双语例句
- Size of current aggregations in memory. This count is an estimate.
内存中的当前聚合的大小。此计数为估计值。 - 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。 - Numerical aggregations can be computed in a rule by using one of the following functions
可利用以下函数之一，来在一个规则中计算大量聚合 - Start by generating the query using the first aggregation function ( SUM in the example) in the measure's list of aggregations to aggregate the template expression.
先使用度量的聚合列表中的第一个聚合函数（在这个示例中是SUM）对表达式模板进行聚合，产生一个查询。 - 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。 - 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。 - 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。 - The atoms of the different chemical elements are different aggregations of atoms of the same kind.
不同化学元素的原子是同类原子的不同聚合物。 - UML has three ways of representing relationships: aggregation, composition, and association.
UML有三种方法来表示关系：聚合（aggregations）、复合（compositions）和关联（associations）。 - In this wizard, you can optimize aggregations for future query performance based on the query history of your cube.
在本向导中，您可以根据多维数据集的查询历史来优化聚合，以提高将来的查询性能。
