💧 含水率计算器（干基/湿基互换、加水或烘干到目标）Moisture Content Calculator (Dry or Wet Basis, Water to Add or Remove)

使用说明与常见问题How-to & FAQ

「含水率计算器（干基/湿基互换、加水或烘干到目标）」是什么？What is the Moisture Content Calculator (Dry or Wet Basis, Water to Add or Remove) tool?

由湿重和干重计算含水率，同时给出干基（水 ÷ 干重，木材和土壤常用）和湿基（水 ÷ 湿重，粮食和食品常用）两种结果；也可以在两种基准之间换算，或计算把一批物料调整到目标含水率需要去除或加入多少水。本地处理。Work out moisture content from wet and dry weight on both the dry basis (water / dry weight, used for wood and soil) and the wet basis (water / wet weight, used for grain and food), convert between the two, or find how much water to remove or add to bring a batch to a target moisture.

如何使用「含水率计算器（干基/湿基互换、加水或烘干到目标）」？How do I use the Moisture Content Calculator (Dry or Wet Basis, Water to Add or Remove) tool?

在「含水率计算器（干基/湿基互换、加水或烘干到目标）」中，填写「计算」、「湿重」、「干重」、「含水率 %」、「已知值的基准」等参数，结果会随输入实时计算并显示在下方。In the Moisture Content Calculator (Dry or Wet Basis, Water to Add or Remove): Fill in "Calculate", "Wet weight", "Dry weight", "Moisture %", "Basis of the known value"; results are recalculated instantly as you type.

干基和湿基有什么区别？What is the difference between dry and wet basis?

干基含水率 = 水 ÷ 干重，可以超过 100 %，木材和土壤常用；湿基含水率 = 水 ÷ 湿重（总重），总小于 100 %，粮食、饲料和食品常用。Dry basis = water / dry weight and can exceed 100 %; it is used for wood and soil. Wet basis = water / wet (total) weight, always below 100 %, used for grain, feed and food.

两种基准怎么换算？How do I convert between them?

湿基 = 干基 ÷ (1 + 干基)；干基 = 湿基 ÷ (1 − 湿基)（都用小数）。例如湿基 20 % 等于干基 25 %。Wet = dry / (1 + dry) and dry = wet / (1 − wet), as decimals. A wet basis of 20 % is a dry basis of 25 %.

干重怎么测？How is dry weight measured?

常用烘干法：在 103–105 °C 下烘到重量不再变化，此时的重量就是干重。Usually by oven-drying at 103–105 °C until the weight stops changing; that weight is the dry weight.

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

例如在「含水率计算器（干基/湿基互换、加水或烘干到目标）」中填 计算 = 由湿重和干重，湿重 = 120，干重 = 100，结果区显示：含水率（干基）：20 %；含水率（湿基）：16.667 %；水分重量：20For example, entering Calculate = From wet and dry weight, Wet weight = 120, Dry weight = 100 in the Moisture Content Calculator (Dry or Wet Basis, Water to Add or Remove) gives: Moisture (dry basis): 20 %; Moisture (wet basis): 16.667 %; Water weight: 20

哪些输入会被检查？Which inputs are validated?

「含水率计算器（干基/湿基互换、加水或烘干到目标）」会检查这些输入——「湿重」、「干重」：所选方式用到时必须填写，须大于 0；「含水率 %」、「目标含水率 %」：所选方式用到时必须填写；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 Moisture Content Calculator (Dry or Wet Basis, Water to Add or Remove) checks its inputs — "Wet weight", "Dry weight": required when the chosen option uses it, must be greater than 0; "Moisture %", "Target moisture %": required when the chosen option uses it; 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?

「含水率计算器（干基/湿基互换、加水或烘干到目标）」的设置：「计算」可选 由湿重和干重、干基 ↔ 湿基换算、调整到目标含水率（默认 由湿重和干重）；「湿重」默认 120；「干重」默认 100；「含水率 %」默认 20；「已知值的基准」可选 干基、湿基（默认 干基）；「目标含水率 %」默认 12。每次生成结果都按当前设置处理。Settings in the Moisture Content Calculator (Dry or Wet Basis, Water to Add or Remove) — "Calculate": From wet and dry weight, Convert dry ↔ wet basis, Adjust to a target (default From wet and dry weight); "Wet weight" default 120; "Dry weight" default 100; "Moisture %" default 20; "Basis of the known value": Dry basis, Wet basis (default Dry basis); "Target moisture %" default 12. 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?

「含水率计算器（干基/湿基互换、加水或烘干到目标）」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 Moisture Content Calculator (Dry or Wet Basis, Water to Add or Remove) 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.
