Beijing 2022 conducts water******

BEIJING, Dec. 3 (Xinhua) -- Snow making for Alpine skiing events at the 2022 Winter Olympics is underway in Beijing's Yanqing district and is expected to be completed by mid-January.。

The water needed for snow making at the Yanqing competition zone, where Alpine skiing events will be staged, will account for just 1.6 percent of water used in the area, according to the Beijing Water Authority.。

In the Zhangjiakou competition zone, where freestyle skiing, snowboarding, cross-country skiing, biathlon and ski jumping events will take place, the water demand during the Games will account for 9.8 percent of the total current water consumption in Zhangjiakou's Chongli district.。

"The man-made snow will not affect the local water usage," said Zhao Weidong, a spokesman for the Beijing 2022 organizing committee (BOCOG).。

Competition snow requires a higher density than recreational snow in order to meet the requirements of the FIS, professional skiing's governing body, and to ensure conditions are consistent for each competitor.。

Man-made snow was first used at the 1980 Lake Placid Olympic Winter Games. Around 90 percent of snow used at the Alpine skiing venue for the PyeongChang 2018 Winter Olympics was artificial, while man-made snow was also a feature of Vancouver 2010 and Sochi 2014.。

In line with Beijing 2022's goal of hosting a sustainable and eco-friendly Games, a series of water-conserving techniques have been adopted in snowmaking, according to BOCOG.。

"For Alpine skiing, natural snowfall is incapable of providing sufficient competition snow. Even if the natural snow depth reaches 3m, it can only be compressed into a snow layer of 30cm to 40cm in depth, still far off the requirement for Olympic tracks, which is also one of the reasons why man-made snow has been widely used in snow sports in Winter Olympics worldwide," said Lyu Hongyou, an operations manager at Yanqing.。

Snow-making is not an irreversible consumption of water resources; instead, the snow-melt water can be recycled into reservoirs. Three reservoirs with a total maximum water storage of 160,000 cubic meters can collect the snow-melt and rainwater through conduits in the Yanqing competition zone and pump up the water for snowmaking in the venues, forming an internal recycle of water resources, said Sun Xianghui, an engineer from Beijing Beikong Jing'ao Construction Corporation.。

In the south of Yanqing, a sewage treatment station has been established to process the sanitary sewage from the competition zone into reclaimed water for plant-watering and toilet use, Sun added.。

During the snowmaking process for Beijing 2022 venues, the collected natural precipitation and the overland runoff will be primarily used, and an intelligent system will help decide the timing for snowmaking based on the weather conditions, also in an endeavor to further save water resources and improve efficiency, Zhao said.

终于知道奥特曼怎么生孩子了!这么独特?网友表示我不相信******

原标题:终于知道奥特曼怎么生孩子了!这么独特?网友表示我不相信

观众朋友们大家好呀,欢迎收看本期的动漫三分钟,我是你们的豪哥,豪哥从小的时候就非常好奇一个问题,就是奥特曼是怎么生孩子的,因为小泰罗的出现,让不少人都知道了,原来奥特曼还是小孩子版的。

有的朋友表示,应该是先变回人类姿态,等生产了之后在变回奥特曼。这个倒是有一些依据,毕竟圆谷的设定是奥特曼是和人类非常相似的宇宙人,因为等离子火花的原因,导致他们变成了奥特曼,这就不排除能够变回人类的情况!

所以根据这个很多朋友们推测出来,赛罗奥特曼就是赛文的人间体诸星团和尤里安奴两人所生,在剧中多次曝光了二人的关系,很明显就是情侣嘛。第二种就是说就是正常的方式,因为最早的奥特曼毕竟是由类似人类的宇宙人变成的,那就一定会有羞耻感和自尊心。如果奥特曼是不穿衣服的,那不太现实!

所以奥特曼应该还是有衣服的,那样的话怎么生孩子的就不需要考虑了,很符合宇宙法则大自然规律!不过在圆谷的官方设定中,对于奥特曼的诞生是这样解释的,在泰罗奥特曼中我们可以看到,泰罗的诞生是由其他的奥特兄弟,加上奥特之母们用特殊的能量制造的!可以说奥特曼就是光能量的集合体,不过很多网友表示不信,毕竟圆谷是著名的吃设定,也就那么回事吧!如果是光的集合体,那么赛罗,泰罗之类的奥特曼是怎么像自己的父亲的呢?难道是奥特之父和赛文把自己身体里一部分的光分离了出去放到了新的奥特曼里所以才这么像的吗?不知道小伙伴们有没有考虑过这个问题呢?如果你们有很厉害的想法,可以跟豪哥一起交流一下哦~

Barcelona eyeing River Plate forward Alvarez******

BUENOS AIRES, Dec. 10 (Xinhua) -- Barcelona have joined the race to sign highly rated River Plate forward Julian Alvarez, according to media reports in Argentina.。

The Catalan giants have sent scouts to observe Alvarez in Argentina's Primera Division and could make a move for the 21-year-old in the January transfer window, the Ole news outlet said on Friday.。

It added that the Blaugrana's interest has been heightened by a hamstring injury to Memphis Depay and uncertainty surrounding the future of Sergio Aguero due to heart problems.。

Capped five times for Argentina's national team, Alvarez is the Primera Division's top scorer this season with 17 goals in 20 matches.。

His performances have reportedly also caught the attention of Juventus, Sevilla, Inter Milan, Bayer Leverkusen, Milan and Fiorentina.。

Alvarez has a 20 million-euro buyout clause in his River Plate contract, which expires next December. However, it is believed the Buenos Aires club could demand twice that figure given the attacker's recent form and growing interest from European suitors. Enditem。

Rio Open set for February return******

RIO DE JANEIRO, Oct. 28 (Xinhua) -- The Rio Open, South America's only ATP 500 event, will return in 2022 after being canceled this year because of COVID-19, organizers said on Thursday.

The clay-court tournament will be played at the Jockey Club Brasileiro from February 12 to 20 in Rio de Janeiro's southern neighborhood of Gavea.

"We missed you a lot, but we're back. The return of the Rio Open is a great gift for the city of Rio de Janeiro," tournament director Marcia Casz said in a statement.

"The successful vaccination program gave us a desire to be back together again... safely, of course. We are preparing a Rio Open that will be the best of all," she added.

Previous Rio Open winners include Rafael Nadal, David Ferrer, Dominic Thiem and Diego Schwartzman.

The last edition in 2020 was won by Chile's Cristian Garin, who beat Gianluca Mager of Italy in the final 7-6, 7-5. Enditem
