　　China's second female astronaut, Wang Yaping, delivered the country's first-ever video lecture from space for about 40 minutes in the Tiangong-1 space laboratory about 340km above Earth on Thursday morning.

　　20日上午，中国第二位女航天员王亚平在距离地面约340公里的天宫一号太空实验室中进行了太空视频授课。这是中国首次进行太空授课，课时大约40分钟。

　　An estimated 60 million students and teachers across China were watching the lecture live on TV.

　　据估计，全国大约有6000万名师生在电视上观看了这次太空授课的直播。

　　Wang explained physics in zero-gravity in the lecture. She made different experiments to demonstrate the concepts of weight, mass and motion in space.

　　王亚平在课堂上讲解了失重状态下的物理现象。她做了多个不同的实验来诠释重量、质量和运动等在太空中的概念。

　　Wang showed how normal scales do not work inside the orbiter. Then she used a special quality measuring instrument to measure the weight of crew commander Nie Haisheng.

　　王亚平演示了普通的测量工具在飞行器里为何无法使用。随后，她用一个特制的质量测量仪测量了指令长聂海胜的体重。

　　Next, she used spinning tops and a small ball attached to a string to show how objects move in the microgravity environment of space. She also made a film of water by using a metal ring, explaining the increased surface tension of water in space.

　　接下来，她借助旋转的陀螺和系在绳上的小球来演示物体在太空微重力的环境中如何运动。她还用金属圈做了一个水膜，来说明水的表面张力在太空中会增强。

　　Around 330 primary and secondary school students watched the lecture from a classroom in Beijing, where they could ask Wang questions through a live video feed system.

　　大约330名中小学生聚在北京的一间教室里观看了太空授课，他们可通过实时视频系统向王亚平提问。

　　In response to a student's questions, Wang described what she could see in space. “The stars we see are much brighter, but they do not twinkle. The sky we see isn't blue, but deep black. And every day, we can see the sun rise 16 times because we circle the Earth every 90 minutes,” she said.

　　王亚平在回答一名同学的问题时描述了她在太空中看到的景象。她说：“我们看到的星星要明亮很多，不过它们不会闪烁。我们看到的天空不是蓝色的，而是深邃的黑色。我们每天都会看到16次日出，因为我们每90分钟就可以绕地球一圈。”
