第 59 块 · 综合复习 · Integrated Review第 3 / 5 课 · 术语精讲Lesson 3 of 5 · Glossary Focus

本课只做一件事：把「综合复习：D1 计算专项」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 Review: D1 Calculations 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

    Fall Distance / 坠落距离
    从失衡到停止下坠的垂直距离：自由坠落+缓冲展开。
    The vertical drop from loss of balance to stop: free fall plus deceleration.
    易混 / Easily confused：易混：坠落距离与净空。净空还要加 D 环到鞋底与余量。
    Clearance adds the D-ring height and margin.
    例句 / In a sentence：Free fall = rope − anchor rise. / 自由坠落=绳长−锚点高差。
    Safety Distance / 安全距离 Ds
    压床/光幕到危险区的最小距离，按总停止时间计算。
    The minimum distance from guard to hazard from total stop time.
    易混 / Easily confused：易混：Ds 与工作空间。Ds 防手快，工作空间防人挤。
    Ds beats hand speed; clearance layouts beat crowding.
    例句 / In a sentence：Ds = 63 in/s × T. / 最小 7 英寸。
    Noise Conversion / 噪声换算
    按交换率把剂量与允许时间互算：OSHA 5 dB、NIOSH 3 dB。
    Converting dose to allowed time by exchange rate: OSHA 5 dB, NIOSH 3 dB.
    易混 / Easily confused：易混：两套口径。题干写 NIOSH 才用 3 dB。
    The item must say which rule applies.
    例句 / In a sentence：90 dBA = 8 h (OSHA). / 95 dBA = 4 h。
    TRIR / 总记录工伤率
    可记录工伤例数×200,000÷总工时，行业对标主指标。
    Recordable cases times 200,000 over hours worked.
    易混 / Easily confused：易混：TRIR 与 DART。DART 只数限制工作/调岗/离岗例。
    DART is the restricted-and-lost subset.
    例句 / In a sentence：Denominator = hours. / 分母是工时。
    Unit Trap / 单位陷阱
    题干混用单位制（lb/kg、inch/cm、dBA）制造的错误路径。
    Mixed units planted in the stem to derail the unwary.
    易混 / Easily confused：易混：陷阱与错误。陷阱是设计，统一单位是免疫。
    One unit system is the vaccine.
    例句 / In a sentence：Convert before you compute. / 先换算再计算。
    Drill Card / 口算卡
    错题浓缩卡：题目特征→公式→答案量级，三行一面。
    A three-line miss card: pattern, formula, answer magnitude.
    易混 / Easily confused：易混：口算卡与错题本。卡管提取速度，本管归因。
    The log explains; the card speeds recall.
    例句 / In a sentence：Sweep it daily. / 每天过一遍。

    情景自测 | Scenario check

    术语辨析Terminology check

    这道题考什么：考噪声换算口径。
    Tests the noise exchange rate.

    按 OSHA 口径，100 dBA 的连续暴露允许时长是？

    Under OSHA, the allowed duration at 100 dBA is?

    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. 写三张口算卡：坠落净空、Ds、TRIR。
    Write three drill cards: clearance, Ds, TRIR.
