Cultural China: Modern models of sci******

BEIJING, Nov. 14 (Xinhua) -- If there is a single theme throughout the history of science and technology in China, it is self-improvement.

An ancient Chinese saying from "Zhou Yi," or "The Book of Changes," written over 2,000 years ago, goes: One should never stop striving for self-improvement and hold the world with virtue.

Chinese scientists Gu Songfen and Wang Dazhong, who won China's top science award this year, are modern models of the self-taught man.

Born in 1930, Gu is an aircraft designer at the Aviation Industry Corporation of China, Ltd., the country's leading aircraft maker. At the age of 21, he joined China's aviation industry when it was in its infancy.

In 1956, China's first aircraft design office was established in Shenyang, Liaoning Province, and its first task was to develop the country's first homegrown jet aircraft. Gu was appointed head of the aerodynamics team.

Aerodynamics is the "soul" of aircraft design. The study of the way objects move through the air ensures an aircraft can fly efficiently and carry weapons as well as guaranteeing the stable and safe operation of the engine.

However, in the 1950s, China had no aviation experience, equipment or wind tunnels. Gu decided to teach himself.

After finding foreign texts at the library at Beihang University in Beijing, Gu headed to the capital, borrowed a bike and visited the library every day.

He read a range of books and transcribed all the information he could get his hands on.

Based on that information, Gu came up with an aerodynamic design system and on July 26, 1958, after two years of development, his team celebrated the maiden flight of China's first training jet.

Gu went on to work on the development of the J-8, the country's first supersonic jet fighter, which made its first test flight in 1969 but encountered serious vibration problems during subsequent flights.

To identify the cause of the vibrations, Gu volunteered to observe the aircraft in flight himself.

"We didn't have a camera, so it could only be done by a person," he said. He glued skeins of knitting wool to the J-8's rear fuselage and tail wing to observe their flow during flight.

To get a clear view of the way the wool was disturbed, he required two planes to fly just five meters apart, a great risk for him and his pilot. After several flights, he finally found and fixed the problem.

In 1980, he was in charge of the design of J-8-II, which was required to perform at a much higher level than previous aircraft. In four years, Gu's team achieved the maiden flight of the J-8-II, laying the cornerstone for China's supersonic aircraft design.

Gu's endless curiosity drove his spirit of lifelong learning. He continued his scientific inquiries, translated foreign books, talked with young scholars, and even learned Russian, Japanese and German late in life.

Like Gu, Wang Dazhong's life also reflects a belief in self-improvement. Born in 1935, Wang has dedicated himself to the research and development of advanced nuclear energy technologies.

An internationally reputed nuclear scientist, Wang is former president of China's top-ranking Tsinghua University, which also has self-improvement as its motto.

Over the past six decades, Wang has led his team in blazing a trail, turning China from a latecomer to a leader in advanced nuclear energy technologies.

Wang and his colleagues built from scratch China's first self-developed shielded test reactor at a mountain village in the outskirts of Beijing.

The average age of the design group was under 23, and no one had studied abroad or seen a real nuclear reactor. They started by building engineering models and made designs and calculations with hand-cranked machines.

China's first self-developed nuclear reactor was completed in 1964 after six years of development.

After Three Mile Island in the United States in 1979 and Chernobyl in the Soviet Union in 1986, Wang set his eyes on inherent safety and concentrated research into a high-temperature gas-cooled reactor (HTGR). Although the development of nuclear energy was at a low ebb globally, Wang's resolution to continue in the field was unshaken.

In 1986, Wang and his team again started from scratch to develop a 10MW HTGR and it reached full-power operation in 2003. Its completion ushered in a new generation of nuclear energy systems that effectively eliminate the possibility of reactor core meltdown.

From there, Wang and his team spent years promoting the transition from experimental reactors to industrial-scale prototype reactors. Their achievements helped China independently master modular HTGR technology, and create a comprehensive development chain, from basic scientific research to commercial manufacture.

Likening scientific research to climbing mountains, Wang said the road to success is full of difficulties and risks and requires the ability to analyze problems, the courage to explore uncharted territory, and resilience in the face of failure.

The lives of these two scientists illustrate the ancient saying and echo the call by Chinese leaders to uphold the central role of innovation in China's modernization drive and to be self-reliant in science and technology as a strategic underpinning for national development. Enditem

历时11年!23层的西安“最牛民房”宣布动工拆卸******  \

经历11年,西安市西寨北山大门口村的23层“最强民房”正式开始拆除,而它周边的别的民房早已所有拆除结束。

  2010年华商报就曾报导了这幢23容积率的“最强民房”,由于这幢楼沒有一切审核办理手续,由北山大门口村13户群众拼接农村宅基地集资款修建的。据统计,这幢楼内一共有70余户,占地面积8000余平方米,屋子总面积从八九十平米到170平米,在其中8层下列是两梯四户,8层之上各层基本上是三户,23层楼房顶层为复式结构。

  \

11月11日早上,华商报记者赶到西安电子器件西街与电子器件三路交叉路口的北山口村,当场除开三幢23层的民房外,其他地区早已完成了拆除。屋顶有两部挖机已经工作,也有职工洒水除尘,现阶段已拆除一层多。

  附近水果店的老总告知记者,这幢楼是11月8日逐渐拆除的,那时候挖机被大吊车运到屋顶。住在周边的胡先生说,北山大门口村规划区是2021年3月中下旬逐渐拆除的,一个多月后,周边就只剩这幢23楼高沒有拆除了,“之后停产了好长时间,直至前段时间才正式开始拆除。”。

  \

记者联络到一名曾住在楼里的群众,她们家房子总面积为170平米。2021年3月底,因听闻动迁,她赶出了那边,“由于被确认为违章建筑,因此此次动迁,楼内居民只获得了每平米4000多元化的赔付,3万余元的室内装修赔付,且沒有衔接费。”。

  \

接着,记者前去雁塔区沙泘坨规划区(北山大门口村)城市发展新项目总指挥部,大门口贴到的《有关拆除违法建设的协同通知》表明,“未依规获得工程建设施工许可证,及其未依照施工许可证要求开展基本建设的房屋建筑,建筑物,临时性房屋建筑等工程建设,均属违法建设……依规拆除的违法建设不予以赔偿……2021年10月17日现场踏勘评定,雁塔区北山大门口村安装地区内集体用地违法建设房屋建筑行的居(租)居民及开展生产运营活動的经营者,务必三日内搬出……”下边有雁塔区城市管理局,雁塔区城棚户区改造事务管理核心等企业图章,時间为“2021年10月20日”。

Ukraine celebrates Day of Unity to show consolidation amid crisis******

AFP

People carry a giant Ukraine's national flag at a stadium to mark a "Day of Unity" in Kiev on February 16, 2022.

Ukraine on Wednesday celebrated the national Day of Unity to consolidate people amid the crisis in the country.

In a televised address to the nation, Ukrainian President Volodymyr Zelensky said that Ukrainians are different, but they all are united by the desire to live in peace, happiness and with their loved ones.

"We are all united by one desire: to live in peace, happily, as one family, with children, with parents. And we have every right to all this. Because we are at home, we are in Ukraine," Zelensky said.

Meanwhile, Ukrainian Prime Minister Denys Shmyhal said that Ukrainians mark the Day of Unity to show the "friends and enemies" that Ukraine is united even in hard times.

"Ukrainians have rejected their differences and are uniting in the face of possible threats. For a successful future. We know how to do it, and our unity is our best weapon," Shmyhal wrote on his official Telegram channel.

Within the framework of the celebrations, Ukrainian enthusiasts unfolded a 200-meter-long national flag at the Olympic stadium in Kiev.

The blue-and-yellow flags were waved on government buildings, private houses and cars across the country to show the unity of the people.

Children in many schools and kindergartens were asked to wear vyshyvanka, traditional Ukrainian ethnic clothing decorated with embroidery patterns.

In addition, the Ukrainian Infrastructure Ministry launched the Train of Unity from Ukraine's western city of Rakhiv to the eastern city of Mariupol that carried the Ukrainian flag through different regions across the country.

The ambassadors of the European Union countries laid flowers on the Wall of Remembrance in Kiev to mark the Day of Unity, showing their support for Ukraine, and paying tribute to all who have fallen in the conflict in eastern Ukraine since 2014.

Some Western media had claimed that Russia could invade Ukraine on February 16. Moscow has repeatedly denied any plans to invade Ukraine.

Earlier on Wednesday, Ukrainian Defense Minister Olexiy Reznikov said that the situation on the Ukrainian borders remains stable.

媒体谈欧莱雅面膜差价事情:商家充斥着套路的广告营销当休矣******

  近日,有消费者举报,巴黎欧莱雅曾在官博宣传策划企业商品安瓶补水面膜在李佳琦直播间的特惠为“全年度较大幅度”,总共50片的补水面膜市场价429元。但11月1日至3日,巴黎欧莱雅官方网淘宝直播不断释放几万元张“满999元-200元”优惠劵,促使相同补水面膜用券后最低价位为257.7元。接着,该事情不断发醇。11月18日,巴黎欧莱雅官博公布有关表明,针对本次巴黎欧莱雅安瓶补水面膜“双十一”营销体制因过度繁重繁杂而给消费者产生的困惑,表明深深地的歉疚。

  在每一年一度的“双十一”大促中,每个电子商务平台级经营人莫不用尽各种办法发布各种各样促销活动。在其中,根据头顶部主播带货早已变成许多彩妆品牌的关键促销手段。这种头部主播在卖货时通常可以得出更特惠的价钱,让消费者享有到大量性价比高。无论是什么类型的促销活动,假如招数多过真心实意,就很有可能涉嫌公布虚假广告。本次薇女坊“车翻”便是不错的例子。

  “全年度较大幅度”的营销推广术语早已涉嫌违背《广告法》有关广告宣传內容不可应用“国家级别”“最高级别”“最好”等極限术语的要求。假如该促销活动得出的价钱的确是年度最低价位,倒也无可非议。殊不知,在直播房间声称是“全年度较大幅度”,后又以别的促销手段给到更低的价钱,这对在直播房间选购的消费者不合理。

  店家的“招数营销推广”早已涉嫌多种多样违反规定,除应用極限广告词语外,还涉嫌虚假广告。依据《广告法》,广告宣传以虚报或是让人误会的內容蒙骗、欺诈消费者的,组成虚假广告。产品的特性、作用、原产地、主要用途、品质、规格型号、成份、价钱、市场销售情况、曾获荣耀等信息内容与具体情况不符合,对选购方式有实质危害的,即归属于虚假广告。公布虚假广告的,可处推广费用5倍之上10倍下列处罚,推广费用没法确定或是显著稍低的,处100多万元200元下列处罚,可以注销企业营业执照。

  除此之外,针对这类虚假广告,消费者还有权利规定经营人担负“退一赔三”的承担责任。据报道,2019年11月,在薇女坊(我国)有限责任公司因编造应用产品实际效果,被重庆市场管理管理处处罚20万余元。薇女坊再度在广告推广层面摔跟头,体现了其轻视消费者利益的一面,理应担负对应法律依据。

  互联网技术社会发展,电子商务中间的市场竞争日趋猛烈。为了更好地吸引住消费者,牟取大量市场占有率,店家莫不用尽各种办法发布各种各样促销活动。但是,再深的销售招数,再繁杂的营销策略,用心的消费者都是会发觉疏漏,可以较为出不一样阶段,不一样服务平台上下的价钱好坏。这警告经营人,不必把思绪都用在设计方案转让人目不暇接的优惠促销上,反而是要取出真心实意和诚心,不然总有一天会“车翻”。
