-There is a limit of 15 unique sources permitted in styles made with the style editor. You can check the number of sources used in **Settings** _Layer overview_ popover.
+使用样式编辑器制作的样式中最多只能包含15个唯一数据源。 您可以检查**设置** _图层概述_ 弹出框中使用的来源数量。
 
-Source compositing does not reduce the number of sources counted toward this limit. For example, if you are using a template style that references both the Mapbox Streets and Terrain tilesets (in other words, two tileset sources) and you add one custom tileset, even if the tilesets are bundled into one composite source, the total number of tileset sources used would be 3. In this example, you could add an additional 12 sources before hitting the 15 source limit.
+数据源合成不会减少计入此限制的数据源数量。 例如，如果你使用的模板样式同时引用了Mapbox街道和地形瓦片集（换句话说，是两个瓦片集数据源），并且你添加了一个自定义瓦片集，即使将这些瓦片集合成到一个复合数据源中，使用的瓦片集数据源的数量仍然为3。在此示例中，你可以在达到15个数据源限制之前添加其他12个数据源。

-#### Source compositing
+#### 数据源合成
 
-Any sources in your Mapbox Studio style are composited, or combined, by default. When source compositing is enabled, any Mapbox vector tilesets used and any custom vector tilesets added to your style in the future will be bundled into one composite source. Compositing improves label placement calculations across tilesets and makes maps load faster.
+默认情况下，你的Mapbox Studio样式的任何数据源源都是合成或组合的。 启用数据源合成后，将来使用的任何Mapbox矢量瓦片集和任何添加到你样式的自定义矢量瓦片集都将合成到一个复合数据源中。 合成改善了整个瓦片之间的标签放置计算，并使地图加载速度更快。
 
-Source composting can be turned on or off in the Settings section of the toolbar. When source compositing is turned off, you cannot make label placement calculations between layers from different sources.
+可以在工具栏的设置部分中打开或关闭数据源合成。 关闭数据源合成时，无法在来自不同数据源的图层之间进行标签放置计算。
 
-According to the [Mapbox Vector Tile Specification](https://docs.mapbox.com/vector-tiles/specification/), no two vector layers in a vector tileset may have the same ID. If you try to composite sources with the same ID, a modal will be displayed in the style editor to walk you through resolving the name conflicts.
+根据[Mapbox矢量瓦片规范](https://docs.mapbox.com/vector-tiles/specification/)，矢量瓦片集中的两个矢量图层都不能具有相同的ID。 如果你尝试使用相同的ID组合数据源，则会在样式编辑器中显示一个模式，来引导你解决名称冲突。
