🧪 比尔-朗伯定律Beer-Lambert Law

使用说明与常见问题How-to & FAQ

「比尔-朗伯定律」是什么？What is the Beer-Lambert Law tool?

A = ε c l。本地处理。可设置「ε」、「浓度 c」、「光程 l」。A = ε c l. Processed locally. Settings: ε, Concentration c, Path length l.

如何使用「比尔-朗伯定律」？How do I use the Beer-Lambert Law tool?

在「比尔-朗伯定律」中，填写「ε」、「浓度 c」、「光程 l」等参数，结果会随输入实时计算并显示在下方。In the Beer-Lambert Law: Fill in "ε", "Concentration c", "Path length l"; results are recalculated instantly as you type.

透射？Transmittance?

T = 10^(-A)。T = 10^(-A).

能举个计算实例吗？Can you show a worked example?

例如在「比尔-朗伯定律」中填 ε = 1000，浓度 c = 0.01，光程 l = 1，结果区显示：吸光度 A：10For example, entering ε = 1000, Concentration c = 0.01, Path length l = 1 in the Beer-Lambert Law gives: Absorbance A: 10

哪些输入会被检查？Which inputs are validated?

「比尔-朗伯定律」会检查这些输入——「ε」、「光程 l」：必须填写，须大于 0；「浓度 c」：必须填写；绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示，不会给出数字。The Beer-Lambert Law checks its inputs — "ε", "Path length l": required, must be greater than 0; "Concentration c": required; numbers above 10¹⁵ in absolute value are rejected too. When a value fails, the result area names the problem instead of showing a number.

有哪些选项可以调整？What options can I adjust?

「比尔-朗伯定律」的设置：「ε」默认 1000；「浓度 c」默认 0.01；「光程 l」默认 1。每次生成结果都按当前设置处理。Settings in the Beer-Lambert Law — "ε" default 1000; "Concentration c" default 0.01; "Path length l" default 1. The result always uses the current settings.

计算结果可以用于作业或工程吗？Can I use the results for homework or engineering?

「比尔-朗伯定律」使用教科书标准公式（公式写在说明和常见问题中），适合学习和估算核对；涉及安全的工程设计请以规范和实测为准。The Beer-Lambert Law uses standard textbook formulas (given in the description and FAQ), which is good for learning and checking estimates; for safety-critical engineering follow codes and measured values.
