划》中的重大基础设施建设项目,也是国家“十三五”加快推进的172项重大水利工程之一,建成后多年平均调水规模可达15亿立方米,惠及1411万人,支撑全省1.1万亿元的国内生产总值。

引汉济渭工程分为调水工程和输配水工程两大部分,通过“一次立项、分期配水”的建设方案,将逐步实现2025年配水10亿立方米、2030年配水15亿立方米目标,以此解决关中、陕北缺水问题。

待全部完工后,引汉济渭工程会将陕南丰富的水资源调到关中地区,输送至渭河两岸的西安、咸阳、渭南、杨凌4个重点城市,西咸新区5座新城,周至、鄠邑、长安等11个中小城市及渭北工业园区等共计21个受水对象,可支撑全省1.1万亿元国内生产总值,受益人口达1411万。

首次尝试从底部横穿秦岭 施工难度世界罕见

秦岭输水隧洞是引汉济渭工程的关键控制性工程,也是人类从底部横穿秦岭的首次尝试。隧洞全长98.3千米,最大埋深2012米,设计流量70立方米每秒,纵坡1/2500,穿越地区地质条件极其复杂,众多院士、专家评价为“综合施工难度世界罕见”。

据统计,秦岭输水隧洞累计发生岩爆4000余次,其中中等等级以上3000余次,最大震级1.6级。针对超长施工通风难题,引汉济渭工程创立了完整的超长隧洞TBM法和钻爆法新的施工通风成套技术体系,创造了钻爆法无轨运输施工通风距离7.2千米、TBM法独头掘进施工通风距离16.5千米的世界纪录。

受地质地形等条件限制,秦岭输水隧洞采取钻爆法和TBM联合施工,其中钻爆法施工63.3千米,TBM施工35千米。尤其是TBM施工段,先后遭遇强岩爆、超强岩爆、断层塌方、突涌水、高温高湿、有害气体等地质灾害。

  除了女子单人赛之外,王沛宣还将在2月10日参加团体接力比赛。团体接力比赛中,终点线上方设有接力触板,运动员通过终点前,需要坐起拍击触板,从而开启起点处的出发门,由此完成团队接力。


Former Pentagon chief sues to publish material in memoir******

Former US Defense Secretary Mark Esper claims in a lawsuit against the Defense Department that material is being improperly withheld from his use as he seeks to publish an "unvarnished and candid memoir" of his time in President Donald Trump's Cabinet.。

The lawsuit, which was filed on Sunday in the US District Court in Washington, describes the memoir, "A Sacred Oath," as an account of Esper's tenure as Army Secretary from 2017 to 2019 and his 18 months as Defense Secretary, which ended when Trump fired him in a tweet just days after the president lost his- reelection bid.。

The period in which Esper was Pentagon chief was "an unprecedented time of civil unrest, public health crises, growing threats abroad, Pentagon transformation, and a White House seemingly bent on circumventing the Constitution," the lawsuit says.。

Esper and Trump were sharply divided over the use of the military during civil unrest in June 2020 following the killing of George Floyd.。

Other issues led the president to believe Esper was not sufficiently loyal while Esper believed he was trying to keep the department apolitical.。

Firing a defense secretary after an election loss was unprecedented.。

But the opening allowed Trump to install loyalists in top Pentagon positions as he continued to dispute his election loss.。

The lawsuit contends that "significant text" in the memoir, scheduled for publication by William Morrow in May, is being improperly held under the guise of classification and that Esper maintains it contains no classified information. The suit notes that Esper is restricted by his secrecy agreements from authorizing publication without Pentagon approval, or face possible civil and criminal liability.。

The lawsuit quotes from a letter Esper sent to Defense Secretary Lloyd Austin criticizing the review process. He wrote that he had been asked not to quote Trump and others in meetings, not to describe conversations he had with Trump, and not to use certain verbs or nouns when describing historical events.。
