Scientific Vocabulary: 研究, 实验, 数据, 模型, 机制

Scientific Chinese is built from repeatable frames

A Chinese scientific paragraph often looks intimidating because it compresses question, method, data, result, interpretation, and limitation into dense phrases. But the vocabulary is highly patterned. Once you recognize word families around 研究, 实验, 数据, 模型, and 机制, scientific reading becomes more manageable.

The most important skill is to distinguish what was done, what was found, and how strongly the text claims it.

Core word families

Claim verbs matter

Scientific Chinese uses verbs that encode evidence strength.

Do not translate every result verb as “says.” 研究表明 is not “research says” in natural English. It is “research shows/indicates.” 研究发现 is “the study found.”

模型 and 机制 are not everyday “model” and “mechanism” only

模型 can mean a physical model, mathematical model, conceptual model, prediction model, machine-learning model, or simplified representation. Context decides.

• 理论模型 — theoretical model.
• 预测模型 — predictive model.
• 语言模型 — language model.
• 动物模型 — animal model.
• 经济模型 — economic model.

机制 means mechanism, but not always a machine-like mechanism. It often means the process, causal pathway, institutional arrangement, or system by which something occurs.

• 作用机制 — mechanism of action.
• 形成机制 — formation mechanism.
• 调节机制 — regulatory mechanism.
• 运行机制 — operating mechanism.

Abstract-reading template

When reading a Chinese abstract or science summary, mark these components:

1. Question: 本研究旨在… / 为探讨…
2. Method: 采用…方法 / 通过实验… / 基于…数据
3. Data: 样本, 变量, 指标, 数据来源
4. Result: 结果显示 / 研究发现 / 数据表明
5. Interpretation: 说明 / 可能表明 / 支持…假设
6. Limitation: 仍需进一步验证 / 样本有限 / 有待研究
7. Implication: 为…提供依据 / 对…具有意义

Example paragraph

基于三年的样本数据，研究人员建立了预测模型。结果表明，变量A与变量B之间存在显著相关性，但其作用机制仍有待进一步验证。

This sentence does not claim causation. It claims significant correlation and says the mechanism still needs verification.

Everyday vs scientific meanings

Build an abstract annotation tool. Users paste a short Chinese science paragraph and label question, method, data, result, relation, mechanism, and limitation. Include a claim-strength slider for 推测, 表明, 证明, and 验证.

Quality-pass expansion

Additional diagnostic drills

Drill 1: Relatedness is not causation.

Drill 2: Hypothesis, model, mechanism.

• 假设 is the proposed explanation or testable claim.
• 模型 is a representation or predictive/explanatory structure.
• 机制 is the process or pathway by which something happens.

A strong final article should include this triad because learners often translate all three vaguely as “theory.” In scientific reading, the distinctions matter.

Remediation and upgrade pass

Scientific vocabulary needs an evidence-strength ladder. Learners often translate 研究表明, 证明, 显示, 提示, and 推测 as if they all mean “prove.” They do not.

Added abstract-reading template

Ask readers to annotate:

1. 研究对象: What population/material/system is studied?
2. 研究问题: What question is being asked?
3. 方法: Experiment, survey, model, observation, comparison?
4. 数据/样本: What evidence base?
5. 结果: What was found?
6. 机制/解释: How is the result explained?
7. 局限/有待: What remains uncertain?
