本课只做一件事：把「人体工效与疲劳管理」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 Ergonomics & Fatigue Management 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

    Circadian Rhythm / 昼夜节律
    约 24 h 的生理周期（体温、警觉、激素），夜班工作与其对抗。
    The roughly 24-hour physiological cycle of temperature, alertness and hormones that night work fights.
    易混 / Easily confused：易混：节律与习惯。节律是生理性的，靠黑暗与光照重置，不靠自觉。
    The clock is physiological, reset by light and dark, not attitude.
    例句 / In a sentence：Light resets the clock. / 光照重置节律。
    Forward Rotation / 顺时针轮班
    按早→中→夜方向轮转的排班法，与节律天然倾向一致。
    Rotating morning to swing to night, aligned with the body clock's drift.
    易混 / Easily confused：易混：顺/逆时针方向。逆时针要求提前入睡，生理逆风。
    Backward rotation demands earlier sleep, against the drift.
    例句 / In a sentence：Rotate with the clock. / 顺着钟转。
    Micro-break / 微休息
    每约 2 小时 5 分钟的短时活动休息，用于打断连续负荷累积。
    A five-minute active pause about every two hours to break load accumulation.
    易混 / Easily confused：易混：微休息与工间休。前者短频且活动，后者长而稀。
    Short, frequent and active beats long and rare.
    例句 / In a sentence：Move, don't scroll. / 要活动不要刷手机。
    HAVS / 手传振动综合征
    长期手传振动致的白指、麻木与握力下降，损害不可逆。
    Hand-arm vibration syndrome: white finger, numbness and grip loss, irreversible.
    易混 / Easily confused：易混：HAVS 与腕管综合征。病因不同（振动 vs 重复压迫），症状可重叠。
    Different cause from carpal tunnel, overlapping symptoms.
    例句 / In a sentence：Once white, always cold. / 白指不可逆。
    Work-rest Cycle / 作休循环
    按 WBGT 等级与代谢率设定的「工作 X 分钟/休息 Y 分钟」节奏。
    The work-X, rest-Y rhythm set by WBGT band and metabolic rate.
    易混 / Easily confused：易混：作休循环与午休。前者按热负荷动态调整，后者是固定制度。
    The cycle moves with heat load; lunch is fixed.
    例句 / In a sentence：The heat sets the cycle. / 热度定节奏。
    Sleep Hygiene / 睡眠卫生
    保障睡眠质量的成套行为：遮光、静音、规律、避免睡前兴奋剂。
    Behaviours protecting sleep quality: darkness, quiet, regularity, no late stimulants.
    易混 / Easily confused：易混：睡眠卫生与睡眠时长。时长靠排班给，质量靠卫生保。
    Rosters give the hours; hygiene gives the quality.
    例句 / In a sentence：Dark, quiet, regular. / 遮光、护静、规律。
