常见错误

❌ 错误:The theory is very demonstrable.
✓ 正确:The theory has high demonstrability.

Demonstrability 是名词,不能直接用形容词 very 修饰理论本身,应使用名词形式搭配 have/possess 或直接用 highly demonstrable 作形容词短语。

❌ 错误:We need to make the result more demonstrable.
✓ 正确:We need to enhance the demonstrability of the result.

当强调“性质”而非“状态”时,使用名词 demonstrability 更符合学术表达习惯;make...demonstrable 虽语法正确但略显口语化。

近义词辨析

verifiability

Verifiability 侧重于‘可被验证’,强调通过测试或检查来确认真假;Demonstrability 更侧重‘可被展示/演示’,强调直观呈现或逻辑推导出的可见性。

The validity of the model is verifiable through data, but its real-world applicability lacks demonstrability.

provability

Provability 通常指通过逻辑推理证明某事为真(如数学定理);Demonstrability 范围更广,包括实验、观察或实际演示等多种证明方式。

The theorem is provable, yet the physical phenomenon it describes has limited demonstrability in a lab setting.
