💧 渗透压（范特霍夫方程）Osmotic Pressure Calculator

使用说明与常见问题How-to & FAQ

「渗透压（范特霍夫方程）」是什么？What is the Osmotic Pressure Calculator tool?

π = i M R T：i 为解离因子，M 为摩尔浓度 mol/L，R = 0.082057 L·atm/(mol·K)，T 为绝对温度。本地处理。π = i M R T: i dissociation factor, M molarity in mol/L, R = 0.082057 L·atm/(mol·K) and T the absolute temperature. Processed locally.

如何使用「渗透压（范特霍夫方程）」？How do I use the Osmotic Pressure Calculator tool?

填写解离因子 i、摩尔浓度和温度，即可得到渗透压 π = iMRT。结果会随输入实时更新。Enter the dissociation factor i, the molarity and the temperature to get the osmotic pressure π = iMRT. The result updates as you type.

生理盐水？Normal saline?

0.9% NaCl 约 0.154 mol/L，i ≈ 2，37 °C 时约 7.6 atm。0.9% NaCl is about 0.154 mol/L with i ≈ 2 - about 7.6 atm at 37 °C.

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

例如在「渗透压（范特霍夫方程）」中填 解离因子 i = 1，摩尔浓度 mol/L = 0.1，温度 °C = 25，结果区显示：渗透压：2.4465 atm；千帕：247.9 kPa；毫米汞柱：1,859.4 mmHgFor example, entering Dissociation factor i = 1, Molarity mol/L = 0.1, Temperature °C = 25 in the Osmotic Pressure Calculator gives: Osmotic pressure: 2.4465 atm; Kilopascals: 247.9 kPa; mmHg: 1,859.4 mmHg

哪些输入会被检查？Which inputs are validated?

「渗透压（范特霍夫方程）」会检查这些输入——「解离因子 i」、「摩尔浓度 mol/L」：必须填写，须大于 0；「温度 °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 Osmotic Pressure Calculator checks its inputs — "Dissociation factor i", "Molarity mol/L": required, must be greater than 0; "Temperature °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?

「渗透压（范特霍夫方程）」的设置：「解离因子 i」默认 1；「摩尔浓度 mol/L」默认 0.1；「温度 °C」默认 25。每次生成结果都按当前设置处理。Settings in the Osmotic Pressure Calculator — "Dissociation factor i" default 1; "Molarity mol/L" default 0.1; "Temperature °C" default 25. 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?

「渗透压（范特霍夫方程）」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 Osmotic Pressure 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.

「渗透压（范特霍夫方程）」免费吗？需要注册吗？Is the Osmotic Pressure Calculator free? Do I need an account?
