 ### Aligned timeseries
 
-There is a situation that multiple measurements of an entity are sampled simultaneously in practical applications, forming multiple timeseries aligned on a time column.
+There is a situation that multiple measurements of an entity are sampled simultaneously in practical applications, forming multiple timeseries with the same time column. Such a group of timeseries can be modeled as aligned timeseries in Apache IoTDB.
 
-By using aligned timeseries, the timestamp columns of a group of aligned timeseries need to be stored only once in memory and disk when inserting data, instead of once per timeseries.

 It would be best if you created a group of aligned timeseries at the same time.

 ### 对齐时间序列（Aligned Timeseries）
 
-在实际应用中，存在某些实体的多个物理量**同时采样**，形成在时间列上对齐的多条时间序列。
+在实际应用中，存在某些实体的多个物理量**同时采样**，形成一组时间列相同的时间序列，这样的一组时间序列在Apache IoTDB中可以建模为对齐时间序列。
 
-通过使用对齐的时间序列，在插入数据时，一组对齐序列的时间戳列在内存和磁盘中仅需存储一次，而不是每个时间序列存储一次。

 对齐的一组时间序列最好同时创建。
