双语例句

• If more than one column is aggregated using the same grouping key or without a grouping key, then all the aggregations are computed within the same operation with a single pass over the data.
  如果利用相同的分组关键字或者没有分组关键字，来聚合多个列，那么，所有的聚合都在单个数据传递中的相同操作中进行。
• But if you use multiple aggregations with the same grouping keys, or multiple counting functions that count the same column, it will not significantly increase the execution time of the rule.
  但是，如果使用具有相同分组关键字的多个聚合，或者对相同列进行计数的计数函数，其不会显著增加规则的执行时间。
• A measure must have one aggregation with an empty list of dimensions, and any other aggregations must each have an explicit list of dimensions.
  一个度量必须有一个维列表为空的聚合，其他聚合必须都具有明确的维列表。
• In aggregated levels, members are based on aggregations of subordinate levels.
  在聚合级别中，各成员基于其从属级别的聚合。
• Composite applications are aggregations of user interface ( UI) components that are loosely coupled to support intercomponent communication.
  复合应用程序由松散耦合的用户界面（UI）组件组成，支持组件之间的通信。
• The atoms of the different chemical elements are different aggregations of atoms of the same kind.

• If a rule must contain one aggregation, then you can compute additional aggregations on different columns in the same rule without impacting performance, as long as the grouping keys are the same.
  如果规则必须包含一个聚合，那么可以在同一规则中，对不同列计算附加聚合，只要分组关键字相同，就不会影响性能。
• You can compute aggregations on the whole column, or on subgroups that are specified by the grouping column given as the second parameter of the function.
  可在整个列上计算聚合，或者由作为函数的第二个参数所给出的分组列指定的子组上计算聚合。
