人体如何面对世界上最长的19个小时的飞行时间?

Regular nonstop flights between the east coast of Australia and London or New York could soon become a reality.

澳大利亚东海岸与伦敦或纽约之间的定期直飞航班可能很快就会成为现实。

In preparation, Australian airline Qantas has announced three test flights, with 40 people traveling directly from London or New York to Sydney, to see how the human body copes with 19 solid hours of air travel.

为了做好准备，澳大利亚航空公司澳航(Qantas)宣布了三次试飞，40人直接从伦敦或纽约飞往悉尼，以观察人体如何应对长达19个小时的空中旅行。

Qantas previously announced its goal of operating direct flights between London, New York, and three Australian cities -- Sydney, Brisbane and Melbourne -- by 2023.

澳航此前宣布，其目标是到2023年开通伦敦、纽约、悉尼、布里斯班和墨尔本之间的直飞航班。

The test flights scheduled for October, November and December will move the airline closer to that target and enable Qantas, alongside medical experts, to test the health and wellbeing impacts on passengers and crew.

定于10月、11月和12月进行的试飞，将使澳航更接近这一目标，并使澳航能够与医学专家一道，测试对乘客和机组人员健康和幸福感的影响。

There's no layovers, no extra journeys through customs and no transfer stress, he points out. "You can plan it so you fly over night, and you could arrive to actually have a productive day the next day as well," says Fehrm. "It's going to be businesspeople that fly this way."

他指出，这里没有中途停留，没有额外的通关旅程，也没有中转压力。Fehrm说:“你可以计划一下，这样你就可以在晚上飞过去，然后在第二天到达，实际上这一天你会有高效率。”“这将是商务人士的飞行方式。

If the 19-hour flight becomes a reality, it's likely to cost travelers more. "It's cheaper for the airline to do two separate flights," Fehrm says. "But some people are prepared to pay the extra price of that ticket."

如果这19个小时的飞行成为现实，旅客的花费可能会更高。Fehrm说:“对航空公司来说，分两次飞行更便宜。”“但有些人愿意支付额外的票价。

Before the trials begin later this year, three Boeing 787-9 Dreamliners, fresh off the production line, will be flown from Boeing's factory in Seattle to either London or New York.

在今年晚些时候开始试验之前，三架刚刚下线的波音787-9梦幻客机将从位于西雅图的波音工厂飞往伦敦或纽约。

After the test flights -- two from New York, one from London -- the new planes will enter commercial service. Most of the people on board the test flights will be Qantas employees, so seats won't be available for purchase.

试飞结束后——两架来自纽约，一架来自伦敦——新飞机将开始商业服务。测试航班上的大多数乘客都是澳航的员工，因此无法购买座位。

Researchers from Sydney University's Charles Perkins Centre, Monash University and the Alertness Safety and Productivity Cooperative Research Centre -- a scientific program backed by the Australian government -- will examine the impact of the long flight on those on board.

来自悉尼大学查尔斯·帕金斯中心、莫纳什大学和警惕性、安全和生产力合作研究中心的研究人员将研究长途飞行对机上人员的影响。警惕性、安全和生产力合作研究中心是一个由澳大利亚政府支持的科学项目。

Passengers in the main cabin will wear monitoring devices, and experts from the Charles Perkins Centre will study how their "health, wellbeing and body clock" are impacted by a set of variables that include lighting, food and drink, movement, sleep patterns and inflight entertainment.

机舱内的乘客将佩戴监控设备，查尔斯·帕金斯中心的专家将研究他们的“健康、幸福和生物钟”如何受到一系列变量的影响，包括灯光、食物和饮料、运动、睡眠模式和机上娱乐活动。

Monash University scientists will focus on the flight crew, recording their melatonin levels before, during and after the flights, as well as studying brain wave data from electroencephalogram devices worn by the pilots.

莫纳什大学(Monash University)的科学家们将把重点放在机组人员身上，记录他们在飞行前、飞行中以及飞行后的褪黑激素水平，同时研究飞行员佩戴的脑电图设备的脑电波数据。

This information will then be shared with the Civil Aviation Safety Authority "to help inform regulatory requirements associated with ultra-long haul flights," Qantas said in a press release.

澳航在一份新闻稿中表示，这些信息将与民航安全局共享，“以帮助了解与超长航班相关的监管要求。”

Alan Joyce, Qantas Group CEO, said in the press release: "Ultra-long haul flying presents a lot of common sense questions about the comfort and wellbeing of passengers and crew. These flights are going to provide invaluable data to help answer them."

澳航集团首席执行官艾伦•乔伊斯在新闻发布会上表示:“超长航程带来了许多关于乘客和机组人员舒适度和幸福感的常识问题。这些飞行将提供宝贵的数据来帮助回答这些问题。
