immobile

Compared meaning: not moving or not changing (adjective).

比较义项：不动的，不变的（形容词）。

• fixed

  Describes something set firmly in place or established as unchanging, often used for abstract things like prices, rules or opinions, not just physical objects.

  表示某事物被牢固地固定住，或被确立为不再改变，常用于价格、规则、看法等抽象事物，而不仅限于实物。

  The price of the meal is fixed, so it never changes.

  这顿饭的价格是固定的，所以它永远不会改变。

• stationary

  Describes something physically capable of movement that is currently not moving, commonly used for vehicles, machines or people staying still, contrasted with a normally moving state.

  表示某个本来能够移动的事物（如车辆、机器或人）目前处于静止状态，常用于车辆、机器或人保持不动的场景，与通常会移动的状态形成对比。

  The bike stayed stationary while he pedaled hard indoors.

• immobile 本词

  Describes someone or something unable to move, often due to injury, paralysis or being stuck, stressing a lack of ability to move rather than simply resting.

  表示某人或某物因受伤、瘫痪或被卡住等原因而完全无法移动，强调“没有能力移动”，而不只是暂时休息不动。

  After the accident, his injured leg remained immobile for several weeks.

  事故发生后，他受伤的腿有好几周都动弹不得。

Fixed, stationary, and immobile all mean not moving, but they apply differently. Fixed means set firmly in place or unchanging, like a price or rule. Stationary describes something that can move but is currently still, like a vehicle. Immobile describes someone unable to move.

这三个词都可以表示“不动”或“不变”，但语气和侧重不同：fixed 常指价格、规则等抽象事物固定不变；stationary 强调本可移动的事物（如车辆、机器）暂时静止不动；immobile 强调因受伤、瘫痪等原因而完全无法移动。这里不比较 fixed 表示“被操纵的”（如 a fixed match）或“修理好的”（get something fixed）的意思。
