If you have an animation in your PowerPoint presentation that’s moving just a little too slow (or too fast), you can adjust the speed of the animation to match your desired timing. Here’s how it’s done.

如果PowerPoint演示文稿中的动画的移动速度太慢(或太快)，则可以调整动画的速度以使其符合所需的时间。 这是完成的过程。

First, select the object in your slide that contains the animation. If you haven’t already assigned one to your object, you can do so by selecting one of the many options in the “Animation” group of the “Animations” tab. We’ll assign our image the “Grow & Turn” animation.

首先，在幻灯片中选择包含动画的对象。 如果尚未将一个分配给对象，则可以通过选择“动画”选项卡的“动画”组中的多个选项之一来进行分配。 我们将为我们的图像分配“ Grow＆Turn”动画。

By default, the duration of the animation is set to one second. You can check out a preview of the animation by selecting “Preview” in the far left of the “Animations” tab.

默认情况下，动画的持续时间设置为一秒。 您可以通过选择“动画”选项卡最左侧的“预览”来签出动画的预览。

Now that you’ve seen the animation, it’s time to adjust the speed. Still in the “Animations” tab, head over to the “Timing” group. Here, you’ll see the “Duration” option. As we mentioned, you’ll notice that it’s currently set for one second. Adjust the duration (by 0.25 second increments) by selecting the up and down arrows in the duration box. Alternatively, just type the amount of time in the box.

既然您已经看过动画，现在该调整速度了。 仍在“动画”选项卡中，转到“计时”组。 在这里，您会看到“持续时间”选项。 如前所述，您会注意到它当前设置为一秒钟。 通过选择持续时间框中的向上和向下箭头来调整持续时间(以0.25秒为增量)。 或者，只需在框中输入时间。

Now, when you play the animation, it will play out at the set duration.

现在，当您播放动画时，它将按设置的持续时间播放。

As a nice little aside, if you have multiple animations and have set them to start subsequently by selecting the “After Previous” start option, you can adjust the timing at which the next animation is executed. To do so, adjust the “Delay” option (00.00 by default) to the desired amount of time. This option is also adjusted at 0.25 second increments.

顺便说一句，如果您有多个动画并通过选择“ After Previous”开始选项将它们设置为随后开始，则可以调整执行下一个动画的时间。 为此，将“延迟”选项(默认为00.00)调整为所需的时间。 此选项也以0.25秒为增量进行调整。

Once the first animation plays out, the following animation will begin in the set amount of time.

一旦播放了第一个动画，随后的动画将在设置的时间内开始播放。
