⚗️ 摩尔比计算器Molar Ratio Calculator
由两份物质的量 n1、n2 给出比值 n1/n2 与未约分的 n1 : n2。二者须大于 0。本地处理。From amounts n1 and n2 get the quotient n1/n2 and the unreduced ratio n1 : n2. Both must be greater than 0. Processed locally.
使用说明与常见问题How-to & FAQ
「摩尔比计算器」是什么？What is the Molar Ratio Calculator tool?
由两份物质的量 n1、n2 给出比值 n1/n2 与未约分的 n1 : n2。二者须大于 0。本地处理。From amounts n1 and n2 get the quotient n1/n2 and the unreduced ratio n1 : n2. Both must be greater than 0. Processed locally.
如何使用「摩尔比计算器」？How do I use the Molar Ratio Calculator tool?
在「摩尔比计算器」中，填写「n₁」、「n₂」等参数，结果会随输入实时计算并显示在下方。In the Molar Ratio Calculator: Fill in "n₁", "n₂"; results are recalculated instantly as you type.
能算三种物质的比例吗？Can it compare three species?
不能，本页只比较两种物质：给出 n₁ : n₂ 和它们的商。三种物质时，可以分别把每一个都除以最小的那个，得到类似 1 : 2.5 : 3 的比例。No, only two: it gives n₁ : n₂ and their quotient. For three, divide each amount by the smallest one to get a ratio such as 1 : 2.5 : 3.
能举个计算实例吗？Can you show a worked example?
例如在「摩尔比计算器」中填 n₁ = 2，n₂ = 6，结果区显示：n₁/n₂：0.33333333；比（未约分）：2 : 6For example, entering n₁ = 2, n₂ = 6 in the Molar Ratio Calculator gives: n₁/n₂: 0.33333333; Ratio (unreduced): 2 : 6
哪些输入会被检查？Which inputs are validated?
「摩尔比计算器」会检查这些输入——「n₁」、「n₂」：必须填写，须大于 0；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 Molar Ratio Calculator checks its inputs — "n₁", "n₂": required, must be greater than 0; 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?
「摩尔比计算器」的设置：「n₁」默认 2；「n₂」默认 6。每次生成结果都按当前设置处理。Settings in the Molar Ratio Calculator — "n₁" default 2; "n₂" default 6. 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?
「摩尔比计算器」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 Molar Ratio Calculator 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.
「摩尔比计算器」免费吗？需要注册吗？Is the Molar Ratio Calculator free? Do I need an account?
「摩尔比计算器」完全免费，无需注册或安装，打开网页即可使用，手机和电脑都能用；输入的内容只在你的浏览器本地处理。The Molar Ratio Calculator is completely free with no sign-up or install and works on phones and desktops; what you enter is processed only in your browser.
