In Bordeaux, the 3D printing process is being researched in a parabolic flight.

在波尔多， 3D 打印过程正在抛物线飞行中进行研究。

The metal powder is in a container at the beginning of the parabolic flight.

金属粉末在抛物线飞行开始时位于容器中。

That is a particular challenge for the scientists, as the gravitational force during a parabolic flight varies.

这对科学家来说是一个特殊的挑战，因为抛物线飞行期间的引力会发生变化。

ANDREW LELAND: And so the plan for today is that all of us are gonna get on this plane and do what is called a parabolic flight.

安德鲁·利兰：所以今天的计划是我们所有人都将登上这架飞机并进行所谓的抛物线飞行。

We can get a taste of it on a parabolic flight, but it's just not the same as actually living and working in weightlessness up here, and it's not just fun but it's also very challenging.

我们可以在抛物线飞行中体验一下，但这和在失重状态下生活和工作是不一样的，这不仅很有趣，而且也很有挑战性。
