They will carry out extravehicular activities, install extravehicular payloads and conduct space station maintenance and other tasks, Lin said.

他们将执行舱外活动，安装舱外有效载荷，进行空间站维护和其他任务，林。

Other key payloads include the space high-energy particle detection equipment, which completed an extravehicular mission.

此外，空间高能粒子探测载荷完成首次舱外探测任务。

Wang Ya'nan, chief editor of Aerospace Knowledge magazine, said extravehicular repair operations are sophisticated and challenging.

《知识》杂志主编王亚男表示，舱外维修工作复杂又具有挑战性。

The Shenzhou-17 astronauts will do extravehicular experimental maintenance for the first time, which is a very challenging task, Lin added.

林补充， 17 号宇员将首次进行舱外实验维护，这是一项非常具有挑战性的任务。

Some taikonauts engaged in extravehicular activities reported seeing flashes that didn't exist.

一些从事舱外活动的宇员报告看到了不存在的闪光。

During their mission, the Shenzhou-16 crew will continue to conduct extravehicular activities and cargo airlock extravehicular tasks, space science experiments, and the trial of new technologies.

在其任务期间，16号的宇员将继续进行舱外活动和货物气闸舱外任务，空间科学实验，和新技术的试验。

The extravehicular activities (EVAs) started at 1: 35 p.m. Beijing Time on Saturday, when taikonaut Cai Xuzhe opened the hatch of the airlock cabin of the Wentian lab module.

舱外活动于北京时间周六下午 1 点 35 分开始，当时中国宇员蔡旭哲打开了问实验室舱气闸舱的舱门。

The taikonauts completed a series of tasks, including installing an extravehicular assistance handle to help them open the hatch from outside the space station in an emergency and additional pumps – the core equipment in the space station's thermal control system.

宇员完成了一系列任务，包括安装一个舱外助力手柄，帮助他们从舱外把气闸舱舱门打开（的情况）；并安装舱外载荷扩展泵组，这是空间站热控制系统的核心设备。
