?一、escape_velocity是什么意思(中英文)解釋的意思:
escape_velocity是一個物理學(xué)術(shù)語,指的是一個物體需要達(dá)到的速度,才能克服重力場逃離天體表面。它是一個重要的概念,被廣泛應(yīng)用于航天領(lǐng)域和天體物理學(xué)研究中。
英文釋義:Escape velocity is the speed that an object needs to achieve in order to overcome the gravitational pull of a celestial body and escape its surface. It is an important concept used in aerospace engineering and astrophysics research.
[??ske?p v??l?s?ti]
escape_velocity作為一個名詞,在句子中通常作主語或賓語使用。它可以指某個具體的速度值,也可以泛指達(dá)到逃逸所需的速度。
1. The spacecraft needs to reach a speed of 11.2 kilometers per second in order to achieve escape velocity from Earth. (這艘航天器需要達(dá)到每秒11.2公里的速度,才能從地球上實現(xiàn)逃逸速度。)
2. The escape velocity of the Moon is much lower than that of Earth due to its smaller size and weaker gravitational pull. (月球的逃逸速度比地球低得多,因為其尺寸較小,重力場也較弱。)
3. Scientists are studying the escape velocity of black holes to better understand their properties and behavior. (科學(xué)家正在研究黑洞的逃逸速度,以更好地了解它們的特性和行為。)
4. The escape velocity of a rocket is affected by various factors such as the mass of the rocket, the gravitational pull of the planet, and atmospheric conditions. (火箭的逃逸速度受到諸多因素的影響,如火箭的質(zhì)量、行星的重力場以及大氣條件。)
5. The escape velocity required for a successful mission to Mars is much higher than that for a mission to the Moon. (成功執(zhí)行火星任務(wù)所需的逃逸速度比月球任務(wù)高得多。)
1. Orbital velocity:軌道速度,指物體在繞行天體運動時所需的最小速度。
2. Launch velocity:發(fā)射速度,指發(fā)射物體所需達(dá)到的速度。
3. Critical velocity:臨界速度,指剛好能克服重力場而不會飛離天體表面的最低速度。
escape_velocity是一個重要概念,它幫助我們理解天體物理學(xué)和航天工程中關(guān)于運動和重力場等方面的問題。它也是航天任務(wù)設(shè)計和計算中不可或缺的參考參數(shù)。通過深入了解escape_velocity,我們可以更加深入地探索宇宙的奧秘。
