previous row

When the teacher came in the forefront of the school, forget the previous row, good management education system can stimulate the continuing success in the future.

当老师走在学校的最前列，忘记前行时，好的管理教学制度能激发其百尺竿头，更进一步。

If you need only to compute the distance and not alignments, as is usually the case, it is easy to reduce this to O ( n), since only the previous row is required to compute the next.

如果您只需要计算距离，不需要校准，就像通常情况那样，那么可以很容易地把空间需求降到O（n），因为计算下一行只需要前面一行。

If the focus is already in the first cell of the row, moves the focus to the last cell in the previous row.

如果焦点已经位于此行中的第一个单元格，则将焦点移到前一行的最后一个单元格。

When a row in a temporal table is updated, DB2 updates the row and DB2 will automatically move the previous version of the row to a history table.

当时态表中的一行被更新时，DB2更新该行并自动将该行的以前版本转移到一个历史表中。

This only increases the number of computations by a factor of two but requires increased overhead for bookkeeping ( since the samples from the previous row must be stored).

这种方法只需要增加计算的次数但是需要对原先的行进行保存。

Once a row has been read, the previous row is no longer available.

只要一行被读取, 之前的数据就不再有效.
