多线程计算多分批计算

By default, Excel recalculates all the formulas in your worksheet automatically when you open your worksheet or change any entries, formulas, or names on which your formulas depend. If you worksheet is large, with many formulas, this can take several seconds or minutes.

默认情况下，当您打开工作表或更改公式所依赖的任何条目，公式或名称时，Excel会自动重新计算工作表中的所有公式。 如果您的工作表很大，有许多公式，则可能需要几秒钟或几分钟。

While the formulas are being recalculated, the mouse pointer changes to an hourglass and you can’t make any changes to the worksheet.

重新计算公式时，鼠标指针将变为沙漏，并且您无法对工作表进行任何更改。

You may want to temporarily turn off automatic calculation to save time until you are finished entering and changing the formulas in your worksheet. This is done easily, and we will show you how.

您可能需要暂时关闭自动计算以节省时间，直到在工作表中输入和更改公式为止。 这很容易完成，我们将向您展示。

NOTE: If you don’t want to turn off the automatic calculation feature, and you have multiple processors in your computer, you can turn on the multi-threading feature, which could speed up the recalculation of your formulas by a little bit, depending on how many processors your computer has. We will show you how to turn on this option later in this article.

注意：如果您不想关闭自动计算功能，并且计算机中有多个处理器，则可以打开多线程功能，这可能会加快重新计算公式的速度，具体取决于您的计算机有多少个处理器。 我们将在本文后面的部分中向您展示如何打开此选项。

To disable the automatic calculation feature, open Excel and click the FILE tab.

若要禁用自动计算功能，请打开Excel并单击“文件”选项卡。

Click the Options item in the menu on the left.

单击左侧菜单中的选项项目。

On the Excel Options dialog box, click Formulas in the menu on the left.

在“ Excel选项”对话框上，单击左侧菜单中的“公式”。

Scroll down to the Calculation options section and select Manual to prevent the formulas from being calculated every time you make a change to a value, formula, or name or open a worksheet containing formulas.

向下滚动到“计算选项”部分，然后选择“手动”以防止每次更改值，公式或名称或打开包含公式的工作表时都无法计算公式。

The following list defines the options available in the Calculation options section:

下表定义了“计算选项”部分中可用的选项：

• Automatic – Calculates all dependent formulas and updates open or embedded charts every time you make a change to a value, formula, or name. This is the default setting for each new worksheet.
  自动–计算所有相关公式，并在每次更改值，公式或名称时更新打开或嵌入的图表。 这是每个新工作表的默认设置。
• Automatic Except for Data Tables – Calculates all dependent formulas and updates open or embedded charts, but it does not calculate data tables created with the Data Table feature. To recalculate data tables when this option button is selected, click the Calculate Now (F9) command button on the Formulas tab of the Ribbon or press F9 in the worksheet.
  数据表自动除外–计算所有相关公式并更新打开或嵌入的图表，但不计算使用“数据表”功能创建的数据表。 若要在选择此选项按钮时重新计算数据表，请在功能区的“公式”选项卡上单击“立即计算(F9)”命令按钮，或在工作表中按F9。
• Manual – Calculates open worksheets and updates open or embedded charts only when you click the Calculate Now (F9) command button on the Formulas tab of the Ribbon or press F9 or Ctrl+= in the worksheet.
  手动–仅在单击功能区的“公式”选项卡上的“立即计算(F9)”命令按钮或在工作表中按F9或Ctrl + =时，才计算打开的工作表并更新打开或嵌入的图表。
• Recalculate Workbook before Saving – Calculates open worksheets and updates open or embedded charts when you save them even when the Manually option button is selected. If you don’t want to updating dependent formulas and charts every time you save, turn this option off.
  保存之前重新计算工作簿–即使选择了“手动”选项按钮，也可以计算打开的工作表并在您保存打开或嵌入的图表时对其进行更新。 如果您不想每次保存时都更新相关的公式和图表，请关闭此选项。
• Enable Iterative Calculation – Sets the iterations, that is, the number of times that a worksheet is recalculated, when performing goal seeking or resolving circular references to the number displayed in the Maximum Iterations text box. For more information about goal seeking or resolving circular references, see Excel’s help file.
  启用迭代计算–设置迭代，即在执行目标搜索或解决对“最大迭代次数”文本框中显示的数字的循环引用时，重新计算工作表的次数。 有关寻求目标或解决循环引用的更多信息，请参见Excel的帮助文件。
• Maximum Iterations – Sets the maximum number of iterations (100 by default) when the Enable iterative calculation check box is selected.
  最大迭代次数–选中“启用迭代计算”复选框时，设置最大迭代次数(默认为100)。
• Maximum Change – Sets the maximum amount of change to the values during each iteration (0.001 by default) when the Enable iterative calculation check box is selected.
  最大变化–选中“启用迭代计算”复选框时，将每次更改的最大变化量设置为值(默认为0.001)。

You can also switch among the three main calculation options using the Calculation Options button in the Calculation section of the Formulas tab on the Ribbon. However, if you want to set the iteration options, you must use the Formulas page on the Word Options dialog box.

您还可以使用功能区上“公式”选项卡的“计算”部分中的“计算选项”按钮在三个主要计算选项之间进行切换。 但是，如果要设置迭代选项，则必须使用“ Word选项”对话框上的“公式”页面。

Excel 2013 has a multi-threading feature that allows you to reduce the time it takes to calculate complex formulas. If you would rather not turn off automatic calculation, you can try using this feature (if you have multiple processors in your computer) to reduce calculation time.

Excel 2013具有多线程功能，可让您减少计算复杂公式所需的时间。 如果您不想关闭自动计算，则可以尝试使用此功能(如果您的计算机中有多个处理器)以减少计算时间。

To enable the multi-threading feature, click the FILE tab and select Options to open the Excel Options dialog box, as mentioned earlier. Click Advanced in the menu on the left.

要启用多线程功能，请单击“文件”选项卡，然后选择“选项”以打开“ Excel选项”对话框，如前所述。 点击左侧菜单中的高级。

Scroll down to the Formulas section and select the Enable multi-threaded calculation check box so there is a check mark in the box. You can specify manually how many threads to use, or you can tell Excel to Use all processors on this computer.

向下滚动到“公式”部分，然后选中“启用多线程计算”复选框，以使该复选框中有一个复选标记。 您可以手动指定要使用的线程数，也可以告诉Excel使用此计算机上的所有处理器。

If you have other programs running on your computer, you may not want to use all the processors on your computers to recalculate the formulas in your Excel spreadsheets.

如果计算机上有其他程序正在运行，则可能不希望使用计算机上的所有处理器来重新计算Excel电子表格中的公式。

Test out different combinations of the Automatic Calculation and Multi-Threaded features to see what works best for you on your computer.

测试自动计算和多线程功能的不同组合，以查看最适合您的计算机的功能。
