本课只做一件事：把「职业暴露评估策略」的 6 个高频英文术语从「眼熟」变成「能用」：定义、易混、例句。

Turn the six high-frequency terms of Exposure Assessment Strategy from familiar to usable: definition, look-alike, example.

本课不涉及：不扩到别的板块的术语，也不考题型技巧。
Not covered here: No terms from other blocks, no question-technique work.

本课目标 | Learning objectives

  1. 为每个术语说出定义，而不是只给中文对应词
  2. 指出每一对易混词差在哪一个限定条件上
  3. 把每个术语放进一句真实的现场英文里

  • Define each term rather than translate it
  • Point to the exact qualifier that separates each look-alike pair
  • Put each term into one real site sentence

    术语详解 | Glossary in depth

    SEG / 相似暴露组
    工种、任务、接触材料三要素相同的员工组，暴露评估的基本单元。
    Employees sharing job, task and materials; the unit of assessment.
    易混 / Easily confused：易混：SEG 与部门。部门是组织结构，SEG 是暴露结构。
    A department is org structure; a SEG is exposure structure.
    例句 / In a sentence：Same work, same air. / 同工同料同空气。
    Breathing Zone / 呼吸带
    口鼻前方约 30 cm 内的空气区，个体采样头的安放位置。
    The air within about 30 cm of the nose, where the sampling head sits.
    易混 / Easily confused：易混：呼吸带与工位。呼吸带跟着人走，工位是固定的。
    The breathing zone travels with the person; the workstation does not.
    例句 / In a sentence：Where the nose is. / 鼻子在哪，测哪。
    95% UCL / 95%置信上限
    真实均值有 95% 把握低于该值的统计上限，用于与 OEL 对比判定。
    The statistical upper bound on the true mean at 95 percent confidence, compared to the OEL.
    易混 / Easily confused：易混：UCL 与最大值。UCL 由均值与离散度推算，不是样本里的最大读数。
    The UCL is derived, not the largest sample.
    例句 / In a sentence：Bound the mean, not the max. / 估的是均值上限。
    OEL / 职业接触限值
    权威机构给出的空气中化学物浓度上限（OSHA PEL、ACGIH TLV 等）。
    An authoritative airborne concentration cap such as the PEL or TLV.
    易混 / Easily confused：易混：OEL 与 LD50。OEL 面向反复职业接触，LD50 是动物单次口径。
    OELs govern repeated work exposure; LD50 is a single animal dose.
    例句 / In a sentence：One number, one scope. / 一个数一个口径。
    Personal Sampling / 个体采样
    采样装置随人移动、采样头置呼吸带的测量方式。
    Measurement with the sampler worn and the head in the breathing zone.
    易混 / Easily confused：易混：个体与定点。定点测环境，个体测暴露；合规判定用个体。
    Area measures the room; personal measures the person.
    例句 / In a sentence：Follow the worker. / 让仪器跟人走。
    Relative Risk / 相对风险
    暴露组与对照组发病率之比，RR>1 提示暴露与疾病正相关。
    The ratio of disease incidence between exposed and unexposed; above one means positive association.
    易混 / Easily confused：易混：RR 与发病率。RR 是比值（无单位），发病率是速率（人·时间）。
    RR is a unitless ratio; incidence is a rate per person-time.
    例句 / In a sentence：Compare, then conclude. / 先比再下结论。

    情景自测 | Scenario check

    术语辨析Terminology

    这道题考什么：考发病率与患病率。
    Tests incidence versus prevalence.

    「2025 年某厂新增手部裂伤 12 例，全厂 300 人工作一年」计算出的指标是？

    'Twelve new hand lacerations in 2025 across 300 workers' computes which measure?

    自编练习题，不是 BCSP 官方真题，也不能用来预测分数。 / Original practice item, not an official BCSP exam question.

    动手练 | Practice

    1. 给车间写 SEG 清单并标出「不可判定」的组。
    Draft a SEG list and mark undecidable groups.
