Mental strength key for Beijing medal: Ski jumping world champion******

WARSAW, Oct. 27 (Xinhua) -- Polish ski jumping world champion Piotr Zyla ensured that he will prepare well for the Winter Olympics and "mental strength will be a key factor to achieve success" in Beijing.

Zyla stood on the highest podium at the FIS Nordic World Ski Championships 2021 in Oberstdorf, Germany. In the new season, the main target for him is to take his first Olympic medal.

"I don't put extra pressure on myself. I try not to focus on the games. For me, the whole winter is important, although the Olympics are indeed the target event and we are to be in top shape there," the ski jumper said in a Wednesday interview for local media. "I will be ready, the mental strength is the most important."

The Poland team hasn't jumped yet on the Olympic hills in China.

"There will definitely be an additional thrill because it's an unexplored object for us. But the hill really doesn't matter. If you are in shape, you jump far. The jump technique doesn't change," Zyla claimed.

The six-time world championships medalist hopes that he will keep momentum by achieving good results until the Winter Olympics.

"You have to keep going all the time. Whenever you stay at the same level, it feels like you've taken a step back. That is why you have to take the good results all the time and push the limits of your abilities," the 34-year-old concluded. Enditem

US life expectancy saw huge drop in 2020 due to COVID******

US life expectancy dropped by 1.8 years in 2020, final official figures showed on Wednesday, the steepest drop in more than 75 years driven in large part by the COVID-19 pandemic.。

Life expectancy at birth was 77.0 years for the total US population last year, down from 78.8 years in 2019, according to the Centers for Disease Control and Prevention.。

Among men it was 74.2 years, while for women the figure was 79.9 years.。

Overall, COVID-19 was the third-leading cause of death, accounting for 350,000 fatalities, just over a tenth of all registered deaths, said a CDC report, which finalized preliminary findings from July.。

Some other causes of death also increased, possibly linked to difficulties accessing health care brought about by the pandemic. For the first time, diabetes deaths topped 100,000, while accidental/unintentional injury deaths topped 200,000 – also a first.。

The latest data comes after the US Census Bureau released a statement that said the pandemic drove population growth to its lowest rate in history, due in part to deaths from the virus and a drop in immigration.。

For the 12 months ended July 1, the population of the United States grew by 392,665 or just 0.1 percent, "the lowest rate since the nation's founding," the agency said in a statement.。

"Population growth has been slowing for years because of lower birth rates and decreasing net international migration, all while mortality rates are rising due to the aging of the nation's population," said Kristie Wilder, a demographer in the Population Division at the Census Bureau.。

"Now, with the impact of the COVID-19 pandemic, this combination has resulted in a historically slow pace of growth."

Even with the decline in immigration over the latest 12-month period, the net international migration of 244,622 for the first time ever exceeded the "natural increase" of US births over deaths – 148,043 in 2020 – the agency said.。

Due to delays in crunching the numbers caused by the pandemic, the Census Bureau's latest population report used blended data incorporating estimates from the once-a-decade 2020 census with other sources, including birth, death and migration records.。

Between 2020 and 2021, 33 states saw population increases and 17 states and the District of Columbia lost population, 11 of which had losses of over 10,000 people, the agency said, calling it "a historically large" number of states losing residents.。

A separate analysis showed Texas had the biggest population increase at 1.1 percent, mostly due to domestic migration to the state and rising net birth rates.。

New York showed the biggest decline, falling 1.6 percent in the year, mostly due to domestic migration out of the state, the agency said.。

全新雷蛇猎魂光蛛 V2 上手:可以忽略的超低延迟,也变得更安静了******摘要



今年二月份的时候,雷蛇正式推出了猎魂光蛛 V2 模拟光轴键盘,在这套轴体的支持下,它能够提供非常精确的游戏反馈。时隔差不多半年多之后,前段时间雷蛇又带来了全新雷蛇猎魂光蛛 V2,新品在轴体、键帽、回报率以及静音效果等很多方面都做了升级。

如果你熟悉雷蛇猎魂光蛛系列,那么对于全新雷蛇猎魂光蛛 V2 应该也不会感到陌生。大的外观方面,它依旧延续了家族式设计风格。个人而言,黑色键盘的好处不只是视觉效果上比较容易和其它桌面设备进行搭配,更重要的一点是长时间使用更方便保持清洁感。

说到长期使用过程中的键盘清洁性,这代雷蛇猎魂光蛛 V2 好的一点,是它同样采用了双色注塑 PBT 键帽,这种键帽的好处大家也都知道,相比 ABS 材质键帽,坚固性以及耐磨性都要来得更好一些。此外,你也无需担心会出现按键表面字符褪色的情况。

猎魂光蛛系列很有标志性地方,或者说能让你一眼就可以认出的点,其实就是位于数字键区上方的多功能数字旋钮和 4 枚多媒体按键,借助这几枚按键可以很方便地控制音乐播放、暂停以及调节音量。无聊的时候,可以用那枚多功能数字旋钮来打发时间。

细节处理以及选材用料也很讲究。全新猎魂光蛛 V2 多功能数字旋钮外围做了密集菱形凸起,能一定程度上增加表面摩擦,以免因为手指出汗影响到操控准确性。材质则为铝制框架,并且周身均做了亮面切边处理,有着不错坚固性的同时也更加精致。

这代猎魂光蛛 V2 系列包含标准版和竞技版两个版本,我们手里拿到的标准版为固定线缆设计,竞技版则为可拔插 USB-C 线缆。这种编织材质线缆实际用起来比较省心,几乎不会出现打结的问题,也不会因为环境温度逐渐开始降低,而显得过于硬邦邦。

更有吸引力的地方,当然还是操控性有了比较明显的升级。在全新猎魂光蛛 V2 上,雷蛇为其用到了第二代光轴,提供线性光轴和段落光轴两种选项。由于光轴采用红外线光束激活轴体信号,能让键盘将延迟控制得更低,并且按键耐用性也更好。

官方称,配合雷蛇自家 Razer HyperPolling 8000Hz 超快轮询技术,这代产品能将延迟压低到 0.2 毫秒,而大多数常规机械键盘的延迟都在 2 毫秒以上,在玩一些要求极致操作的游戏时,能给出更及时的反馈。实际用起来,线性光轴和段落光轴之间的区别主要表现在敲击感上。


其它之前很多雷蛇键盘都有的一些功能,全新猎魂光蛛 V2 也都没有落下。比如,它同样搭载了 Razer Chroma 幻彩 RGB 灯光系统,可以根据自己的喜好在 Synapse 雷云 3 软件中自定义设置;最多支持 5 个板载内存配置文件,方便下次使用;依旧具备 N 键无冲能力。

和之前一样,全新猎魂光蛛 V2 当然也匹配有独立腕托,腕托表面为皮革材质,实际摸上去手感比较柔软,能为手腕提供很好支撑。腕托和键盘之间还是大家熟悉的磁吸连接,不过这次雷蛇没有在键盘下端设置金属触点,腕托本身也没有配备灯带装饰。

全新雷蛇猎魂光蛛 V2 底部一共做了 6 个橡胶材质垫脚,即便你习惯像我这样直接将键盘放到桌面上使用,也不必担心会出现打滑的问题。此外,这款键盘也做了两档不同角度的支脚,根据自己认为最舒适的角度调节就好。

总的来说,这代猎魂光蛛 V2 变得更好用了。它的好用可以从两个方面来看,一方面是性能更强,0.2 毫秒的超低延迟控制,是很多其它同价位段竞品所无法提供的,能带来实实在在的操控性提升;另外一方面则是使用感受,安静且舒服的敲击感,用起来非常舒服。

最后,线性光轴和段落光轴版本猎魂光蛛 V2 价格一样,均为 1599 元,至于如何选择,就看个人喜好了。另外, 如果你更倾向于能带着出差的键盘,建议考虑下全新猎魂光蛛 V2 竞技版,除了线缆支持拆卸,个头相对标准版也要来得更小一些。
