“我们的征途是星辰大海”—这句话是如此地鼓舞人心,仿佛我们都是宇宙的水手,等待着探索新世界的启航号角。没错,我们身体里的金属元素都来自于恒星的中心,从某种意义上来说,我们都是属于宇宙深空的孩子。今天,就让我们以科幻作品为引子,从现实中的物理出发,来看看那些奇妙的宇宙航行方法吧!传统火箭引擎——化学引擎为了能够前进,我们必须向着运动的相反方向掷出一定的质量,这些投掷出去的东西叫做“工质”。工质推进是目前帮助我们摆脱重力束缚,迈出离开地球母亲怀抱第一步的不可缺少方式。
“Our journey is the sea of stars ” - this sentence is so inspiring, as if we are all cosmic sailors, waiting to explore the new world sail horn. Yes, the metal elements in our bodies come from the center of the stars. In a sense, we are all children belonging to the deep space universe. Today, let’s take a science-fiction work as a guide and look at the fantastic cosmic approach from the physics in the real world! Traditional Rocket Engine - Chemical Engine In order to move forward, we must roll a certain amount toward the opposite direction of the movement The quality of these throwing things called “working fluid ”. Working-substance advancement is now an indispensable way to help us get out of the grip of gravity and take the first step towards leaving the Mother Earth.
