公式表与备考系统 · 概念解析 | Formula Sheet & Study System · Core Concepts

第 5 块 · 备考基线 · Exam Baseline第 1 / 5 课 · 概念解析Lesson 1 of 5 · Core Concepts

本课只做一件事：搞清「公式表与备考系统」到底是什么、为什么考试要先过这一关、它管到哪里为止。

Get clear on what Formula Sheet & Study System really is, why it comes first, and where it stops.

本课不涉及：不展开细节与题目——那是第 2–5 课的事。
Not covered here: No detail, no questions — those are lessons 2 to 5.

本课目标 | Learning objectives

  1. 能用一句话说清「公式表与备考系统」解决的是什么问题
  2. 能举出一个「不懂它就一定做错」的例子
  3. 知道本课的边界，不把后续课的内容提前混进来

  • State in one sentence the problem Formula Sheet & Study System solves
  • Give one example where missing it guarantees a wrong answer
  • Know this lesson's boundary and keep later lessons out

    它是什么 | What it is

    公式表不是公式清单，而是一页「决策索引」：题目给出一串数字，你先判断它问的是频率（rate）、严重度（severity）、暴露剂量（dose/TWA），还是成本与概率；判断对了，剩下的只是代入。备考系统是配合它的三件事：按蓝图权重排顺序、用检索与间隔记、按错因纠错。

    A formula sheet is not a list of formulas but an index for decisions: given a string of numbers, first decide whether the item asks for a rate, a severity, an exposure dose, or a cost and probability. Get that right and only substitution remains. The study system is the three things that go with it: order by blueprint weight, remember by retrieval and spacing, correct by error type.

    为什么先学它 / Why first
    计算题在 CSP 里数量不多，但失分很集中，而且一错就连带后面的判断错：TRIR 算成 25 而不是 2.5，后面「哪一项该优先」的判断会全部反过来。备考系统则决定 366 天的长线能不能撑住——没有它，第 100 天一定会开始忘第 10 天。
    Calculation items are few on the CSP but losses cluster there, and one error cascades: compute TRIR as 25 instead of 2.5 and every later priority judgement inverts. The study system decides whether a 366-day run holds — without it, day 100 starts forgetting day 10.
    它管到哪里为止 / Where it stops
    本块不推导统计推断（置信区间、假设检验），不覆盖全部工业卫生采样计算（Domain 6 展开），也不替代官方蓝图。考试若在题干里给出公式，一律以题干为准。
    This block does not derive statistical inference (confidence intervals, hypothesis tests), does not cover all industrial hygiene sampling maths (Domain 6), and does not replace the official blueprint. If an item supplies a formula, the item wins.

    先认个脸 | Terms you will meet

    1. Incidence Rate — 发病率 / 事故率
    2. Exposure Hours — 暴露工时
    3. DART Rate — 缺勤与受限工作率
    4. TWA — 时间加权平均浓度
    5. PEL / REL / TLV — 容许限值 / 建议限值 / 阈限值
    6. Severity Rate — 严重度率

    这里只要求认得；定义、易混与例句在本块第 3 课「术语精讲」。/ Recognition only — definitions come in the glossary lesson of this block.

    情景自测 | Scenario check

    本课理解Lesson comprehension

    这道题考什么：考「先判断问什么，再选公式」这个顺序，而不是背公式本身。
    Tests the order — decide what is asked, then pick the formula — not formula recall.

    题干给出「12 起可记录病例、950,000 工时、4 起缺勤」，最先该做的一步是什么？

    An item gives 12 recordable cases, 950,000 hours worked and 4 lost-time cases. What is the first step?

    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. 用一句话说清「公式表」和「公式清单」的区别。
    State in one sentence how a formula sheet differs from a list of formulas.
