本课只做一件事：把「辐射与极端环境」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 Radiation & Extreme Environments 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

    WBGT / 湿球黑球温度
    综合干球、湿球（湿度）、黑球（辐射热）与气流的炎热度指数，用于热应激分级。
    A heat index blending dry bulb, wet bulb, globe and airflow, used to grade heat stress.
    易混 / Easily confused：易混：WBGT 与气温。WBGT 含湿度与辐射，通常高于气温。
    WBGT usually exceeds the air temperature reading.
    例句 / In a sentence：Humidity moves the band. / 湿度改档位。
    Inverse Square Law / 平方反比定律
    点源强度与距离平方成反比：I=1/d²，距离×2 强度÷4。
    Point-source intensity falls with the square of distance.
    易混 / Easily confused：易混：适用于点源；线源与面源衰减更慢，不能照搬。
    Point sources only; lines and areas fall off slower.
    例句 / In a sentence：Step back, quarter the dose. / 退一步，剂量除四。
    Ionizing Radiation / 电离辐射
    能量足以从原子移出电子的辐射（X/γ/α/β），损害直接且累积。
    Radiation energetic enough to strip electrons — X, gamma, alpha, beta — with direct, cumulative harm.
    易混 / Easily confused：易混：电离与非电离。α 外照射弱内照射强，防护逻辑不同。
    Alpha is trivial outside, deadly inside — different logic per type.
    例句 / In a sentence：Time, distance, shield. / 时间、距离、屏蔽。
    Laser Class / 激光分级
    按输出功率与波长分 1–4 类的安全分级，3B/4 类需控制区。
    Safety classes one to four by power and wavelength; 3B and 4 need controlled areas.
    易混 / Easily confused：易混：1 类「安全」指正常使用，改装或维修时可能暴露更高类输出。
    Class 1 assumes intact enclosure; servicing can expose higher classes.
    例句 / In a sentence：Class drives the room. / 类别决定区域。
    Acclimatization / 热习服
    经 10–14 天渐进热暴露获得的生理适应（出汗提前、心率下降）。
    Physiological adaptation over 10–14 days of graded heat exposure.
    易混 / Easily confused：易混：习服与耐力。习服可失去（约 1–2 周），返岗要重来。
    Acclimatization decays in a week or two; rehires restart.
    例句 / In a sentence：Earned slowly, lost fast. / 慢慢练，快快丢。
    Wind Chill / 风寒指数
    风速与低温叠加的体感寒冷度，决定冻伤所需时间。
    The perceived cold from wind plus low temperature, setting frostbite times.
    易混 / Easily confused：易混：风寒与气温。同一气温下风速翻倍，冻伤时间可减半以上。
    Doubling wind can halve frostbite time at the same temperature.
    例句 / In a sentence：Wind speeds the freeze. / 风加速冻结。

    情景自测 | Scenario check

    术语辨析Terminology

    这道题考什么：考 WBGT 的组成。
    Tests WBGT composition.

    干球 30 ℃、相对湿度 85% 的炉前车间，WBGT 读数会？

    A 30 C furnace deck at 85 percent humidity — its WBGT will be?

    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. 对比两个车间的 WBGT 组成并分级。
    Compare WBGT components for two shops and grade them.
