ejection的讀音是：[??d?ek?n]，音標(biāo)為/"a?d??k??n/。

ejection的基本意思是“驅(qū)逐”，指由于某種原因而把某人或某物從所在的地方趕出去，也可指某人或某物被拋出或彈出。

在速記技巧方面，可以通過聯(lián)想記憶法來記住這個單詞，例如：eject這個詞可以聯(lián)想到expel（驅(qū)逐），這兩個詞在記憶時可以結(jié)合在一起記，這樣不容易混淆。

ejection的英文詞源是拉丁語ex-和-jectum，意思是“拋出”。

變化形式：過去式ejected，過去分詞ejected，現(xiàn)在分詞ejecting，復(fù)數(shù)形式ejects。

相關(guān)單詞：

- expulsion：驅(qū)逐，開除；驅(qū)逐出境。

- eject：驅(qū)逐，趕出；噴射。

- ejector：噴射器；驅(qū)逐器。

- ejector seat：噴射座椅。

- ejectable：可驅(qū)逐的。

- ejectment：驅(qū)逐；被驅(qū)逐。

- ejectionist：驅(qū)逐主義者。

- ejection velocity：射出速度。

- ejectable matter：可驅(qū)除物。

- ejector pump：噴射泵。

在英語中，ejection這個詞常常與驅(qū)逐、開除、噴射等動作和概念相關(guān)聯(lián)。這些單詞不僅豐富了英語詞匯，也反映了英語作為一門語言的豐富性和多樣性。

The importance of ejection systems in spacecraft design

Spacecraft design requires a variety of systems to ensure safe and reliable operation. One such system is the ejection system, which is used to eject critical components in case of a malfunction or emergency situation. Ejection systems allow spacecraft to continue functioning even if a component fails, providing additional redundancy and ensuring mission success.

In spacecraft design, ejection systems are commonly used for fuel tanks, thrusters, and other critical components that need to be quickly removed in case of an emergency. These systems typically include a valve that allows the component to be quickly ejected, usually through a spring-loaded mechanism or a pyrotechnic device. Ejection systems provide a fail-safe mechanism that ensures mission success in case of a malfunction or emergency.

However, designing an effective ejection system is not an easy task. It requires careful consideration of various factors, including component weight, launch velocity, and the environment in which the spacecraft will operate. Additionally, ensuring that the system is reliable and safe for use requires extensive testing and validation.

Overall, ejection systems play an important role in spacecraft design, providing additional redundancy and ensuring mission success in case of a malfunction or emergency situation. They are essential components of any spacecraft that require maximum reliability and safety for their mission success.
