empirical

Compared meaning: based on practical testing or observation, not theory (adjective).

比较义项：以实验或实际观察为依据（而非纯理论）（形容词）。

• experimental

  Describes something still being tried out or tested, often new and unproven, used for methods, drugs or techniques not yet confirmed to work.

  表示某事物仍处于试验或测试阶段，通常是新的、尚未证实的，用于描述尚未确认有效的方法、药物或技术。

  The lab is testing an experimental vaccine that hasn't been approved yet.

  实验室正在测试一种尚未获批的实验性疫苗。

• empirical 本词

  Describes conclusions, data or methods based on observation or experience rather than pure theory; common in describing evidence and research findings.

  表示结论、数据或方法基于观察或经验，而非纯理论；常用于描述证据和研究结果。

  Doctors rely on empirical evidence, not just theories, to choose treatments.

  医生依据经验证据而非单纯理论来选择治疗方案。

Both relate to being based on practice, not pure theory. Experimental describes something still being tried or tested, often new and unproven, like a method or drug. Empirical describes conclusions or methods based on observation or experience, common in describing evidence and research.

这两个词都与“以实践为依据”有关，但侧重不同：experimental 强调“仍处于试验阶段、尚未证实”，带有尝试、探索的意味；empirical 强调“基于实际观察或经验得到的证据”，常与“理论”相对，语气更中性、偏学术。两者不能互换使用。
