A collection of data is called a data set, and a singleobservation a data point.
全部资料的总和叫数据集合，单个观察数据叫数据点。

If you're dealing with only a singleobservation point, which is usually the case, you can use either the capture or bubbling phase — there's no real difference.
如果处理单个观测点——这也是最常见的情况，使用哪个阶段都行，两者没有实际区别。
