⚗️ 产率计算器（百分产率）Percent Yield Calculator

使用说明与常见问题How-to & FAQ

「产率计算器（百分产率）」是什么？What is the Percent Yield Calculator tool?

用 实际产量 ÷ 理论产量 × 100% 计算化学反应的百分产率，也可由产率和理论产量反求实际产量，或由实际产量和产率反求理论产量。Calculate the percent yield of a reaction, actual ÷ theoretical × 100%, or solve for the actual yield or theoretical yield from the other two.

如何使用「产率计算器（百分产率）」？How do I use the Percent Yield Calculator tool?

在「产率计算器（百分产率）」中，填写「求解」、「实际产量」、「理论产量」、「百分产率 %」、「单位」等参数，结果会随输入实时计算并显示在下方。In the Percent Yield Calculator: Fill in "Solve for", "Actual yield", "Theoretical yield", "Percent yield %", "Unit"; results are recalculated instantly as you type.

百分产率怎么算？How is percent yield calculated?

百分产率 = 实际产量 ÷ 理论产量 × 100%。理论产量由限量试剂按化学计量关系算出，实际产量是实验得到的产物质量。Percent yield = actual yield ÷ theoretical yield × 100%. The theoretical yield comes from the limiting reagent and the stoichiometry; the actual yield is what you isolate.

产率为什么通常低于 100%？Why is yield usually below 100%?

副反应、反应不完全、转移和纯化过程中的损失都会降低产率。超过 100% 通常意味着产物含溶剂或杂质。Side reactions, incomplete reaction and losses during transfer and purification all lower it; more than 100% usually means solvent or impurities remain.

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

「产率计算器（百分产率）」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 Percent Yield 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.

「产率计算器（百分产率）」免费吗？需要注册吗？Is the Percent Yield Calculator free? Do I need an account?

「产率计算器（百分产率）」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 Percent Yield 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.
